Background: The 2012 ASCO provisional clinical opinion addressed the integration of palliative care into standard oncology practice at the time a person is diagnosed with metastatic or advanced cancer. The inclusion of Palliative Care among the National Quality Forum (NQF) framework represented a major advance in palliative care. NQF metrics include chemotherapy administered in the last 14 days of life, hospice less than 3 days before death, ICU or hospital admission, more than one Emergency Room visit in the last 30 days, and death in hospital. Although the use of hospice and other palliative care services has increased, many are enrolled in hospice less than 3 weeks before death. By improving quality of life, cost, and survival in patients with metastatic cancer, palliative care has increasing relevance for the care of patients with cancer. Methods: Retrospective chart review study of lung cancer patients diagnosed at VA from 2010-2013. Inclusion criteria: > 18 years of age with new diagnosis of metastatic lung cancer. Exclusion criteria: < 18 years of age, Stage I-III lung cancer. Results: Total of 125 patients were diagnosed with Stage IV lung cancer. The mean time from diagnosis to death was only 185 days (6.1 months). The VA NYHHS patients were more likely to visit the ED, be admitted to the hospital and ICU in the last 30 days of life, and subsequently die in the hospital. Conclusions: Several confounders were identified, including climate related closure of facilities (2012 Sandy storm), lack of social support, low ICU admission criteria, burial benefits for patients dying in a VA, and delay in transition to Hospice. Currently 392 patients with stage IV solid tumors diagnosed 2010-2014 are being studied. (table present)

OBJECTIVE: We report a single-institution Phase I or II trial of surgical debulking, intraperitoneal chemotherapy, and immunotherapy followed by whole abdominal radiotherapy in patients with malignant peritoneal mesothelioma. METHODS: Between 1997 and 2000, 27 patients with malignant peritoneal mesothelioma were enrolled: 23 with epithelial subtype and 4 with sarcomatoid or mixed subtype. The treatment regimen consisted of surgical debulking followed by 4 intraperitoneal courses of cisplatin alternating with 4 courses of doxorubicin, 4 doses of intraperitoneal gamma interferon, a second laparotomy with resection of residual disease plus intraoperative intraperitoneal mitomycin and cisplatin heated to 41 degrees C, and finally whole abdominal radiotherapy. RESULTS: The median overall survival was 70 months with a 3-year survival of 67% (95% confidence interval, 46%-81%). Fourteen patients have died of their disease with a median time to death of 17 months (range, 0.4-71 months) after consenting to treatment. Seven patients are alive without evidence of disease with a median follow-up of 90 months (range, 71-110 months), and 6 are alive with disease with a median follow-up of 86 months (range, 70-106 months). The regimen was well tolerated. There were no patients with Grade III or IV hematological toxicities, 2 patients with Grade III ototoxicity, and 3 patients with Grade III gastrointestinal toxicity. CONCLUSION: Based on the results of this study, intensive multimodality therapy appears feasible and effective in this group of patients

BACKGROUND: The objective of this study was to assess the efficacy and toxicity of the imidazotetrazine derivative temozolomide for patients with unresectable or metastatic soft tissue sarcoma. METHODS: Twenty-five of 26 patients were eligible and assessable for toxicity and response. Temozolomide was administered twice daily on a 12-hour schedule for 5 days as an oral bolus dose of 200 mg/m(2) followed by 9 doses of 90 mg/m(2) every 4 weeks. RESULTS: There were 2 partial responses, 2 mixed responses, and 3 patients with stable disease that lasted > 6 months, for an overall objective response rate of 8%. At a median follow-up of 13.2 months, the median progression-free survival and the median overall survival were 2.0 months (95% confidence interval [95% CI], 1.7-2.3) and 13.2 months (95% CI, 4.7-31.1), respectively. All responding patients had leiomyosarcoma of uterine or nonuterine origin; and, in a subset analysis of these patients, the objective response rate was 18% (2 of 11 patients), with disease stabilization occurring in 3 of 11 patients (27%). For this subgroup, at a median follow-up of 24.4 months, the median progression-free survival and the median overall survival were 3.9 months (95% CI, 1.9-21.9) and 30.8 months (lower-bound 95% CI, 7.8), respectively. There were no treatment-related deaths or National Cancer Institute Grade 4 toxicities. Grade 3 toxicities included nausea, anemia, fatigue, elevated alkaline phosphatase levels and nonneutropenic fever (1 patient each). CONCLUSIONS: Temozolomide at the dose schedule employed in the current study was tolerated well and had modest activity against previously treated unresectable or metastatic leiomyosarcoma of both uterine and nonuterine origin

The efficacy of current standard therapies for the treatment of sarcoma remains limited. With the aim of identifying target antigens relevant to the development of vaccine-based immunotherapy of sarcoma, we have addressed the relevance of tumor-specific antigens encoded by genes belonging to the SSX family as vaccine targets in sarcoma tumors. Expression of SSX-1 to -5 was analyzed in a collection of sarcoma tumors of diverse histological subtypes and in sarcoma cell lines. We found expression of at least one SSX-encoded antigen in 42% of sarcoma tumors, including 5 of 7 different histological subtypes, and in 50% of sarcoma cell lines. SSX-1 was the most frequently expressed family member, followed by SSX-4, -2 and -5. Expression of SSX-3 was detected in only one sample. Importantly, most SSX positive samples co-expressed more than one family member. In addition, assessment of CD8+ T cell recognition of HLA-A2+ SSX-2+ sarcoma cells showed that the latter were efficiently recognized and lysed by SSX-2-specific CTLs. The results of this study indicate that SSX antigens are relevant targets for the development of vaccine-based immunotherapy of sarcoma and encourage the start of vaccination trials using SSX-derived immunogens in sarcoma patients

BACKGROUND: The current study was conducted to assess the activity and toxicity of high-dose ifosfamide and mesna with recombinant human granulocyte-colony-stimulating factor (rhG-CSF), given in an outpatient setting, in the treatment of patients with unresectable malignant mesothelioma. METHODS: Between September 1994 and September 1996, 41 patients with histologically verified, unresectable malignant mesothelioma were registered, 38 of whom were analyzable (2 were ineligible and 1 was nonanalyzable). Patients received intravenous ifosfamide at a dose of 2.8 g/m2 over 3 hours (total dose of 14 g/m2), plus mesna at a dose of 0.56 g/m2 prior to and at 4 hours and 8 hours after ifosfamide infusion daily for 5 days every 21 days. rhG-CSF at a dose of 5 microg/kg/day was administered subcutaneously on days 6-15. RESULTS: Response assessment could be determined adequately in 21 patients. Two patients obtained responses; 1 was a confirmed partial response (3%; 95% confidence interval [95% CI], 0-14%) and 1 was an unconfirmed response (3%; 95% CI, 5-14%). Eleven patients had stable disease (29%), 7 patients developed disease progression (18%), 1 patient had an early death (3%), and 17 patients had inadequate assessment (45%). At the time of last follow-up, 36 of the 38 eligible patients had developed disease progression, with a median progression-free survival of 5 months (95% CI, 3-7 months) and 34 patients had died with a median survival of 7 months (95% CI, 6-9 months). Twenty-four patients (63%) and 7 patients (18%), respectively, had Grade (according to Southwestern Oncology Group Toxicity Criteria) 4 hematologic toxicities and Grade 4 nonhematological toxicities. There was one treatment-related death, the result of infection, pulmonary edema, and renal failure. CONCLUSIONS: This regimen demonstrated a low overall objective response rate with substantial toxicity, and in the opinion of the authors does not warrant further investigation in the treatment of patients with unresectable malignant mesothelioma

As both fludarabine and rituximab are active against indolent lymphoproliferative disorders, we have studied the combination of fludarabine and rituximab in patients with low-grade lymphoma and chronic lymphocytic leukemia (CLL) in phase I/II fashion. Of 33 patients enrolled, 21(63.6%) had low-grade lymphoma and 12 (36.4%) had CLL. They received fludarabine 30 mg/m2 on days 1-4 and rituximab 125, 250 or 375 mg/m2 on day 5 at intervals of 28 days to a maximum of 8 cycles. Three patients were removed from the study because of rituximab-associated anaphylaxis and four because of prolonged hematopoietic toxicity. Toxicity and responsiveness did not differ at the different dose levels of rituximab. For 29 evaluable patients, responses were seen in 82.8% and complete responses in 34.5%. Of 7 responding patients not referred for stem cell transplantation, 6 remain in complete remission at a median follow-up of 16 months (range 4-30 months). Of 13 previously untreated patients, all responded and 46.2% had a complete response. Of 16 previously treated patients, 68.5% responded and 25% had a complete response. The combination of fludarabine and rituximab has major activity and acceptable toxicity in patients with low-grade lymphoma and CLL

BACKGROUND: The similarity between the mechanism of action between docetaxel and estramustine generated the hypothesis of synergistic antimicrotubule effects and cytotoxicity when the two agents are combined. In addition, it has been demonstrated that estramustine binds P-glycoprotein in vitro and, thus, may prevent the efflux of taxanes in tumors that over-express P-glycoprotein. To further evaluate the combinations clinical efficacy and safety, a trial was performed in heavily pretreated patients with metastatic breast carcinoma (MBC). METHODS: Thirty-six patients with MBC were treated with estramustine 900 mg/m(2) per day divided into 3 doses given on Days 1-3 and docetaxel 70 mg/m(2) given by intravenous administration over 1 hour on Day 3 after the first dose of estramustine, every 21 days. Patients may have received any number of prior chemotherapy regimens for MBC. RESULTS: Nine partial responses were observed in 31 assessable patients, for an objective response rate of 29% (95% confidence interval, 14-48%). The median progression free survival was 4 months (range, 1-41 months), and the median overall survival was 17 months (range, 2-45 months). Severe toxicities (Grade 3 or 4) were neutropenia, hypophosphatemia, and thrombosis. Seventy-five percent of patients experienced either an improvement or no change in quality of life. CONCLUSIONS: The combination of docetaxel and estramustine produced responses in heavily pretreated women with MBC while maintaining quality of life

The cancer-testis antigen NY-ESO-1 is one of the most promising candidates for generic vaccination of cancer patients. Here we analyzed the CD8(+) T cell response to a NY-ESO-1 peptide vaccine composed of the two previously defined peptides 157-165 and 157-167, administered with GM-CSF as a systemic adjuvant. The NY-ESO-1 peptide vaccine elicited a CD8(+) T cell response directed against multiple distinct epitopes in the 157-167 region, as revealed by using A2/peptide multimers incorporating overlapping A2 binding peptides in this region. However, only a minor fraction of the elicited CD8(+) T cells, namely those recognizing the peptide 157-165 with sufficiently high functional avidity, recognized the naturally processed target on NY-ESO-1(+) tumor cells. In contrast, the majority of peptide 157-165-specific CD8(+) T cells exhibited lower functional avidity and no tumor reactivity. In addition, vaccine-elicited CD8(+) T cells specific for other overlapping epitopes in the 157-167 region failed to significantly recognize NY-ESO-1-expressing tumor targets. Thus, because of the complexity of the CD8(+) T cell repertoire that can be elicited by vaccination with synthetic peptides, a precise definition of the targeted epitope, and hence, of the corresponding peptide to be used as immunogen, is required to ensure a precise tumor targeting

OBJECTIVE: The prognosis for patients with primary cardiac sarcoma is poor. Median survival is less than 10 months, especially when complete surgical excision is not feasible. Removal of all cardiopulmonary structures involved by tumor followed by orthotopic allotransplantation has been proposed to improve long-term survival. METHODS: From 1996 through 1999, we performed combined heart and lung resection followed by en bloc heart and bilateral lung transplantation in 4 patients (2 men and 2 women): 2 with inoperable pulmonary arterial sarcoma and 2 with left atrial sarcoma extending into the pulmonary vein. RESULTS: Median age at diagnosis was 39 years (range 37-45 years). All 4 patients were given chemotherapy before transplantation: doxorubicin and ifosfamide in 2 cases, and doxorubicin, ifosfamide, mesna, and dacarbazine in 2 cases. There were no operative deaths. Median survival after transplantation was 31 months (range 5-49 months). All patients had tumor recurrence: local recurrence in the chest (n = 1) and distant metastases in the brain (n = 2) and abdomen (n = 1). One patient remains alive 49 months after disease progression with cerebral metastasis as the only site of recurrence treated with whole-brain irradiation, resection, and stereotactic radiosurgery. CONCLUSIONS: Combined heart and lung transplantation is a technically feasible treatment for highly selected patients with localized advanced primary cardiac sarcomas. The high incidence of metastatic disease, however, limits its utility
