PURPOSE

Women with locally unresectable and inflammatory breast carcinoma (IBC) have an approximately 30% 5-year disease-free survival (DFS) rate with conventional multimodality therapy. A short but dose-intensive multimodality phase II trial was designed in an attempt to improve outcome in stage IIIB disease. Mastectomy was performed after high-dose therapy to evaluate pathologic response to treatment.

METHODS

Women with newly diagnosed disease received four 2-week cycles of doxorubicin 90 mg/m2 with granulocyte colony-stimulating factor (G-CSF), followed by cyclophosphamide 6,000 mg/m2, thiotepa 500 mg/m2, and carboplatin 800 mg/m2 (CTCb) with marrow and peripheral-blood progenitor cell (PBPC) support. Local therapy consisted of mastectomy and radiotherapy. Tamoxifen (5 years) was begun if the patient was estrogen receptor-positive (ER+).

RESULTS

Fifty women (46 stage IIIB [91% IBC], four stage IIIA) entered the study and 47 are assessable. Ten had mastectomy before any systemic therapy (seven with pathologic IBC, three with residual tumor after mastectomy). Eighty percent received full-dose doxorubicin with 60% on schedule. Clinical response rates to induction were 15% complete response (CR), 5% very good partial response (VGPR), 59% partial response (PR), and 21% minor response (MR)/stable disease (SD). Mastectomy after CTCb in 37 patients showed a 14% pathologic CR rate, 29% microscopic foci in breast and/or axilla, and 57% gross tumor. Fifteen (32%) patients have relapsed (median, 17 months post-CTCb). The 30-month DFS is estimated at 64%. For those in pathologic CR, with microscopic, or with gross disease remaining after CTCb, the 30-month DFS is estimated at 100%, 70%, and 38%, respectively. Those with zero, one to three, or > or = four positive nodes at axillary dissection had a median DFS of 31, 18, and 13 months, respectively.

CONCLUSION

This short but dose-intensive multimodality approach for stage IIIB breast carcinoma is feasible with encouraging results to date.

PURPOSE

To determine the incidence of myelodysplasia (MDS) and/or acute leukemia (AL) in breast cancer patients after high-dose chemotherapy (HDC) with a single conditioning regimen and autologous bone marrow transplant (ABMT), and analyze the cytogenetic abnormalities that arise after HDC.

PATIENTS AND METHODS

We retrospectively reviewed the records of 864 breast cancer patients who underwent ABMT at Duke University Medical Center, Durham, NC, from 1985 through 1996 who received the same preparative regimen of cyclophosphamide 1,875 mg/m2 for 3 days, cisplatin 55 mg/m2 for 3 days, and BCNU 600 mg/m2 for 1 day (CPB). Pretransplant cytogenetics were analyzed in all patients and posttransplant cytogenetics were evaluated in four of five patients who developed MDS/AL.

RESULTS

Five of 864 patients developed MDS/AL after HDC with CPB and ABMT. The crude cumulative incidence of MDS/AL was 0.58%. The Kaplan-Meier curve shows a 4-year probability of developing MDS/AL of 1.6%. Pretransplant cytogenetics performed on these five patients were all normal. Posttransplant cytogenetics were performed on four of five patients and they were abnormal in all four, although only one patient had the most common cytogenetic abnormality associated with secondary MDS/AL (chromosome 5 and/or 7 abnormality).

CONCLUSION

Whereas MDS/AL is a potential complication of HDC with CPB and ABMT, the incidence in this series of patients with breast cancer was relatively low compared with that reported in patients with non-Hodgkin's lymphoma who underwent ABMT. The cytogenetic abnormalities reported in this group of breast cancer patients were not typical of those seen in prior reports of secondary MDS/AL and appear to have occurred after HDC.

Published: February 2017

PURPOSE

We performed a clinical trial to determine whether postoperative adjuvant chemotherapy with two drugs versus one drug could prolong survival.

PATIENTS AND METHODS

From 1985 to 1996, 85 patients with completely resected locally advanced gastric cancer were enrolled. The subjects were randomized into two treatment groups, as follows: mitomycin (MMC) 10 to 20 mg/m2 intravenously (i.v.) on day 1 every 6 weeks plus ftorafur (FT) 500 mg/m2/d for 36 consecutive days; or MMC alone, 10 to 20 mg/m2 i.v. every 6 weeks. All courses were repeated four times.

RESULTS

After a median follow-up duration of 62 months, the overall 5-year survival rates were 67% for the MMC-FT group versus 44% for the MMC group (P = .04). Subgroup analysis to compare survival curves using the method of Mantel-Cox showed survival rates significantly in favor of the MMC-FT group in the subsets of patients with node-negative disease (P = .01) and those whose disease was stage IB or II (P = .008).

CONCLUSION

Significantly better survival results were observed for MMC-FT versus MMC alone. Subset analysis suggest a strong benefit in patients with node-negative and early-stage resected gastric cancer.
Reduced integrin alpha3 expression as a factor of poor prognosis of patients with adenocarcinoma of the lung.
Authors: Adachi M , Taki T , Huang C , Higashiyama M , Doi O , Tsuji T , Miyake M
Published: February 2017

PURPOSE

We investigated the possible association between integrin alpha3 and motility-related protein (MRP-1), cluster of differentiation antigen 9 (CD9) gene expression in non-small-cell lung cancer (NSCLC) and evaluated the prognostic significance of integrin alpha3 expression.

PATIENTS AND METHODS

We performed a retrospective study of integrin alpha3 and MRP-1/CD9 expression in resected tumor tissues from 151 NSCLC patients using quantitative reverse-transcriptase polymerase chain reaction (RT-PCR) and immunohistochemistry.

RESULTS

The ratio of integrin alpha3/beta-actin expression ranged from 0 to 5.87 (mean was 0.80; median, 0.70). Using the cutoff value of 0.7, there were 78 (52%) integrin alpha3-positive tumors and 73 (48%) tumors with reduced integrin alpha3 expression. The immunohistochemical results agreed well with those of the RT-PCR assays, and 88% had no discrepancy. In case of discrepancy, the results of RT-PCR were used in specimen classification. Integrin alpha3 gene expression was independent from MRP-1/CD9 gene expression. No significant association was found between integrin alpha3 expression and the patients' clinical characteristics. The overall survival rate of patients with integrin alpha3-positive NSCLCs was only slightly better than that of individuals whose tumors had reduced integrin alpha3 expression (55.9% v 47.1%; P = .085). By comparison, the overall survival rate of patients with integrin alpha3-positive adenocarcinomas was strikingly greater than in those whose tumors had reduced gene expression (54.4% v 35.2%; P = .004). Multivariate analysis with the Cox regression model of NSCLC and adenocarcinoma indicated that integrin alpha3 expression correlated better (P = .0188 and P = .0008, respectively) with the overall survival rate than other variables, except lymph node status.

CONCLUSION

No significant association was found between integrin alpha3 and MRP-1/CD9 gene expression in lung cancer. However, reduced integrin alpha3 expression is a poor prognosis factor in patients with adenocarcinomas.
Prospective investigation of positron emission tomography in lung nodules.

Published: February 2017

PURPOSE

Solitary pulmonary nodules (SPNs) are commonly identified by chest radiographs and computed tomography (CT). Biopsies are often performed to evaluate the nodules further. An accurate, noninvasive diagnostic test could avoid the morbidity and costs of invasive tissue sampling. We evaluated the ability of fluorine-18 deoxyglucose positron emission tomography (FDG-PET) to discriminate between benign and malignant pulmonary nodules in a prospective, multicenter trial.

METHODS

Eighty-nine patients who had newly identified indeterminate SPNs on chest radiographs and CT were evaluated with FDG-PET. PET data were analyzed semiquantitatively by calculating standardized uptake values (SUVs) as an index of FDG accumulation and also by a visual scoring method. PET results were compared with pathology results.

RESULTS

Sixty SPNs were malignant and 29 were benign. Using SUV data, PET had an overall sensitivity and specificity for detection of malignant nodules of 92% and 90%. Visual analysis provided a slightly higher, but not statistically significant, sensitivity of 98% and lower specificity of 69%. For SPNs < or = 1.5 cm (34 of 89), the sensitivity and specificity of SUV and visual analysis were 80% and 95% and 100% and 74%, respectively.

CONCLUSION

FDG-PET can accurately characterize indeterminate SPNs. PET imaging provides a noninvasive method to evaluate indeterminate SPNs, which can reduce the need for invasive tissue biopsy.
Phase II study of vinorelbine in advanced and recurrent squamous cell carcinoma of the cervix.
Authors: Morris M , Brader K R , Levenback C , Burke T W , Atkinson E N , Scott W R , Gershenson D M
Published: February 2017

PURPOSE

To evaluate the efficacy and toxicity of intravenous vinorelbine as single-agent chemotherapy in patients with advanced or recurrent squamous cell carcinoma of the cervix.

PATIENTS AND METHODS

Between August 1993 and July 1995, 35 patients with advanced or recurrent squamous cell carcinoma of the cervix were entered onto this study. Patients had received no prior therapeutic chemotherapy. The initial dose of vinorelbine 30 mg/m2 was administered as a weekly intravenous infusion. Subsequent doses were unchanged, reduced, escalated, or omitted according to observed toxicity. Patients were evaluated for response and toxicity using standard Gynecologic Oncology Group (GOG) and World Health Organization criteria, respectively.

RESULTS

Thirty-three of 35 patients were assessable for response and 35 of 35 for toxicity. The overall response rate was 18% (one complete response [CR], five partial responses [PR]). The mean response duration was 5.2 months and the median survival from treatment for all patients was 11.0 months. The major toxicity was leukopenia, with 61% of patients who had grade 3 or 4. Gastrointestinal and neurotoxicity were infrequent and mild.

CONCLUSION

Vinorelbine has moderate activity in advanced or recurrent squamous cell carcinoma of the cervix. Further studies of combination regimens with this agent are justified in this patient population.

Published: February 2017

PURPOSE

To investigate the antitumor activity and safety of paclitaxel in patients with advanced human immunodeficiency virus (HIV)-associated Kaposi's sarcoma (KS).

PATIENTS AND METHODS

Twenty-nine patients with advanced HIV-associated KS were enrolled. The patients were overall quite immunosuppressed (median CD4 count, 15 cells/microL). Paclitaxel was initially administered at 135 mg/m2 over 3 hours every 3 weeks without filgrastim support; the dose was increased as tolerated to a maximum of 175 mg/m2. Patients who failed to respond or progressed could then receive filgrastim support or paclitaxel administered over 96 hours.

RESULTS

Of 28 assessable patients, 20 had major responses (18 partial responses [PRs], one clinical complete response [CR], and one CR), for a major response rate of 71.4% (95% confidence interval [CI], 51.3% to 86.8%). Each of the five patients with pulmonary KS responded, as did all four assessable patients who had previously received anthracycline therapy for KS. Of six patients who went on to receive a 96-hour infusion of paclitaxel, five had major responses. Neutropenia was the most frequent dose-limiting toxicity; possible novel toxicities included late fevers, late rash, and eosinophilia. Two patients developed an elevated creatinine concentration and one cardiomyopathy.

CONCLUSION

Paclitaxel has substantial activity against advanced HIV-associated KS as a single agent, even in patients with pulmonary involvement or who had previously received anthracyclines. Further research is needed to define the optimal treatment schedule and its role vis-a-vis the other available therapies for this disease.

Published: February 2017

PURPOSE

To evaluate the roles of granisetron and dexamethasone for emesis control on days 2 through 7 after the administration of cisplatin in doses of 50 mg/m2 or greater to patients who had not previously received chemotherapy.

PATIENTS AND METHODS

Four hundred thirty-five eligible and assessable patients were randomized to one of two arms in a double-blind fashion: arm A; granisetron 3 mg intravenous (i.v.) plus dexamethasone 10 mg i.v. prechemotherapy followed by granisetron 1 mg orally at 6 and 12 hours, then granisetron 1 mg orally and dexamethasone 8 mg orally twice daily on days 2 through 7 (219 patients); arm B; as in arm A but with placebo substituted for granisetron on days 2 through 7 (216 patients). All patients completed diaries in which episodes of emesis and severity of nausea were recorded.

RESULTS

The addition of granisetron on days 2 through 7 had no discernable impact on nausea and vomiting during this period.

CONCLUSION

The administration of a 5-hydroxytryptamine3, receptor (5-HT3) antagonist, in this case granisetron, after 24 hours conferred no benefit. This negative result needs to be assessed in light of conflicting literature, but at present it does not appear that the routine use of these drugs in this setting is justified.
Progress of clinical oncology guidelines development using the Practice Guidelines Development Cycle: the role of practitioner feedback.
Authors: Browman G P , Newman T E , Mohide E A , Graham I D , Levine M N , Pritchard K I , Evans W K , Maroun J A , Hodson D I , Carey M S , Cowan D H
Published: February 2017

PURPOSE

To present an update on the development of oncology practice guidelines (PGs) using the Practice Guidelines Development Cycle (Cycle), and to present the results of surveys of oncologists on the first 10 guidelines from the Cancer Care Ontario Practice Guidelines Initiative.

METHODS

Practitioners' opinions about guidelines in development were sought using a mail survey method with systematic follow-up. Practitioners were identified by cancer center representatives. Survey packages included evidence-based recommendations (EBRs) and a one-page, nine-item feedback questionnaire. Data were collected between February 1995 and February 1996.

RESULTS

Nine hundred fourteen surveys that pertained to 10 guidelines were mailed to 423 practitioners in Ontario. Practitioners included 112 medical oncologists/hematologists, 34 radiation oncologists, 195 surgeons, and 82 practitioners from other medical specialities. One hundred practitioners were located in cancer centers and 323 had community-based practices. The overall response rate by practitioner was 72% and by survey questionnaire, 70%. For the five questionnaire items that assessed guideline quality, approval ratings ranged from 86% to 92%. For the 10 recommendations, 77% ( 63% to 82%) of respondents agreed that the EBR could be approved as a PG. Response and approval rates were consistent across medical specialities and locations of practice.

CONCLUSION

The process of obtaining practitioner feedback in the development of PGs is both feasible and useful. The high response rates to the survey indicate that it is possible to obtain broad participation in evidence-based guidelines development throughout Ontario. The changes made to the EBRs in response to feedback suggest that practitioners' opinions can be valuable in shaping evidence-based guidelines.

Published: February 2017

DESIGN

To perform a meta-analysis of all randomized trials that compared chemotherapy (CT) alone versus combined modality treatment (CT + radiotherapy [RT]) for which individual patient data could be made available.

PATIENTS AND METHODS

Data on 1,740 patients treated on 14 different trials that included 16 relevant comparisons have been analysed. Eight comparisons were designed to evaluate the benefit of additional RT after the same CT (CT1 v CT1 + RT; additional RT design). Eight comparisons were designed to evaluate whether RT in a combined modality setting can be substituted by CT using either more cycles of the same CT or regimens that contain additional drugs (CT1 + CT2 v CT1 + RT or CT1 v CT2 + RT; parallel RT/CT design).

RESULTS

Additional RT showed an 11% overall improvement in tumor control rate after 10 years (P = .0001; 95% confidence interval [CI], 4% to 18%). No difference could be detected with respect to overall survival (P = .57; 95% CI, -10% to 4%). In contrast, when combined modality treatment was compared with CT alone in the parallel-design trials, no difference could be detected in tumor control rates (P = .43; 95% CI, -6% to 9%), but overall survival was significantly better after 10 years in the group that did not receive RT (P = .045; 8% difference; 95% CI, 1% to 15%). There were significantly fewer fatal events among patients in continuous complete remission (relative risk [RR], 1.73; 95% CI, 1.17 to 2.53; P = .005) if no RT was given.

CONCLUSION

Combined modality treatment in patients with advanced-stage Hodgkin's disease overall has a significantly inferior long-term survival outcome than CT alone if CT is given over an appropriate number of cycles. The role of RT in this setting is limited to specific indications.
Long-term survival in primary CNS lymphoma.
Authors: Abrey L E , DeAngelis L M , Yahalom J
Published: February 2017

PURPOSE

We have previously reported on 31 patients with primary CNS lymphoma (PCNSL) treated between 1986 and 1992 with methotrexate (MTX), cranial radiotherapy (RT), and high-dose cytarabine who remained free of disease longer than historical controls.

PATIENTS AND METHODS

We performed a follow-up analysis of our original cohort and now report their long-term survival and late treatment-related toxicity.

RESULTS

The median cause-specific survival was 42 months, with a five-year survival of 22.3% compared with 3% to 4% in historical controls treated with RT alone. Age less than 50 years at diagnosis was a significant prognostic factor for survival (P = .01). Median disease-free survival was 40.3 months; 15 patients relapsed, all but one in the CNS. Late treatment-related toxicity was observed in nearly one third of patients and those more than 60 years of age were at substantially higher risk (P < .0001).

CONCLUSION

Combined modality therapy for PCNSL has improved survival, but relapse is common and late neurologic toxicity is a significant complication. Although this approach is highly effective for younger patients, efficacious but less neurotoxic regimens need to be developed for older patients.

Published: February 2017

PURPOSE

The impact of treatment options on survival and late neurologic toxicity was investigated in a series of patients with primary cerebral lymphoma (PCL) and no known cause of immunosuppression.

PATIENTS AND METHODS

Prognostic factors for survival and treatment-induced late neurotoxicity were investigated in a retrospective series of 226 patients with PCL.

RESULTS

With a median follow-up of 76 months, the median overall survival was 16 months and 5-year survival was 19%. In a univariate analysis, age greater than 60 years, performance status, CSF protein level greater than 0.6 g/L, involvement of corpus callosum or subcortical grey structures, detectable lymphoma cells in CSF, increased serum lactate dehydrogenase (LDH), but not histological subtype, were significantly correlated with a poor survival. Treatment with chemotherapy versus radiotherapy alone (P = .05), high-dose methotrexate (HDMTX; P = .0007), and cytarabine (P = .04) correlated with a better survival in univariate analysis. Using the Cox model, age, performance status, and CSF protein were independently correlated with survival. After adjustment of these factors, treatment with an HDMTX-containing regimen remained the only treatment-related factor independently correlated with survival (P = .01). The projected incidence of treatment-induced late neurotoxicity was 26% at 6 years in this series, with a median survival from the diagnosis of late neurotoxicity of 12 months. Treatment with radiotherapy followed by chemotherapy was the only parameter correlated with late neurotoxicity in multivariate analysis (relative risk, 11.5; P = .0007).

CONCLUSION

Patients with PCL treated with regimens that included HDMTX followed by radiotherapy have an improved survival, but not a higher risk of late neurotoxicity as compared with other treatment modalities in this series.
Early treatment decisions with interferon-alfa therapy in early chronic-phase chronic myelogenous leukemia.
Authors: Sacchi S , Kantarjian H M , Smith T L , O'Brien S , Pierce S , Kornblau S , Beran M , Keating M J , Talpaz M
Published: February 2017

PURPOSE

To determine, in patients with Philadelphia chromosome (Ph)-positive chronic myelogenous leukemia (CML) on interferon alfa (IFNalpha), whether combining pretreatment characteristics and early response profiles would distinguish patients with differential benefits that would allow better decisions on subsequent therapy.

PATIENTS AND METHODS

A total of 274 patients treated from 1982 through 1990 with IFNalpha regimens were analyzed. A second group of 137 patients treated with IFNalpha and low-dose cytarabine (ara-C) between 1990 and 1994 was later used to confirm the guidelines derived from the original study group analysis. Patients' pretreatment factors and response to IFNalpha therapy at 3, 6, and 12 months were analyzed in relation to subsequent achievement of major cytogenetic response. After univariate analysis of prognostic factors, a multivariate analysis selected, at 6 months, independent pretreatment factors that added to the response status in predicting subsequent outcome. The results were then applied at the 3- and 12-month periods and confirmed in the subsequent population.

RESULTS

Response to IFNalpha therapy at 3, 6, and 12 months was a significant predictor of later major cytogenetic response. The presence of splenomegaly > or = 5 cm below the costal margin (BCM) or thrombocytosis > or = 700 x 10(9)/L pretreatment added significant independent prediction to response. At 6 months, patients with a partial hematologic response (PHR) or resistant disease had a less than 10% chance of achieving a later major cytogenetic response, as were those in complete hematologic response (CHR) and who had pretreatment splenomegaly and thrombocytosis. Applying the model at 3 months showed that only patients with < or = PHR and pretreatment splenomegaly or thrombocytosis at 3 months had such a low major cytogenetic response rate. Finally, at 12 months, patients with CHR still had a 15% to 25% chance of having a major cytogenetic response later if they did not have pretreatment splenomegaly and thrombocytosis.

CONCLUSION

This analysis allows better selection of patients with Ph-positive CML on IFNalpha therapy for continuation of IFNalpha versus changing therapy early in the course of CML. For treatment programs that choose to change patients to other investigational therapies (eg, intensive chemotherapy and/or autologous stem-cell transplantation [SCT]), baseline outcome expectations are provided for patients continued on IFNalpha therapy, against which the results of new approaches can be compared.
Allogeneic peripheral-blood progenitor-cell transplantation for poor-risk patients with metastatic breast cancer.

Published: February 2017

PURPOSE

To evaluate the feasibility of allogeneic peripheral-blood progenitor-cell (PBPC) transplantation and to assess graft-versus-tumor effects in patients with metastatic breast cancer.

PATIENTS AND METHODS

Ten patients with metastatic breast cancer that involved the liver or bone marrow were treated with high-dose chemotherapy and allogeneic PBPC transplantation. The median age was 42 years (range, 29 to 55). The median number of metastatic sites was three (range, one to five). The conditioning regimen was cyclophosphamide (6,000 mg/m2), carmustine (BCNU; 450 mg/m2), and thiotepa (720 mg/m2) (CBT regimen). Patients received graft-versus-host disease (GVHD) prophylaxis using cyclosporine- or tacrolimus-based regimens.

RESULTS

All patients had engraftment and hematologic recovery. Three patients developed grade > or = 2 acute GVHD and four patients had chronic GVHD. After transplantation, one patient was in complete remission (CR), five achieved a partial remission (PR), and four had stable disease (SD). In two patients, metastatic liver lesions regressed in association with skin GVHD after withdrawal of immunosuppressive therapies. The median follow-up time was 408 days (range, 53 to 605). The median progression-free survival duration was 238 days (range, 53 to 510).

CONCLUSION

We conclude that allogeneic PBPC transplantation is a feasible procedure for patients with poor-risk metastatic breast cancer. The regression of tumor associated with GVHD provides suggestive clinical evidence that graft-versus-tumor effects may occur against breast cancer. Compared with autologous transplantation, allogeneic PBPC transplantation is associated with the additional risks of GVHD and related infections. Allogeneic transplantation should only be performed in the context of clinical trials and its ultimate role requires demonstration of improved progression-free survival.
EWS-FLI1 fusion transcript structure is an independent determinant of prognosis in Ewing's sarcoma.

Published: February 2017

PURPOSE

More than 90% of Ewing's sarcomas (ES) contain a fusion of the EWS and FLI1 genes, due to the t(11;22)(q24;q12) translocation. At the molecular level, the EWS-FLI1 rearrangements show great diversity. Specifically, many different combinations of exons from EWS and FLI1 encode in-frame fusion transcripts and result in differences in the length and composition of the chimeric protein, which functions as an oncogenic aberrant transcription factor. In the most common fusion type (type 1), EWS exon 7 is linked in frame with exon 6 of FLI1. As the fundamental pathogenetic lesion in ES, the molecular heterogeneity of these fusion transcripts may have functional and clinical significance.

PATIENTS AND METHODS

We performed a clinical and pathologic analysis of 112 patients with ES in which EWS-FLI1 fusion transcripts were identified by reverse-transcriptase polymerase chain reaction (RT-PCR). Adequate treatment and follow-up data were available in 99 patients treated with curative intent. Median follow-up in these 99 patients was 26 months (range, 1 to 140 months). Univariate and multivariate survival analyses were performed that included other prognostic factors, such as age, tumor location, size, and stage.

RESULTS

Among the 99 patients suitable for survival analysis, the tumors in 64 patients contained the type 1 fusion and in 35 patients contained less common fusion types. Stage at presentation was localized in 74 patients and metastatic in 25. Metastases (relative risk [RR] = 2.6; P = .008), and type 1 EWS-FLI1 fusion (RR = 0.37; P = .014) were, respectively, independent negative and positive prognostic factors for overall survival by multivariate analysis. Among 74 patients with localized tumors, the type 1 EWS-FLI1 fusion was also a significant positive predictor of overall survival (RR = 0.32; P = .034) by multivariate analysis.

CONCLUSION

EWS-FLI1 fusion type appears to be prognostically relevant in ES, independent of tumor site, stage, and size. Further studies are needed to clarify the biologic basis of this phenomenon.
Neoadjuvant chemotherapy and bladder-sparing surgery for invasive bladder cancer: ten-year outcome.
Authors: Herr H W , Bajorin D F , Scher H I
Published: February 2017

PURPOSE

To evaluate the 10-year outcome of patients with invasive (T2-3N0M0, staged according to the tumor, node, metastasis system) bladder cancer who responded completely to a combination of methotrexate, vinblastine, adriamycin, and cisplatin (MVAC) chemotherapy followed by bladder-sparing surgery.

PATIENTS AND METHODS

Of 111 surgical candidates who received neoadjuvant MVAC, 60 (54%) achieved a complete clinical response (T0) on transurethral resection (TUR) of the primary tumor site. Of these, 28 requested follow-up with TUR alone, 15 had a partial cystectomy, and 17 elected a radical cystectomy. The patients were followed up for a median of 10 years (range, 8 to 13 years).

RESULTS

Of 43 patients who had bladder-sparing surgery, 32 (74%) are alive, which includes 25 (58%) with an intact functioning bladder. Twenty-four patients (56%) developed bladder tumor recurrences from 5 to 96 months, which were invasive in 13 (30%) and superficial in 11 (26%). Thirteen patients required a salvage cystectomy, of whom 6 died, which includes 4 (9%) from a new invasive neoplasm. Of the 17 patients who had radical cystectomy, 11 (65%) are alive.

CONCLUSION

The majority of patients with invasive bladder tumors who achieve T0 status after neoadjuvant MVAC chemotherapy preserve their bladders for up to 10 years with bladder-sparing surgery. The bladder remains at risk for new invasive tumors. Cystectomy salvages the majority, but not all, of relapsing patients.

PURPOSE

A prospective randomized multicenter trial was performed to evaluate the contribution of simultaneously administered chemotherapy (CT) and radiotherapy (RT) in previously untreated patients with unresectable stage III/IV head and neck cancer.

PATIENTS AND METHODS

Patients with locoregionally advanced head and neck cancer were treated either with RT alone (arm A) or simultaneous RT plus CT (RCT; arm B). RT was identical in both arms and administered in three courses with 13 fractions of 1.8 Gy each twice daily. During one course, from day 3 to 11, 23.4 Gy was delivered. In arm B, cisplatin (CDDP) 60 mg/m2, fluorouracil (5-FU) 350 mg/m2 by intravenous (i.v.) bolus, and leucovorin (LV) 50 mg/m2 by i.v. bolus were given on day 2, and 5-FU 350 mg/m2/24 hour by continuous infusion and LV 100 mg/m2/24 hours by continuous infusion were given from day 2 to 5. Treatment was repeated on days 22 and 44; a total RT dose of 70.2 Gy was administered. Treatment breaks were scheduled from days 12 to 21 and days 34 to 43.

RESULTS

From 1989 to 1993, 298 patients were enrolled and 270 patients were assessable. Acute mucositis grade 3 or 4 was more frequent in arm B (38%) than in arm A (16%) (P < .001). Total treatment time was significantly longer in arm B than in arm A (P < .001) due to prolonged breaks. According to hematologic toxicity, scheduled drug doses were given in 74% of patients for the second course and 46% for the third course. The 3-year overall survival rate was 24% in arm A and 48% in arm B (P < .0003). The 3-year locoregional control rate was 17% in arm A and 36% in arm B (P < .004). Both arms showed similar distant failure patterns (arm A, 13 of 140; arm B, 12 of 130). Serious late side effects were not significantly different between treatment arms (arm A, 6.4%; arm B, 10%; not significant).

CONCLUSION

Concomitant CT offered improved disease control and survival in advanced head and neck cancer patients. Due to increased acute toxicity, more supportive care is demanded when CT is given simultaneously. Increased total treatment time does not exert a negative impact on outcome in this combined modality regimen.

PURPOSE

The prognostic role of the site of the primary breast cancer has not been clarified. This study aimed to gather more information about this issue from a large series of patients with long-term follow-up data.

PATIENTS AND METHODS

Data from 2,396 patients treated for early breast cancer with a conservative approach were reviewed (1973 to 1989). In 1,619 patients, the tumor had a lateral site, while in 777 cases, it was situated in the internal/central quadrants. The characteristics of the two groups were well balanced, apart from axillary nodal metastases, which were more frequent for lateral tumors (38.1% v 26.3%).

RESULTS

Analysis of distant metastases indicated that the regression coefficient associated with tumor site was significant and the hazards ratio estimate was 1.291, which indicates the risk of distant metastases was increased by approximately 30% for internal/central tumors. The analysis of overall survival yielded a significant coefficient and a hazards ratio of 1.192, which indicates an approximately 20% increase of mortality for internal/central tumors.

CONCLUSION

Early breast cancers situated in central/ internal quadrants have a worse prognosis compared with those in lateral quadrants, in terms of distant metastases and survival. Irradiation of the internal mammary chain for internal/medial tumors could be suggested, but, to date, the therapeutic strategy is still controversial.
Quality of life and preferences for treatment following systemic adjuvant therapy for early-stage breast cancer.

Published: February 2017

PURPOSE

To evaluate the quality of life (QOL) of breast cancer patients who survived 2 to 5 years following initiation of adjuvant cytotoxic and/or hormonal therapy and to characterize relationships between QOL and patient physical symptoms, sexual function, and preferences regarding adjuvant treatment.

PATIENTS AND METHODS

Eighty-six patients who had completed systemic adjuvant therapy for early-stage breast cancer between 1988 and 1991 were surveyed by written questionnaire and telephone interview. Sociodemographic information was obtained for each patient, and patients were asked to complete the Functional Living Index-Cancer (FLIC), the Symptom Distress Scale (SDS), the Medical Outcomes Study (MOS) Short Form 36 (SF-36), a series of questions regarding sexual function, and a survey about preferences for adjuvant therapy in relation to possible benefit.

RESULTS

The mean FLIC score among all patients was 138.3 (+/- 12.2), which suggests a high level of QOL. The reported frequency of moderate to severe symptoms was generally low (ie, < 15%), with fatigue (31.4%), insomnia (23.3%), and local numbness at the site of surgery (22.1%) occurring with greatest frequency. Patients reported a wide range of sexual difficulties. Preference assessment showed that more than 65% of patients were willing to undergo 6 months of chemotherapy for a 5% increase in likelihood of cancer cure.

CONCLUSION

Self-rated QOL in breast cancer patients 2 to 5 years following adjuvant therapy was generally favorable. Less than one third of patients reported moderate to severe symptoms. Selected aspects of sexual function appeared to be compromised. The majority of patients indicated a willingness to accept 6 months of chemotherapy for small to modest potential benefit.
Novel staging protocol for non-small-cell lung cancers according to MRP-1/CD9 and KAI1/CD82 gene expression.

PURPOSE

The transmembrane-4 superfamily (TM4SF) is a recently discovered family of genes. Of the TM4SF members, MRP-1/CD9, KAI1/CD82, and ME491/CD63 have been reported to modulate tumor progression or metastasis. In this study, we investigated the relationships between these three genes, MRP-1, KAI1, and ME491, in patients with non-small-cell lung cancers (NSCLCs). Moreover, we assessed the prognostic value of evaluating the expressions of MRP-1, KAI1, and ME491 simultaneously in NSCLCs.

PATIENTS AND METHODS

One hundred seventy-two patients up to stage IIIB NSCLC underwent radical surgery during the period of January 1991 through June 1994. Using a quantitative reverse-transcriptase polymerase chain reaction (RT-PCR) analysis, we studied the expression of MRP-1, KAI1, and ME491 genes in these patients.

RESULTS

We found that 109 patients (63.4%) had MRP-1-positive tumors and 42 patients (24.4%) had KAl1-positive tumors. Conversely, all 172 patients expressed ME491. No relationship was found between MRP-1 expression and KAI1 expression. We classified these patients into three groups. The 36 patients who were positive for both MRP-1 and KAI1 were defined as group A; the 79 patients with reduced expression of either MRP-1 or KAI1 were defined as group B, and the remaining 57 patients with reduced expression of both MRP-1 and KAI1 were defined as group C. This new classification was correlated with nodal status, tumor status, and pathologic stage (P = .0056, P = .0003, and P < .0001, respectively). In NSCLC patients, the 5-year survival rate of group A patients was significantly better than that of group B patients and much better than that of group C patients (86.8%, 53.9%, and 31.5%, respectively; P < .0001). Cox multivariate regression analysis showed that this new classification in NSCLCs was a significant prognostic factor, as was the nodal status (P < .0001).

CONCLUSION

Our results suggest that a low MRP-1 and KAI1 expression by tumors of the lung may be associated with poor prognosis. It is conceivable that the evaluation for MRP-1 and KAI1 expression may identify node-negative lung cancer patients who are at high risk for early disease recurrence, and thus need intensive adjuvant therapy.

PURPOSE

Plakoglobin is thought to play a key role in cadherin-mediated epithelial cell adhesion, because it is a common component of desmosomal and nondesmosomal adherens junctions. Because loss of homotypic cell adhesion is an important early step in invasion and metastasis of solid tumors, we evaluated the frequency and prognostic significance of a deficient expression of plakoglobin in human lung cancer.

PATIENTS AND METHODS

At primary surgery, representative specimens of the primary tumor were obtained from 96 consecutive patients with completely resected non-small-cell lung carcinoma (NSCLC) without overt distant metastases. Cryostat sections of these specimens and metastatic lymph nodes were stained with monoclonal antibody (mAb) PG 5.1 against plakoglobin, using an immunoperoxidase technique. Patients were monitored for a median of 39 months (range, 12 to 56) after surgery.

RESULTS

Absent or severely reduced expression of plakoglobin (ie, < 30% positive tumor cells) was observed in 39 patients (40.6%). There was no significant correlation to established risk factors, such as the histology, extension, and histologic grade of the primary tumor and metastatic lymph node involvement, or expression of alpha-catenin. Expression of plakoglobin in lymph node metastases ranged from 0% to greater than 60% positive tumor cells. Deficient plakoglobin expression on the primary tumor was significantly correlated to a shortened disease-free and overall survival in patients with adenocarcinomas, pT1-2 tumors, or negative lymph nodes (pN0). In patients with pT1-2 tumors, the independence of this prognostic influence from established risk factors was demonstrated by Cox regression analyses (disease-free survival, P = .002; overall survival, P = .038).

CONCLUSION

Deficient expression of plakoglobin appears to be an important event in the progression of NSCLC.
Is the survival of melanoma patients receiving polyvalent melanoma cell vaccine linked to the human leukocyte antigen phenotype of patients?

Published: February 2017

PURPOSE

An allogeneic polyvalent melanoma cell vaccine (PMCV) has been shown to be efficacious in improving overall survival of patients with malignant melanoma in a phase II clinical setting. The PMCV consists of three allogeneic melanoma cell lines. The objectives of the study were to determine (1) whether the survival of melanoma patients who received PMCV was related to the patient's human leukocyte antigen (HLA) class I phenotype matching the HLA class I phenotype of the PMCV, and (2) whether PMCV clinical efficacy was correlated to melanoma patients with a particular HLA phenotype(s).

MATERIALS AND METHODS

PMCV was given to 69 melanoma patients with American Joint Committee on Cancer (AJCC) stage I to IV disease status. The PMCV and patients lymphocytes were typed for HLA-A and -B. A correlation was made between the HLA expression of PMCV lines and the HLA of patients to their survival status. A second correlation was made between the HLA of patients and survival independent of the PMCV HLA phenotype.

RESULTS

Patients whose HLA phenotype (A3/11 and B7/44) matched the PMCV lines had a better overall survival (P < .029). Analysis of HLA expression of patients independent of PMCV HLA to survival showed that HLA-A25 phenotype patients had a significantly better overall survival (P = .006). HLA-B35 patients had a poorer survival outcome (P = .019).

CONCLUSION

The studies indicate that overall survival following PMCV treatment in melanoma patients significantly correlates with their HLA phenotypes. These correlations may be related to the host immune response to the PMCV or due to differences in the clinical course of melanoma in patients with different HLA types.
Fumagillin analog in the treatment of Kaposi's sarcoma: a phase I AIDS Clinical Trial Group study. AIDS Clinical Trial Group No. 215 Team.

Published: February 2017

PURPOSE

Angiogenesis is a major component of Kaposi's sarcoma (KS) and a critical process in tumor growth. The present study was designed primarily to test the toxicity and pharmacokinetics (PK) of the angiogenesis inhibitor TNP-470 and secondarily to evaluate tumor response in patients with early AIDS-related KS.

PATIENTS AND METHODS

Patients with AIDS-related KS were required to have cutaneous disease with > or = 5 measurable lesions and no evidence of pulmonary, symptomatic gastrointestinal, or acutely life-threatening KS. Thirty-eight patients received TNP-470 by weekly intravenous infusion over 1 hour at one of six dose levels for up to 24 weeks.

RESULTS

The dose levels tested included 10, 20, 30, 40, 50 and 70 mg/m2. Median CD4 count was 24 cells/microl (range, 0 to 460). Fourteen patients (36%) had > or = 50 cutaneous lesions and 19 (49%) had oral lesions. Adverse events included neutropenia (n = 2), hemorrhage (n = 3), and urticaria (n = 1). PK studies showed wide interpatient and intrapatient variability. Elimination half-life values were short (range, 0.01 to 0.61 hours). Seven patients (18%) achieved a partial response. The median time to partial response was 4 weeks (range, 2 to 25), and the median duration of response was 11 weeks (range, 3 to 26+).

CONCLUSION

TNP-470, administered as a weekly, 1-hour infusion to patients with early AIDS-KS is well-tolerated at doses up to and including the highest dose tested. Tumor responses were observed in a substantial number of cases and occurred at various dose levels. TNP-470 should be evaluated further in patients with AIDS-KS as a single agent and in combination with other biologic response modifiers in early disease or after initial response to cytotoxic chemotherapy.
