PURPOSE Pelvic radiation is standard treatment for women with stage IIb to IVa cervical cancer, but treatment results are disappointing, particularly for women with bulky tumors. We investigated the role of primary chemotherapy followed by pelvic radiotherapy in a randomized trial. PATIENTS AND METHODS Two hundred sixty patients with stage IIb and IVa cervical cancer received either standard pelvic radiotherapy or primary chemotherapy with cisplatin 60 mg/m2 and epirubicin 110 mg/m2 administered at 3-week intervals for three cycles, followed by pelvic radiotherapy. RESULTS Ninety-nine patients have relapsed with a median follow-up duration of 1.3 years; in 62 patients, the first site of progressive disease was the pelvis. Patients who received primary chemotherapy had a significantly higher pelvic failure rate than those who received radiotherapy alone (P < .003). Seventy-six patients have died, and those who received primary chemotherapy had significantly inferior survival compared with those who received radiotherapy alone (P = .02). Tumor response following chemotherapy was observed in 63%. After radiotherapy, tumor response occurred in 72% of those who received combined modality treatment, compared with 92% of those who received radiotherapy alone. CONCLUSION Primary chemotherapy with epirubicin and cisplatin, although resulting in tumor response in a significant proportion of patients, is accompanied by an inferior local control rate and survival compared with standard pelvic radiotherapy alone.

PURPOSE To determine the prognostic significance of a normal serum prostate-specific antigen (PSA) level in patients with prostatic cancer with long-term follow-up evaluation after radiotherapy. MATERIALS AND METHODS PSA information was available in 403 patients (38%) who were treated with pelvic lymph node dissection and retropubic radioactive iodine-125 implantation. One hundred eighty-two patients had a normal serum PSA level (< or = 4.0 ng/mL) the first time this test was conducted during the follow-up period, designated PSA-1. RESULTS Among patients with PSA-1 values < or = 1.0 ng/mL, the 5-year PSA relapse-free survival rate was 85% compared with 27%, respectively, among those with PSA values in the higher range of normal (P < .00001). Multivariate analysis demonstrated that only a PSA-1 value greater than 1.0 to < or 4.0 (P < .00001) and grade II/III histology (P = .009) had a negative impact on continued PSA relapse-free survival. The only independent variable identified by a multivariate analysis to affect local relapse-free survival (LRFS) was a PSA-1 value greater than 1.0 to < or = 4.0 ng/mL (P < .004), while high-grade histology (P < .0001) and local failure (P < .001) were the only significant variables to affect distant metastases-free survival (DMFS). CONCLUSION Patients with PSA values < or = 1.0 ng/mL are significantly less likely to have a subsequent relapse after therapy than those with levels greater than 1.0 to < or = 4.0 ng/mL. Continuously maintained PSA levels of < or = 1.0 ng/mL after treatment may serve as an end point for early evaluation of the efficacy of experimental radiotherapy protocols in prostate cancer.

PURPOSE This prospective, randomized trial was designed to determine if three cycles of cisplatin plus etoposide (PVP16) can produce therapeutic results comparable to three cycles of cisplatin, etoposide, and bleomycin (PVP16B) in patients with disseminated germ cell tumors. PATIENTS AND METHODS One hundred seventy-eight patients with minimal- or moderate-stage disease (Indiana staging system) were randomized to receive cisplatin (20 mg/m2 on days 1 to 5) plus etoposide (100 mg/m2 on days 1 to 5) with or without weekly bleomycin (30 IU/wk for 9 consecutive weeks). Following three cycles of chemotherapy over 9 weeks, patients with residual radiographic disease underwent surgical resection. If persistent carcinoma was noted, two additional 3-week courses of chemotherapy were administered. RESULTS One hundred seventy-one patients were fully assessable for response and survival. The two treatment groups were similar with respect to patient characteristics. The toxicities were comparable between the two arms. No clinically significant incidence of pulmonary toxicity occurred with PVP16B. Overall, 81 of 86 patients (94%) who received PVP16B and 75 of 85 patients (88%) who received PVP16 achieved a disease-free status with chemotherapy and/or surgery. However, greater numbers of treatment failures, including persistent carcinoma in postchemotherapy resected residual disease and relapses from complete remission, occurred on the arm without bleomycin (overall adverse outcome, P = .004). The failure-free (86% v 69%; P = .01) and overall survival (95% v 86%; P = .01) rates were inferior on the PVP16 arm. CONCLUSION Bleomycin is an essential component of PVP16B therapy in patients who receive three cycles of treatment for minimal- or moderate-stage disseminated germ cell tumors.

PURPOSE In a phase II multiinstitutional outpatient trial, patients with progressive metastatic renal cell carcinoma were treated with a combination of subcutaneous (SC) recombinant interleukin-2 (rIL-2) and recombinant interferon alfa-2 (rIFN alpha 2). PATIENTS AND METHODS One hundred fifty-two patients with metastatic renal cell carcinoma were treated. Treatment courses consisted of SC rIL-2 at 20 x 10(6) IU/m2 three times per week in weeks 1 and 4, and at 5 x 10(6) IU/m2 three times per week in weeks 2, 3, 5, and 6. Additionally, patients received SC rIFN alpha 2 6 x 10(6) U/m2 once per week in weeks 1 and 4, and three times per week in weeks 2, 3, 5, and 6. RESULTS There were nine (6%) complete responses (CRs) and 29 (19%) partial responses (PRs), for an overall response rate of 25% (95% confidence interval, 19% to 32%). The median duration of responses for CRs and PRs was 16+ and 9 months, respectively. Additionally, 55 patients (36%) had stable disease (SD). Fifty-nine patients (39%) had continued disease progression (PD) despite treatment, or went off study after less than 4 weeks of therapy. The majority of patients treated experienced fever, chills, malaise, nausea, vomiting, and anorexia, side effects that were mostly limited to World Health Organization (WHO) grade 1 and 2. However, one patient developed grade 4 CNS toxicity with extended somnolence. On cessation of therapy, the neurologic symptoms in this patient were fully reversible, with no neurologic deficiency. CONCLUSION In summary, this multiinstitutional home-therapy setting of SC rIL-2 and SC rIFN alpha 2 in patients with progressive metastatic renal cell carcinoma demonstrated drastically reduced systemic toxicity, while it confirmed the therapeutic efficacy of the low-dose SC immunotherapy combination schedule.

PURPOSE To evaluate a high-dose chemotherapy regimen without total-body irradiation (TBI) followed by allogeneic (allo) bone marrow transplantation (BMT) in patients with lymphoid malignancies who had received prior dose-limiting radiotherapy. PATIENTS AND METHODS Fifty-six patients with non-Hodgkin's lymphoma (NHL, n = 26), Hodgkin's disease (HD, n = 17), or acute lymphoblastic leukemia (ALL, n = 13) with a history of previous radiation therapy were treated with cyclophosphamide (7.2 g/m2), carmustine (300 mg/m2 or 600 mg/m2), and etoposide (2,400 mg/m2; CBV) followed by allo BMT. RESULTS Nine of 56 patients are alive and disease-free a median of 1,091 (range, 512 to 1,784) days post-transplant. The probabilities of transplant-related mortality, relapse, and event-free survival at 2 years for the entire group of 56 patients were .62, .59, and .17, respectively. Patients who received 600 mg/m2 of carmustine had a higher incidence of grade 3 or 4 regimen-related toxicities (RRTs) (14 of 22) than did patients who received 300 mg/m2 (12 of 33; P < .04), whereas there was no difference in relapse (.34 and .53, respectively, P = .73). Fourteen of 16 patients who received allo BMT for advanced disease (n = 12) or less-advanced disease (n = 4) but who were also eligible for auto BMT relapsed (n = 4) or died of transplant-related complications (n = 10). CONCLUSIONS Allo BMT following a high-dose CBV regimen resulted in long-term disease-free survival in 17% of patients with lymphoid malignancies who had received prior dose-limiting radiotherapy. A high incidence of transplant-related complications, especially fatal idiopathic pneumonia syndrome (IPS) and a high relapse rate limited success. Morbidity and mortality associated with carmustine 600 mg/m2 were high and were not associated with a decrease in relapse. The number of patients in this study eligible for either allo or auto BMT was limited and precluded meaningful analysis of relative effectiveness.

Published: February 2017

PURPOSE Intracavitary (IC) delivery of cisplatin (CDDP) has been used in the treatment of a variety of adult malignancies based on the favorable pharmacokinetics obtained locally. Since IC CDDP has not been reported in children, we studied its use in a group of pediatric patients with regard to safety, toxicity, pharmacokinetics, and responses. PATIENTS AND METHODS Eleven patients with an age range of 8 months to 21 years with diagnoses of rhabdomyosarcoma (n = 5), pleuropulmonary blastoma (n = 2), osteosarcoma (n = 2), Ewing's sarcoma (n = 1), and malignant rhabdoid tumor of the kidney (n = 1) were studied. Eight patients received intrapleural (IPL) CDDP and three received intraperitoneal (IP) CDDP, either at diagnosis (n = 3) or relapse (n = 8), for malignant pleural effusion (n = 3), malignant ascites (n = 2), pleural-based tumor (n = 4), pulmonary metastases (n = 1), or abdominal tumor spillage (n = 1). RESULTS IC CDDP was well tolerated by pediatric patients. Two patients experienced a transient increase in serum creatinine levels (> two times baseline) and two patients experienced severe neutropenia (absolute neutrophil count < 500/microL). Pharmacokinectic measurements showed a 40-fold advantage for the pleural cavity versus serum after IPL CDDP and serum levels comparable to those achieved with systemic administration of CDDP. Four of five patients who received IC CDDP for malignant ascites or pleural effusion had at least a temporary response. Only three of 11 patients studied had local recurrences following IC CDDP. There are currently four survivors in the study group, including two long-term survivors at greater than 8 years since IPL CDDP treatment. CONCLUSION The safety, toxicity, and pharmacokinetics of IC CDDP in pediatric patients are similar to that reported in adult patients. The low incidence of local recurrence following IC CDDP in this group of largely relapsed patients suggests that further study of IC CDDP for pediatric patients is warranted.

Published: February 2017

PURPOSE To determine if variability in toxicity of amonafide during phase II trials could be correlated with pharmacokinetic variability. PATIENTS AND METHODS Seventy-three patients enrolled onto three Cancer and Leukemia Group B (CALGB) phase II trials of amonafide (300 mg/m2 daily for 5 days) were studied, using a limited sampling strategy (45 minutes and 24 hours) to estimate the amonafide area under the plasma concentration-time curve (AUC). Concentrations of N-acetyl-amonafide, an active metabolite, were also determined. RESULTS The primary determinant of toxicity at a fixed dose of amonafide was the extent of N-acetylation. Fast acetylators (36% of patients) had significantly greater toxicity than slow acetylators (64% of patients), with median WBC nadirs of 500/microL and 3,400/microL, respectively (P < or = .001). In a multivariate analysis, lower pretreatment WBC count, lower albumin level, and nonwhite race were also independently associated with toxicity. Further analysis of interracial differences demonstrated that minority women had slower clearance of amonafide (P = .026) and a higher incidence of grade 4 leukopenia (P = .042). CONCLUSION The highly variable toxicity of amonafide is primarily due to genetic differences in N-acetylation. Other genetic (race) and acquired factors (baseline WBC count and albumin level) also appear to influence the extent of toxicity observed following administration of this agent.
Clinical importance of the determination of tumor angiogenesis in breast carcinoma: much more than a new prognostic tool.
Authors: Gasparini G , Harris A L 
Published: February 2017

PURPOSE To review prognostic and therapeutic applications of angiogenesis research in breast carcinoma. METHODS We reviewed the (1) biologic role of angiogenesis, particularly in transformation, progression, and metastasis of breast cancer; (2) methods to detect angiogenic activity in human pathology; (3) clinical studies relating clinical outcome of patients with breast cancer to the assessment of angiogenesis; (4) predictive value of angiogenesis for response to anticancer therapies; and (5) pharmacologic characteristics of current antiangiogenic drugs. RESULTS There is mounting evidence that angiogenesis plays a relevant role in the biologic aggressiveness of breast cancer. Using either immunohistochemical or biochemical methods, several studies have shown a worse prognosis for those patients with tumors with high angiogenic activity. In some studies angiogenesis has an independent prognostic value. The most promising angiogenic inhibitors are under early-phase clinical evaluation in patients with tumors resistant to conventional therapies. Novel therapeutic strategies for breast cancer patients are presented and discussed. CONCLUSION The majority of the retrospective studies show that angiogenesis is an important new prognostic indicator in early-stage breast carcinoma. This marker should be evaluated in prospective controlled clinical trials to demonstrate whether adjuvant therapies may improve the prognosis of those patients at high risk, eg, those with highly vascularized tumors. Since invasive breast carcinoma has a well defined stromal vascular component and produces angiogenic factors, it seems reasonable to postulate that this tumor may be one of the most responsive to angiogenesis inhibitors given alone or in combination with conventional anticancer treatments.
Ovarian cancer screening.
Authors: Mackey S E , Creasman W T 
Published: February 2017

PURPOSE To review potential screening tools of early ovarian cancer and the associated risk factors for the development of ovarian carcinoma. DESIGN AND RESULTS A review of pertinent literature was conducted, restricted to English-language published reports, book chapters, and articles. The value of serum tumor markers, particularly CA 125, ultrasound, transabdominal and transvaginal ultrasonography, and transvaginal color Doppler imaging as screening tools for ovarian cancer was assessed. CONCLUSION Based on the literature, a large-scale long-term study that compares the mortality rates of a screened versus unscreened patient population is required before the efficacy of any screening method can be determined definitively.

PURPOSE The aim of this double-blind, double-dummy, crossover study was to compare the efficacy, tolerability, and time of onset of analgesia after the administration of 10 mg of morphine hydrochloride via the oral and rectal routes in opioid-naive cancer patients with pain. PATIENTS AND METHODS Thirty-four patients with cancer pain and no previous opioid treatment were randomized to receive morphine hydrochloride 10 mg orally or rectally (in the form of a microenema) for 2 days. During days 3 and 4, a crossover took place. The scores of pain, nausea, and sedation (visual analog scale of 0 to 100) calculated as the percentage change from baseline (before opioid administration) were assessed at different intervals up to 240 minutes. The number of vomiting episodes was recorded. Parity tests and analysis of variance (ANOVA) were performed to compare the two administration routes. RESULTS A significant difference in pain intensity was achieved 10 minutes after rectal administration compared with 60 minutes after oral administration. There was still a significant reduction in pain via the rectal route after 180 minutes versus via the oral route after 120 minutes. No significant difference was observed in the intensity of sedation, nausea, or number of vomiting episodes between the oral and rectal routes. CONCLUSION A liquid solution of morphine is well absorbed via the rectal route. Rectal morphine is safe, effective, easy to manage, and inexpensive, with a rapid onset of action. Rectal morphine can be considered a valid alternative route for opioid administration and may also be used when rescue doses of morphine are required in patients regularly treated with oral or parenteral opioids.
p53 in node-negative breast carcinoma: an immunohistochemical study of epidemiologic risk factors, histologic features, and prognosis.

Published: February 2017

PURPOSE The present study explores p53 in relation to the following four aspects of node-negative breast carcinoma: epidemiologic risk factors, tumor histopathology, prognosis, and HER2/neu (HER) expression. MATERIALS AND METHODS Immunohistochemical (IH) staining for p53 was performed on formaldehyde-fixed, paraffin-embedded primary invasive carcinomas from 440 node-negative patients with a median follow-up duration of 119 months. RESULTS The IH expression, or lack thereof, of p53 separately or in combination with HER did not prove to be prognostically significant and there was no consistent association of p53 with epidemiologic risk factors. p53 was expressed in 68% of medullary carcinomas (MEDs), which is a significantly higher frequency (P < .001) than in lobular (9%) and duct (23%) carcinomas. p53 was not found in some types of low-grade carcinomas (tubular and papillary), and was observed in a minority of mucinous carcinomas. p53 was present significantly more often in carcinomas with high-grade or poorly differentiated nuclear grade than in low- or intermediate-grade tumors. There was an inverse statistically significant relationship between estrogen receptor (ER) positivity and p53 expression. Tumors with the p53(+)/HER(-) immunophenotype tended to be MEDs or duct carcinomas with a marked lymphoplasmacytic reaction. Infiltrating lobular carcinomas (IFLCs) were largely p53(-)/HER(-). p53(+)/HER(+) carcinomas had the best prognosis. The poorest outcome was associated with the p53(-)/HER(+) immunophenotype. This trend was statistically significant for recurrence-free and overall survival in patients with T1NOMO infiltrating duct carcinoma (IFDC). CONCLUSION The IH demonstration of p53 was not a reliable prognostic indicator in the node-negative breast carcinoma patients studied and it was not associated with major epidemiologic risk factors. The combined immunophenotypic expression of p53 and HER was significantly associated with some histologic types of breast carcinoma and with prognosis in T1NOMO breast carcinoma.

PURPOSE To compare 1 year of therapy with continuous cyclophosphamide, methotrexate, fluorouracil (5-FU), vincristine, and prednisone (CMFVP) with a short course of treatment with a doxorubicin-based regimen in the postsurgical adjuvant treatment of patients with hormone receptor-negative, node-positive breast cancer. PATIENTS AND METHODS Five-hundred thirty-one eligible women with hormone receptor-negative, node-positive breast cancer were randomized to receive either 1 year of therapy with CMFVP or 20 weeks of therapy with four 5-week courses of treatment with 5-FU, doxorubicin, cyclophosphamide, and methotrexate (FAC-M). RESULTS At a median follow-up time of 4.9 years, the two treatment arms cannot be demonstrated to be different with respect to overall survival (stratified log-rank, P = .27). The 5-year survival rate is 64% on the CMFVP arm and 61% on the FAC-M arm. CMFVP produces marginally superior disease-free survival (P = .06). The estimated 5-year disease-free survival rate is 55% for patients treated with CMFVP as opposed to 50% for patients treated with FAC-M. CONCLUSION Neither regimen was shown to be superior in terms of overall survival. Because the disease-free survival produced by CMFVP is marginally superior to that produced by FAC-M, we do not recommend FAC-M for further investigation or for routine use. Possible implications of this study are discussed in the context of other adjuvant chemotherapy trials.
