A phase 2 study of pegylated liposomal doxorubicin, bortezomib, dexamethasone and lenalidomide for patients with relapsed/refractory multiple myeloma.

Our previous studies have shown that lowering the dose of pegylated liposomal doxorubicin (PLD) and bortezomib in combination with intravenous dexamethasone on a longer 4-week cycle maintained efficacy and improved tolerability in both previously untreated and relapsed/refractory (R/R) multiple myeloma (MM) patients. Lenalidomide has shown efficacy in combination with bortezomib and dexamethasone but this combination has been poorly tolerated. We conducted this phase 2 study (clinicaltrials.gov identifier: NCT01160484) to evaluate whether a longer 4-week schedule using modified doses and schedules of IV dexamethasone (40 mg), bortezomib (1.0 mg/m(2)) and PLD (4.0 mg/m(2)) administered on days 1, 4, 8, and 11 with lenalidomide 10 mg daily on days 1-14 (DVD-R) would be effective and tolerated for patients with R/R MM. A total of 40 heavily pretreated patients were enrolled and 84.6% showed clinical benefit (complete response, 20.5%; very good partial response, 10.3%; partial response, 17.9%; minimal response, 35.9%) to the combination regimen. An additional 10.3% showed stable disease and 5.1% progressed while on study. The regimen was well tolerated, with a low incidence of adverse events such as fatigue (40%), thrombocytopenia (35%), neutropenia (35%), anemia (30%), peripheral neuropathy (25%) and pneumonia (15%). Thus, the DVD-R regimen is well tolerated and produces high response rates for patients with R/R MM.

Overexpression of p53 protein and outcome of patients treated with chemoradiation for carcinoma of the anal canal: a report of randomized trial RTOG 87-04. Radiation Therapy Oncology Group.

BACKGROUND: Despite encouraging results with chemoradiation as the primary means of managing carcinoma of the anal canal, approximately 20% of patients will develop a local recurrence. This study examined the prognostic significance of p53 nuclear protein overexpression in the pretreatment biopsies of patients treated with chemoradiation for epidermoid carcinoma of the anal canal. METHODS: All patients were treated in a prospective, randomized Radiation Therapy Oncology Group trial (RTOG 87-04) in which radiotherapy to the pelvis was compared with concurrent 5-fluorouracil (5-FU) or 5-FU and mitomycin-C. Formalin fixed, paraffin embedded blocks or unstained slides from the pretreatment biopsies of 64 patients were obtained from referring institutions and evaluated immunohistochemically with the polyclonal p53 antibody CM-1. A multivariate analysis was conducted to analyze overexpression of p53 in terms of locoregional control, no evidence of disease (NED), and overall survival. RESULTS: p53 protein was overexpressed in 48.4% of the cases. Although not statistically significant, there was a trend for patients whose tumors overexpressed p53 to have inferior locoregional control (52% vs. 72%, P = 0.13), NED survival (52% vs. 68%, P = 0.27), and absolute survival (58% vs. 78%, P = 0.14). Of all the pretreatment factors analyzed, only International Union Against Cancer stage was predictive of outcome in multivariate analysis. Among those patients whose tumors overexpressed p53, there was a trend toward improved outcome in the arm that received 5-FU and mitomycin-C compared with the arm that received 5-FU only. CONCLUSIONS: Overexpression of the p53 protein may be associated with inferior outcome for patients managed with definitive chemoradiation for epidermoid carcinoma of the anal canal.

Survival results among patients with alpha-fetoprotein-positive, unresectable hepatocellular carcinoma: analysis of three sequential treatments of the RTOG and Johns Hopkins Oncology Center.

PURPOSE: To analyze the observed therapeutic impact of the post-induction components of three treatment programs utilized sequentially between 1983 and 1991 for patients with unresectable alpha-fetoprotein-positive hepatoma. METHODS: Over a 7.5-year period, three treatment regimens were sequentially utilized: (1) RTOG 83-19, (2) a Johns Hopkins Oncology Center Institutional Pilot Program, and (3) RTOG 88-23. Each treatment program began with an induction phase of external-beam hepatic irradiation (2100 cGy/7 fractions), with concurrent doses of intravenous chemotherapy intended to be radiosensitizing. After induction, patients received cycles of one of the following: (1) intravenous doxorubicin and 5-fluorouracil (5-FU) with or without 131I-polyclonal antiferritin (RTOG 83-19); (2) intrahepatic artery cisplatin (Hopkins Institutional Pilot); or (3) intrahepatic artery cisplatin with or without 131I-polyclonal antiferritin (RTOG 88-23). Analysis of survival results was performed with multivariate and Cox regression methods. RESULTS: The addition of intravenous 131I-polyclonal antiferritin to post-induction cycles of either intravenous doxorubicin and 5-FU or intrahepatic artery cisplatin did not enhance survival. Intrahepatic artery cisplatin treatment yielded median survival duration of 9.1 months and survival at 12 and 24 months of 37% and 9%, respectively. These results were significantly superior to those resulting from use of intravenous doxorubicin and 5-FU (P = 0.0001; median survival duration 3.6 months; 12- and 24-month survival results 17% and 4%, respectively). A significant survival difference for the cisplatin regimen remained even when patients were stratified by previously identified prognostic factors and the results were appropriately adjusted. CONCLUSION: Patients with unresectable alpha-fetoprotein-positive hepatocellular carcinoma experienced improved survival and decreased toxicity when managed with post-induction cycles of intra-arterial cisplatin as compared with intravenous doxorubicin and 5-FU. Intravenous 131I-polyclonal antiferritin did not improve survival when added to either post-induction regimen but dramatically increased hematologic toxicities.

Role of mitomycin in combination with fluorouracil and radiotherapy, and of salvage chemoradiation in the definitive nonsurgical treatment of epidermoid carcinoma of the anal canal: results of a phase III randomized intergroup study.

PURPOSE: Definitive chemoradiation (CR) has replaced radical surgery as the preferred treatment of epidermoid carcinoma of the anal canal. To determine the importance of mitomycin (MMC) in the standard CR regimen and to assess the role of salvage CR in patients who have residual tumor following CR, a phase III randomized trial was undertaken by the Radiation Therapy Oncology Group (RTOG)/Eastern Cooperative Oncology Group (ECOG). PATIENTS AND METHODS: Between August 1988 and December 1991, 310 patients were randomized to receive either radiotherapy (RT) and fluorouracil (5-FU) or radiotherapy, 5-FU, and MMC. Of 291 assessable patients, 145 received 45 to 50.4 Gy of pelvic RT plus 5-FU at 1,000 mg/m2/d for 4 days, and 146 received RT, 5-FU, and MMC (10 mg/m2 per dose for two doses). Patients with residual tumor on posttreatment biopsy were treated with a salvage regimen that consisted of additional pelvic RT (9 Gy), 5-FU, and cisplatin (100 mg/m2). RESULTS: Posttreatment biopsies were positive in 15% of patients in the 5-FU arm versus 7.7% in the MMC arm (P = .135). At 4 years, colostomy rates were lower (9% v 22%; P = .002), colostomy-free survival higher (71% v 59%; P = .014), and disease-free survival higher (73% v 51%; P = .0003) in the MMC arm. A significant difference in overall survival has not been observed at 4 years. Toxicity was greater in the MMC arm (23% v 7% grade 4 and 5 toxicity; P < or = .001). Of 24 assessable patients who underwent salvage CR, 12 (50%) were rendered disease-free. CONCLUSION: Despite greater toxicity, the use of MMC in a definitive CR regimen for anal cancer is justified, particularly in patients with large primary tumors. Salvage CR should be attempted in patients with residual disease following definitive CR before resorting to radical surgery.

Dose escalation in chemoradiation for anal cancer: preliminary results of RTOG 92-08.

PURPOSE: Radiation Therapy Oncology Group experience with chemoradiation for anal cancer has shown a local failure rate of 20% to 30% with radiotherapy doses of 45 to 50 cGy. This study was undertaken to assess the effect of higher radiotherapy doses on toxicity, local control, and survival in this disease. MATERIALS AND METHODS: Forty-seven patients with anal cancers measuring > or = 2 cm were treated with a concurrent combination of two cycles of 5-fluorouracil infusion (1000 mg/m2 over 24 hrs for 4 days) and mitomycin C (10 mg/m2 bolus) plus 59.6 Gy of pelvic and perineal radiotherapy administered over 8.5 weeks, including a 2-week rest period. Patients were followed for toxicity, disease status, and colostomy-free survival. Twenty-three (49%) patients had advanced (T3-4) primary tumors; 42 (92%) patients had NO disease, and 36 (77%) patients had squamous histology. For perspective, a comparative analysis was made with 147 patients treated on the previous RTOG protocol for anal cancers (RTOG 87-04) with identical chemotherapy but radiotherapy doses of 40 to 50.4 Gy. RESULTS: Transient hematologic and skin toxicity predominated during treatment or in early follow-up. One patient developed septicemia and died of multiple gastrointestinal toxicities. Twelve (26%) patients had greater than grade 3 complications and, of these, 9 (20%) had hematologic side effects alone. A comparative analysis with 147 patients treated on RTOG protocol 87-04 showed no significant differences in pretreatment characteristics of disease extent, performance status, or histology. A mandatory 2-week split in the current chemoradiation protocol contrasted with 12% of patients having a 2-week or greater treatment break in RTOG 87-04. Patients treated on the current protocol (RTOG 92-08) had a markedly lower incidence of > or = grade 3 dermal toxicity (34% vs. 55%) but a higher colostomy rate at 1 year (23% vs. 6%) and at 2 years (30% vs. 7%) compared with RTOG 87-04. CONCLUSIONS: Numerical increases in radiotherapy dose over those used in conventional chemotherapy regimens for anal cancers do not appear to increase local control when given in split-course fashion. For higher radiotherapy doses (> 50 Gy) to increase local control, radiation may have to be given in continuous fashion, which almost certainly means that our threshold of acceptable acute toxicity, particularly dermal toxicity, may have to be raised.

Final results of a phase II chemoradiation protocol for locally advanced cervical cancer: RTOG 85-15.

BACKGROUND: The lack of improved cure rates for advanced cervical cancer after three decades of megavoltage radiotherapy (RT) has prompted continued efforts in improved treatment delivery. Concurrent chemoradiation (CR) is one of the several avenues being explored to improve these results. METHODS: Sixty women with advanced cervical cancer (30 patients with unfavorable Stage IIB and 30 patients with Stages III and IVA) were treated with CR comprising of a combination of external and intracavitary RT delivering between 7000 to 7500 cGy total to point A and 5890 to 6015 cGy to point B along with one cycle of 5-FU and mitomycin C and a second cycle of 5-FU and cis-platinum. RESULTS: Grade 3 and 4 RT-related toxicities were 15 and 3%, respectively. Chemotherapy-related Grade 3 and 4 toxicities were 9 and 2%, respectively. The 5-year survival for unfavorable Stage IIB patients was 48%; for Stages III and IVA it was 39%. CONCLUSIONS: The toxicity of this particular CR regimen was acceptable and suggests that further qualitative and quantitative intensification of chemoradiation may be attempted. Retrospective comparisons with PCS studies and previous RTOG studies 79-20 and 80-05 suggest that this particular chemoradiation regimen may offer a modest survival advantage over RT alone for Stages III and IVA disease. A CR regimen with higher doses of radiotherapy and a greater number of active chemotherapeutic agents may yet result in acceptable toxicity and further improve cure rates in advanced and poor prognostic featured cervical cancer.

Ten-year results of chemoradiation for anal cancer: focus on late morbidity.

PURPOSE: To evaluate (a) long-term survival and (b) the incidence and nature of long-term morbidity/ mortality related to chemoradiation using the anal cancer experience. METHODS AND MATERIALS: From January 1979 to April 1987,34 consecutive patients with Stage I (5 patients), II (15 patients), and II (14 patients) cancers of the anal canal were treated definitively with a chemoradiation regimen combining 41.4 Gy pelvic radiotherapy with two concurrent cycles of 5-fluorouracil and mitomycin C. Cumulative actuarial survival was calculated at 10 years and long-term morbidity was categorized per RTOG/EORTC late toxicity criteria. Specific criteria to grade anal toxicity were devised. RESULTS: Cumulative survival for all 34 patients was 92% at 5 years and 85% at 10 years. The most frequent late toxicity was chronic diarrhea in 17 (50%) patients. Five patients (15%) had Grade 3 or 4 late toxicities. Sexual dysfunction was present in 2 of 26 evaluable patients (7%). CONCLUSIONS: Excellent long-term survival and colostomy-free survival is possible for anal cancer patients treated definitively by chemoradiation. Late effects do not appear to be frequent or intense enough to deter the use of chemoradiation in anal cancer. The biologically expected increase in long-term toxicity when combining radiotherapy and chemotherapy is not substantiated by the results of this study.

Long-term palliation of pulmonary artery sarcoma by radical excision and adjuvant therapy.

The case of an extensive pulmonary artery sarcoma managed by radical excision and homograft reconstruction followed by aggressive chemotherapy and irradiation with prolonged survival is presented. Pulmonary artery sarcomas are reviewed with emphasis on the diagnosis and management of these usually fatal tumors.

Improved food intake and reduced nausea and vomiting in patients given a restricted diet while receiving cisplatin chemotherapy.

Administration of cisplatin alone or in combination with other cytotoxic agents commonly produces intractable nausea and vomiting, which is currently controlled through high-dose antiemetic drugs. However, patients often refuse continued therapy because of suboptimal control of nausea and vomiting and substantial decline in nutritional status. In this pilot study, 19 patients receiving cisplatin were evaluated for nausea and vomiting, amount of food intake, and subjective assessment of well-being. The study group received a colorless, odorless, predetermined meal three times daily; the meal included cottage cheese, apple sauce, vanilla ice cream, and other selected foods. Control-group patients selected their own meal. Study-group patients exhibited higher overall food intake, decreased nausea and vomiting, and a higher scored estimation of well-being. The findings of this preliminary study indicate that the study diet helps provide nutrition care to cancer patients receiving cisplatin chemotherapy and helps create an atmosphere where the patient believes he or she has some control in the treatment outcome.

Angiosarcoma in postsurgical lymphedema. An unusual occurrence in a man.

A 63-year-old man underwent partial left axillary node dissection for metastatic melanoma of unknown primary. Lymphedema of his left upper extremity developed after surgery. Eight years later, extensive cutaneous angiosarcoma developed in the edematous limb. The occurrence of cutaneous angiosarcoma in postsurgical lymphedema is extremely rare in men; to our knowledge, our case is the fifth such case thus far reported.

Evaluation of bromodeoxyuridine in glioblastoma multiforme: a Northern California Cancer Center Phase II study.

In a study activated in 1983 and closed in 1987, the Brain Tumor Research Center of the University of California and the Northern California Cancer Center evaluated the effect of bromodeoxyuridine in the treatment of glioblastoma multiforme. A total of 160 patients were evaluable of 173 entered. Patients were to receive a bromodeoxyuridine infusion of 0.8 g/m2 daily over 24 hours for 4 days of each of 6 weeks of radiotherapy directed to the tumor plus a margin delivering a total of 60 Gy. Eligibility requirements included Karnofsky performance status greater than or equal to 70, biopsy or resection and central pathology review by one of the authors. Following radiotherapy patients were to receive chemotherapy with procarbazine, CCNU, and vincristine for 1 year. Median survival was 55.7 weeks and time to failure, 34.5 weeks for the evaluable group of 160 patients. In a univariate analysis the variables that influence survival and time to failure were: age, Karnofsky performance status, bromodeoxyuridine dose and the delivery of at least one procarbazine, CCNU, and vincristine cycle following radiotherapy. In multivariate analysis, age, Karnofsky performance status, and bromodeoxyuridine dose remain significant for time to failure; age and Karnofsky performance status remain significant for survival.

Preliminary results of concurrent radiotherapy and chemotherapy in advanced cervical carcinoma: a phase I-II prospective intergroup NCOG-RTOG Study.

Thirty-eight patients with advanced carcinoma of the cervix were prospectively treated with a concurrent combination of radiotherapy (RT) and chemotherapy (CT) using the drugs 5-fluorouracil (5FU), mitomycin C and cis-platinum as part of a Northern California Oncology Group (NCOG) and Radiation Therapy Oncology Group (RTOG) intergroup study. RT consisted of 36.00 Gy to the pelvis in 4 weeks followed by a 9.00-Gy parametrial boost. This was followed by two intracavitary applications for a total of 4000 mg hr of radium equivalent when possible. 5FU (1000 mg/m2/24 hr for 96 hr by iv infusion) and mitomycin C (10 mg/m2/iv bolus) were given during the second week of external RT. 5FU (dose as above) and cis-platinum (75 mg/m2/iv over 6 hr) were given during the first intracavitary application. Of 36 patients evaluable for toxicity, 11% had grade 3 nonhematological toxicity and 11% had reversible grade 4 hematological toxicity. There were no toxic deaths. A complete response rate of 62.5% was obtained overall (median survival not reached). This study suggests that this particular combination of RT and CT in advanced cervical carcinoma is effective and well tolerated.

Radiotherapy alone and chemoradiation for nonmetastatic esophageal carcinoma. A critical review of chemoradiation.

Sixty-five patients with nonmetastatic (Stages I, II, and III) esophageal cancer (EC) were treated with radiotherapy (RT) alone (56.00 to 61.00 Gy in 6 to 7 weeks) or synchronous combinations of radiotherapy and chemotherapy (RT-CT). RT-CT consisted of 41.40 to 50.40 Gy in 4.5 to 8 weeks with continuous infusion 5-fluorouracil 5-FU (1000 mg/m2/d for 4 days in weeks 1, 4, and 8), mitomycin C (10 mg/m2 intravenously [IV] in weeks 1 and 8), cisplatin (75 mg/m2 IV in week 4). Maintenance CT consisted of methotrexate (200 mg/m2 IV), leucovorin (10 mg/m2 orally every 6 hours for 5 doses), and 5-FU (600 mg/m2 IV) in weeks 10, 12, and 14. Thirty-five patients treated by RT alone (Group A) were comparable in terms of age, sex, AJC staging, histologic condition, and location of primary with 30 patients treated by RT-CT (Group B). In Group A (range, 2- to 144+ months), two patients (42 and 144 months) are alive and well. In Group B (range, 2- to 59+ months), 12 patients (7 to 59 months) are alive and well. Median survival in Group A is 8 months, compared with 15 months for patients achieving a complete response (CR) in Group B. Patients in Group B achieved a 77% CR rate by endoscopy-biopsy, whereas 30% of the patients in Group A achieved a CR (P = 0.0001). The recurrence rates at the primary site/regional nodes were 77% and 27% in Groups A and B, respectively (P = 0.0001). The incidences of distant metastases were 29% and 20%, respectively (P = 0.423). In Group A, the 1-year and 2-year cumulative survival rates were 27% and 13%, respectively. In Group B, the cumulative survival rates were 53% at 1 year and 29% at 2 years (P = 0.023). Aside from reversible myelotoxicity, the incidences of pulmonary fibrosis, esophagitis, and fistulae formation were less frequent in the combined technique treatment group. A compilation of reported chemoradiation protocols for EC indicates consistently improved 1-year and 2-year survival rates, compared with surgical and RT series. The key to further improvement in the treatment of EC appears to lie in increasing the biologic response (RT fractionation and endocavitary RT) and optimal use of multiple effective CT agents with nonadditive toxicities.

This article reports the previously undescribed occurrence of Hodgkin's disease in a child with neuronal ceroid-lipofuscinosis.

Clinical potential of synchronous radiotherapy and chemotherapy for advanced squamous cell carcinoma.

The equivocal results of past treatment regimens in which concurrent radiotherapy and chemotherapy were used may have resulted from a lack of site-specific active drugs that were also true radiation sensitizers. This report demonstrates an experience with 3 chemotherapeutic agents, 5-fluorouracil, cisplatin, and mitomycin, given simultaneously with radiation for locally advanced squamous cell carcinomas of such diverse sites as the anal canal, cervix, and esophagus. Early results show that the toxicity of these combination regimens is generally acceptable and indicate that such synchronous combination treatments may be superior in local control and survival to radiotherapy alone.

Preliminary results of concomitant radiotherapy and chemotherapy in advanced cervical carcinoma.

Ten patients with advanced and previously untreated squamous cell carcinoma of the cervix were treated with a synchronous course of radiotherapy (RT) and chemotherapy (CT). RT consisted of 3600 to 4500 cGy external pelvic treatments on a 6-MeV linear accelerator followed by two intracavitary applications administering a total of 4000 mg hr of radium equivalent cesium. CT consisted of a course of mitomycin C (10 mg/m2 iv bolus) and 5-fluorouracil (5FU; 1000 mg/m2/24 hr for 96 hr) during the second week of external RT and another course of cis-platinum (CDDP; 75 mg/m2, 1-6 hr infusion) and 5FU (1000 mg/m2/24 hr for 96 hr) during the first intracavitary cesium application. Toxicity was acceptable and complete clinical response was obtained in all patients at the end of the regimen. Nine patients are alive (eight without disease) 6 to 37 months following initiation of treatment (median 20 months). One patient has developed lumbar spine bone metastases and another died of local and pulmonary disease at 28 months. This combination of 5FU/mitomycin C/CDDP and RT appears to be a practical, well-tolerated, and highly effective regimen for advanced cervical carcinoma.

Amyloid tumor of the spleen.

An unusual case of amyloid tumor of the spleen that developed in a patient with malignant lymphoma is reported. A splenectomy performed for a persistent splenic lesion after an otherwise complete response to chemotherapy revealed the amyloid tumor. To our knowledge, amyloid tumor has not been previously described in the spleen.
