Published: February 2017

PURPOSE To determine the prevalence and severity of vasomotor, gynecologic, and other symptoms among breast cancer patients, their health concerns, beliefs about estrogen replacement therapy (ERT), and willingness to take estrogen under medical supervision. MATERIALS AND METHODS A questionnaire was mailed to 320 women aged 40 to 65 years and diagnosed with in situ or invasive locoregional breast cancer in the years 1988 to 1992. RESULTS Of 222 eligible respondents, 190 were postmenopausal. The prevalence of symptoms among the postmenopausal women was as follows: hot flashes, 65%; night sweats, 44%; vaginal dryness, 48%; dyspareunia, 26%; difficulty sleeping, 44%; and feeling depressed, 44%. The latter two symptoms increased in frequency with increasing severity of vasomotor symptoms (P for trend < or = .001). Forty-one percent of menopausal women perceived that they had experienced, since their breast cancer diagnosis, a physical or emotional problem related to menopause. Of these women, 50% felt they needed treatment. Overall, 31% of postmenopausal women would consider taking estrogen. Those who perceived that they had experienced a menopausal problem were more likely to consider estrogen than those who did not (42% v 22%, P = .003). The proportions willing to take estrogen increased with increasing severity of symptoms, particularly feelings of depression and sleep disturbance (P for trend = .008 and .007, respectively). Awareness that estrogen decreases the risks of heart disease and osteoporosis was not associated with an increased willingness to take it. However, beliefs that estrogen increases the risks of recurrent breast cancer and uterine cancer were associated with a decreased willingness to take it (P = .003 and .08, respectively). CONCLUSION Vasomotor symptoms have a significant impact on the quality of life of breast cancer patients. Clinical trials to determine the safest and the most effective ways to relieve these symptoms are needed.

PURPOSE To evaluate the effectiveness of combined intraoperative radiation therapy (IORT) and perioperative chemotherapy in the management of unresectable pancreatic cancer. MATERIALS AND METHODS Forty-nine patients with localized unresectable adenocarcinoma of the pancreas were treated in a multimodality program of initial IORT and perioperative chemotherapy (fluorouracil [5-FU]/leucovorin) followed by combined external-beam radiation (40 to 55 Gy) and continued chemotherapy. Patients were evaluated for toxicity, pattern of failure, and survival. The follow-up times of these patients range from a minimum of 12 months to a maximum of 62 months, with a median of 28 months. RESULTS The incidence of perioperative mortality was 0%. Early postsurgical morbidity (grade 3/4) was observed in seven of 49 patients (14%) and late treatment-related morbidity (grade 3/4) in eight of 43 patients (19%) alive beyond 6 months. Morbidity was primarily gastrointestinal (GI), with no hematologic toxicities observed. The median survival time in the total group of patients is 16 months, with a 2-year survival rate of 22% and a 4-year survival rate of 7%. Freedom from local progression of disease was achieved in 71% of patients. CONCLUSION The patients who undergo IORT with electrons and treated with perioperative chemotherapy (5-FU leucovorin) followed by additional external-beam radiation and chemotherapy appear to have improved survival, with few early or late complications. Dose escalation of external-beam radiation and chemotherapy may further improve local control of disease and survival of patients.

PURPOSE This study was designed to define the maximum-tolerated dose (MTD) and pharmacology of paclitaxel administered by the intraperitoneal (IP) route on a weekly schedule. PATIENTS AND METHODS Thirty-three patients with residual ovarian cancer following standard chemotherapy were entered onto this phase I trial. Patients were treated weekly with IP paclitaxel administered in 2 L of normal saline following premedication. Patients with nonassessable disease received 16 weekly courses. The initial dose level was 20 mg/m2/wk. There was no intrapatient dose escalation. RESULTS Multiple grade 2 toxicities were observed at the 75-mg/m2/wk dose level. These toxicities included abdominal pain, nausea, vomiting, leukopenia, and fatigue. One episode of grade 4 vomiting thought to be secondary to a transient partial small-bowel obstruction occurred at this dose level. At dose levels > or = 60 to 65 mg/m2, pharmacology studies documented the persistence of significant IP paclitaxel levels 1 week after drug administration, suggesting very slow peritoneal clearance and continuous exposure of the peritoneal cavity to active concentrations of paclitaxel. Low plasma paclitaxel concentrations were detected in the majority of patients treated at dose levels > or = 55 mg/m2. CONCLUSION Paclitaxel can be delivered by the IP route on a weekly schedule with both an acceptable toxicity profile and a major pharmacokinetic advantage for cavity exposure. The recommended dose and schedule for phase II study of IP paclitaxel is 60 to 65 mg/m2 weekly.
Bone marrow involvement in Hodgkin's disease: an analysis of 135 consecutive cases. German Hodgkin's Lymphoma Study Group.

Published: February 2017

PURPOSE To describe the incidence of primary bone marrow involvement (BMI) in Hodgkin's disease (HD) and its correlation with clinical and laboratory features present at diagnosis, and to evaluate the prognostic relevance of BMI. PATIENTS AND METHODS Between 1983 and 1991, 2,307 patients with HD were treated according to two trial generations (HD1-3 and HD4-6) of the German Hodgkin's Lymphoma Study Group (GHSG). RESULTS One hundred thirty-five cases of primary BMI were observed. The incidence of BMI was 4.8% in the HD4-6 study generation, which included all stages. Among stage IV patients, 32% had BMI. Among those with BMI, other organs were also involved in 33%. Among all patients, the presence of BMI was significantly associated with B symptoms, lymph nodes on both sides of the diaphragm, mixed cellularity histologic subtype, leukocytopenia, anemia, thrombocytopenia, lactate dehydrogenase (LDH) level more than 400 U/L, and erythrocyte sedimentation rate (ESR) more than 40 mm/h. BMI was negatively correlated with a large mediastinal tumor (3.7% v 20.0% in non-BMI cases). Eighty-seven of 108 (81%) assessable patients with BMI achieved a complete remission (CR). This compares favorably with the overall CR rate in all stage IIIB/IV patients. Among stage IV patients, BMI has no prognostic relevance with regard to freedom from treatment failure and overall survival. Twenty-one patients with BMI relapsed after having achieved a CR. Only five of these (24%) again had a positive bone marrow biopsy. CONCLUSION The prognosis of patients with BMI is not worse than the prognosis of other advanced-stage HD patients. BMI alone does not define a special high-risk group in which a different treatment approach is indicated.

PURPOSE To determine if a rapid 3H-uridine uptake assay using breast tumor cells from biopsy specimens could predict clinical response to fluorouracil (5FU) in patients with metastatic breast cancer. PATIENTS AND METHODS A double-blind prospective study was conducted of 60 patients with measurable, metastatic breast cancer who had failed to respond to at least one prior chemotherapy regimen. Patients received 5FU 300 mg/m2/d by continuous infusion and were monitored for response. Tumor cells from biopsy specimens were grown in microwells and exposed for 3 days to 0.1, 1.0, 10.0, and 100.00 micrograms/mL of 5FU on strips coated with drug and extracellular matrix. Cells were pulsed with 3H-uridine overnight. Incorporated radioactivity was compared for wells with and without drug. Results were available 4 days from specimen submission. RESULTS Of 45 eligible patients, 11 (24%) were not assessable in vitro. Nine patients were assessable in vitro, but not clinically. Of the remaining 25 patients, who were assessable both clinically and in vitro, there was one complete response (CR), five partial responses (PRs), five cases of stable disease, and 14 cases of progressive disease, for an objective response rate of 24%. Response in vitro was significantly correlated with clinical response (P = .002). Of six clinical responders, five also responded in vitro, for an assay sensitivity of 83%. Of 19 nonresponders, 17 were nonresponders in vitro, for a specificity of 89%. The positive predictive value of the test was 71% (five of seven), and the negative predictive value was 94% (17 of 18). CONCLUSION Results of an in vitro assay were significantly correlated with clinical response in patients with metastatic breast cancer treated with continuous infusion 5FU.

PURPOSE To investigate the efficacy of continuous infusion fluorouracil (5FU) with every-3-week epirubicin and cisplatin (ECF) as primary chemotherapy instead of immediate mastectomy for patients with large, potentially operable, breast cancer. PATIENTS AND METHODS Fifty patients with large operable breast cancer, median tumor diameter 6 cm (range, 3 to 12), were treated with 5FU 200 mg/m2/d via a Hickman line using an ambulatory pump for 6 months with epirubicin 50 mg/m2 intravenously (IV) and cisplatin 60 mg/m2 IV every 3 weeks for eight courses. Subsequent surgery and/or radiotherapy was determined by clinical response. RESULTS Forty-nine patients achieved an overall response (98%; 95% confidence interval [CI], 94% to 100%), including 33 complete clinical remissions (CRs) (66%; 95% CI, 53% to 79%). Only three patients (6%) still required mastectomy. Tumor cellularity was markedly reduced on repeat needle biopsy following 3 weeks of treatment in 81% of patients versus only 36% in similar patients after conventional chemotherapy (P < .002). Severe (World Health Organization [WHO] grade 3 to 4) toxicity was rare, with nausea/vomiting being the most common, occurring in 20% of patients. CONCLUSION Primary infusional ECF appears to be more active on clinical and histopathologic grounds than conventional chemotherapy for large operable breast cancer and is well tolerated. This approach now merits randomized comparison to determine if high CR rates may translate into improved survival.

PURPOSE The mechanisms of antitumor activity, clinical pharmacology, toxicity, and efficacy of tamoxifen in women with early and advanced breast cancer and the drug's potential role in prevention of breast cancer were reviewed. DESIGN A comprehensive review of the literature from 1966 to 1994 was conducted; reports were identified using the Cancerline and Medline data bases. RESULTS The cellular actions of tamoxifen are not completely understood, but it appears that the drug's antiproliferative effects are mediated primarily by inhibition of the activities of estrogen through binding to estrogen receptors (ERs). Disease-free and overall survival rates have been increased in postmenopausal women with ER-positive tumors when tamoxifen has been used as adjuvant therapy (irrespective of nodal status). In premenopausal women, adjuvant therapy with tamoxifen has been associated with prolongation of disease-free survival, but its impact on survival remains to be defined. Tamoxifen is the initial hormonal treatment of choice in both premenopausal and postmenopausal women with ER-positive metastatic disease. Retrospective review of adjuvant therapy studies showed an approximately 39% reduction in the incidence of contralateral primary breast carcinoma in tamoxifen-treated women, which indicates that tamoxifen could have a role in breast cancer prevention. CONCLUSION The use of tamoxifen has resulted in a substantial modification of breast cancer's natural history, particularly in postmenopausal women. Ongoing clinical trials will examine the effects of tamoxifen therapy on lipids, coagulation proteins, bone, and endometrium, and its effectiveness as an agent in the prevention of breast cancer.

PURPOSE We initiated a large multicenter phase II trial in stage IV non-small-cell lung cancer (NSCLC) to evaluate the activity and safety of an oral gelatin-based formation of vinorelbine. PATIENTS AND METHODS Twenty-three centers participated in this uncontrolled phase II study, which accrued patients between August 1991 and March 1992. Eligible patients had previously untreated measurable or assessable stage IV NSCLC, age more than 18 years, and Karnofsky performance status > or = 70%. The treatment plan initially was to administer 100 mg/m2/wk of oral vinorelbine or 80 mg/m2/wk for patients who had received prior radiation therapy. After the observation of grade IV granulocytopenia in six of the first 25 patients, subsequent doses were reduced by 40 mg (one capsule) in all patients. RESULTS One hundred sixty-two patients were treated: 138 with measurable and 24 with assessable disease. One hundred two patients were men and 60 women. The mean age was 62 years (range, 36 to 83). The overall response rate was 14.5% for patients with measurable disease (95% confidence interval, 9.3% to 21.7%). The median time to treatment failure (TTF) for all patients was 9 weeks. The median survival time was 29 weeks; the 1-year survival rate was 22%. Toxicities included grade 3 or 4 neutropenia in 40%, which was dependent on the vinorelbine dose. Other toxicities included mild to moderate nausea/vomiting, diarrhea, and stomatitis. The mean dose intensity of vinorelbine was 53 mg/m2. CONCLUSION Oral vinorelbine administered once weekly is an active agent in stage IV NSCLC. The median survival time of 29 weeks is similar to that achieved with single-agent intravenous vinorelbine and more aggressive cisplatin-based combinations. Further studies of this compound in the palliative-intent care setting appear to be indicated.

PURPOSE We conducted a phase II study to determine the response to and toxicity of docetaxel (Taxotere; Rhône-Poulenc Rorer Pharmaceuticals, Inc, Collegeville, PA) in patients with advanced non-small-cell lung cancer refractory to prior platinum-containing chemotherapy (PCC) regimens. PATIENTS AND METHODS Forty-four patients with stage IIIb or IV platinum-refractory non-small-cell lung cancer were treated with 100 mg/m2 of docetaxel intravenously over 1 hour every 3 weeks. The responses of 42 of 44 patients were assessable. Most patients had a Zubrod performance status of 1; the predominant histologic type was adenocarcinoma (61%), and 91% of patients had stage IV disease. RESULTS Nine of 42 assessable patients (21%) achieved a partial response to treatment. The median response duration (from response to progression) was 17 weeks, and the projected median survival duration of all patients is 42 weeks (51 weeks for adenocarcinoma and 22 weeks for nonadenocarcinoma). Grade 3/4 neutropenia occurred in 85% of patients and was associated with fever that required intravenous antibiotics in 16% of patients (3% of cycles). Other acute side effects included easily treated hypersensitivity reactions and dermatitis. Cumulative side effects included fluid retention and neuropathy. CONCLUSION Docetaxel administered at 100 mg/m2 intravenously every 3 weeks has notable activity against platinum-refractory non-small-cell lung cancer, with a 21% major response rate. Primary side effects were neutropenia, hypersensitivity, and fluid retention.

Published: February 2017

PURPOSE AND METHODS We evaluated, in 1,800 patients with node-negative tumors treated with locoregional therapy until relapse, the competitive risks for different types of metastasis by cell proliferation (3H-thymidine labeling index [3H-dT LI]), estrogen receptors (ERs), and progesterone receptors (PgRs), and by the integration of biologic and clinicopathologic information. RESULTS Hormone receptor status and proliferative activity of the primary tumor were not indicative of contralateral failures. Hormone receptors failed to predict the 8-year incidence of locoregional recurrence, but they were significant indicators of distant metastasis and overall survival. The latter finding was confirmed even in multivariate analysis. Conversely, cell proliferation predicted both locoregional and distant metastases and survival, regardless of patient age, tumor size, and ER and PgR status. Recursive partitioning and amalgamation analysis ascribed to cell proliferation an important prognostic role for locoregional recurrence together with patient age and tumor size. CONCLUSION Biologic markers, in particular cell proliferation, provide information for the different types of relapse and could complement the predictive role of pathologic staging.

PURPOSE To correlate the presence of p53 mutations and initial characteristics, response to chemotherapy, and survival in newly diagnosed Burkitt's lymphoma (BL) and Burkitt's acute lymphoblastic leukemia (L3 ALL). PATIENTS AND METHODS Forty-eight patients with newly diagnosed BL or L3 ALL, most of whom were treated with very intensive regimens, including early CNS disease treatment, were studied. Detection of p53 mutations was made by single-strand conformation polymorphism (SSCP) analysis of exons 5 to 8 of the gene, and mutations were determined by direct sequencing of exons with abnormal SSCP findings. Comparison of outcome between mutated and nonmutated cases was made in all patients and also after excluding five patients who received therapeutic regimens considered as suboptimal and one patient who died of AIDS while in complete remission (CR), as those six patients had no p53 mutations. RESULTS A point mutation was found in nine patients (19%), and consisted of a missense mutation in seven and a chain-terminating mutation in two. SSCP, sequence, and cytogenetic analysis strongly suggested that eight of nine patients with mutations had retained the normal p53 allele, which had been lost in the remaining patient. These findings were confirmed by fluorescence-in-situ hybridization (FISH) with a p53-specific probe in two patients, including the one who had lost the normal p53 allele. Unexpectedly, mutations were significantly less frequent in patients with disseminated disease, ie, L3 ALL or stage IV BL (four of 35, 11%), than in more localized forms, ie, BL stage I, II, or III (five of 13, 38%) (P = .03). CR rates were similar in mutated (78%) and nonmutated cases (78%). The actuarial disease-free interval (DFI) after 12 months and actuarial survival rates after 24 months were 49% and 66%, respectively, in patients with mutations, and 73% and 48%, respectively, those without mutations. The differences were not significant. CONCLUSION Our findings suggest that, contrary to what is seen in most other neoplasias, p53 mutations in newly diagnosed BL and L3 ALL are not associated with extensive tumor mass or poor response to intensive therapeutic regimens. It is hypothesized that this difference with most tumors could be due to the fact that p53 mutations in BL and L3 ALL are generally associated with persistence of a normal residual p53 allele, contrary to what is observed in the majority of tumors.

PURPOSE Cladribine (2-CdA), a purine analog resistant to adenosine deaminase, has significant activity in a variety of lymphoproliferative diseases. This study was designed to determine the efficacy of 2-CdA in patients with relapsed or refractory chronic lymphocytic leukemia (CLL). PATIENTS AND METHODS Twenty-six patients aged 40 to 88 years (median, 64) who either had relapsed after an initial response or were refractory to conventional chemotherapy with at least an alkylating agent were treated with 2-CdA 0.1 mg/kg/d by continuous intravenous infusion for either 5 or 7 days every 28 days for a maximum of six cycles. RESULTS No complete remissions (CRs) occurred. Eight of 26 patients (31%) achieved a partial remission (PR). The actuarial median time to progression (TTF) in responding patients is 16 months (range, 6 to 22). The actuarial median survival duration of the responding patients is 12 months (range, 8 to 28). Eight of 26 patients (31%) sustained early toxicity. Seven of these eight patients died before the first reevaluation of infection (n = 3), pericardial tamponade (n = 1), Stevens-Johnson syndrome (n = 1), and stroke (n = 2). No nausea, emesis, alopecia, or renal, hepatic, or cardiac toxicity was observed. CONCLUSION 2-CdA has activity in patients with relapsed or refractory CLL. However, patients who have received multiple prior regimens that included fludarabine are less likely to respond, and there can be significant morbidity. Treatment of patients with less prior therapy earlier in the natural history of the disease may lead to improved and more durable responses.
