Between March 1974 and December 1983, 83 patients with diffuse histiocytic lymphoma (DHL) were treated with COMLA (cyclophosphamide 1.5 g/m2 day 1; Oncovin (Lilly, Indianapolis) 1.4 mg/m2 days 1, 8, and 15; and cytosine arabinoside 300 mg/m2 and methotrexate 120 mg/m2 days 22, 29, 36, 43, 50, 57, 64, and 71; and leucovorin 25 mg/m2 every six hours X 4, beginning 24 hours after methotrexate). For the purpose of analysis, patients were divided into two groups. Group 1 (n = 54) included patients age 65 or under who had received no prior curative radiotherapy or chemotherapy. Group 2 (n = 29) included all patients over age 65 and patients who had received prior curative radiation therapy or prior minimal chemotherapy. The median time of follow-up for all patients was 28 months. Group 1 included 11 stage II, ten stage III, and 33 stage IV patients. Of 48 evaluable patients in this group, 21 (44%) achieved a complete remission (CR), eight (17%) achieved a partial remission (PR), and 19 (40%) showed no response (NR). Median survival of CR patients was 114+ months, PR patients, 42 months, and NR patients, 13 months. Six CR patients relapsed. The median disease-free survival of CR patients was 108+ months. Group 2 included nine stage II, seven stage III, and 13 stage IV patients. Of 24 patients evaluable for response, eight (33%) achieved a CR, six (25%) achieved a PR, and ten (42%) showed no response. The median survival of CR patients was 114+ months, that of PR patients was 17 months, and that of NR patients, 9 months. Two CR patients relapsed. The median disease-free survival of CR patients had not been reached at 102 months. The regimen was well tolerated in most patients and toxicity was acceptable. We conclude that COMLA is a well tolerated outpatient chemotherapy regimen capable of inducing durable CRs in some patients with DHL. Results achieved with COMLA, however, are inferior to those of more aggressive treatment programs; thus, the use of COMLA as first-line therapy in DHL should be limited to those patients unable to tolerate a more aggressive treatment program.

Abstract OBJECTIVES The association of unstable heart disease and resectable lung cancer is rare. The impacts of staged management, cardiac surgery with cardiopulmonary bypass (CPB) versus angioplasty, on long-term survival and cancer recurrence remain debated. We report our experience using staged management. METHODS From 1997 to 2016, 107 patients were treated at the Quebec Heart and Lung Institute: 72 underwent cardiac surgery with CPB (group 1), 35 were treated with angioplasty (group 2), followed by oncological pulmonary resection. RESULTS Two postoperative deaths (3%) and 1 ischaemic heart complication (1%) were reported in group 1. One death (3%) was reported in group 2. Two-year overall survival was 82% (59/72) in group 1 and 80% (28/35) in group 2; 5-year overall survival was 62% (33/53) in group 1 and 63% (19/30) in group 2. Two-year disease-free survival in group 1 was 79% (57/72) and 77% (27/35) in group 2; 5-year disease-free survival was 58% (31/53) in group 1 and 60% (18/30) in group 2. The independent risk factors for death after thoracic surgery were transfusions (P = 0.004) and grade ≥3 complications (P = 0.034). Independent risk factors for recurrence included the cancer stage (P < 0.001) and, paradoxically, a shorter delay between cardiac and lung procedures (P = 0.031). CONCLUSIONS When a staged management remains feasible after cardiac procedure, oncological outcomes of patients with cardiopathy and lung cancer are satisfactory. CPB does not seem to be deleterious. The delay between procedures should intuitively be as small as possible but not at the expense of good recovery after the cardiac procedure.

Twenty-eight patients with previously untreated diffuse histiocytic lymphoma (DHL) were identified to be in pathologic stage (PS) I (11), IE (3), II (8), or IIE (6) by exploratory laparotomy and splenectomy. Six patients were treated with total nodal radiotherapy; 14 with an extended mantle; 5 with an inverted Y or whole abdomen; and 3 with an involved field. Twenty-six patients achieved a complete remission (93%) and 2 patients had persistent local disease. The median survival and disease-free survival and for the complete response group are 56 and 51.5 mo, respectively. Ten of the 11 stage I or IE patients had supradiaphragmatic lymph node disease. Patients with stage I or IE disease (n = 14) demonstrated a median survival of 72.5 mo and a median disease-free survival of 69.5 mo; there was 1 disease-related death. Patients with stage II or IIE disease (n = 14) demonstrated a median survival of 33 mo and median disease-free survival of 29.5 mo; there were 10 relapses or deaths. Patients in stages I, IE, II, or IIE with infradiaphragmatic disease (n = 7) had a median survival of 36 mo, while patients with supradiaphragmatic presentation (n = 21) demonstrated median survival of 68 mo (p = 0.37). The data indicate that patients with diffuse histiocytic lymphoma with stage I supradiaphragmatic lymph node disease are curable using radiotherapy alone, achieving a 93% 11-yr actuarial disease-free survival. Patients with stage II or IIE diseases are not readily curable with radiation therapy alone, achieving a 33% 11-yr actuarial disease-free survival; radiotherapy with adjuvant chemotherapy or chemotherapy alone should be considered for this group.

ABSTRACT Background The approach of locally advanced extra-peritoneal rectal adenocarcinoma implies a treatment with neoadjuvant chemoradiotherapy associated with total mesorectal excision surgery. However, the tumors respond variably to this neoadjuvant therapy, and the mechanisms for response are not completely understood. Objective Evaluate the variables related to the complete tumor response and the outcomes of patients who underwent surgery, comparing those with partial tumor regression and those with total remission of rectal lesion, at the pathological examination. Methods Retrospective analysis of medical records of 212 patients operated between 2000 and 2010, in which 182 (85.9%) obtained partial remission at neoadjuvant therapy (Group 1) and 30 (14.1%), total remission (Group 2). Results No difference was found between the groups in relation to gender, ethnicity, age, tumor distance from the anal verge, occurrence of metastases and synchronous lesions on preoperative staging, dose of radiotherapy and performed surgery. In Group 2, was verified high rate of complete remission when the time to surgery after neoadjuvant therapy was equal or less than 8 weeks (P=0.027), and a tendency of lower levels of pretreatment carcinoembryonic antigen (P=0.067). In pathological analysis, the Group 1 presented in relation to Group 2, more affected lymph nodes (average 1.9 and 0.5 respectively; P=0.003), more angiolymphatic (19.2% and 3.3%; P=0.032) and perineural involvement (15.4% and 0%; P=0.017) and greater number of lymph nodes examined (16.3 and 13.6; P=0.023). In the late follow-up, Group 1 also had lower overall survival than Group 2 (94.1 months and 136.4 months respectively; P=0.02) and disease-free survival (85.5 months and 134.6 months; P=0.004). There was no statistical difference between Group 2 and Group 1 in local recurrence (15% and 3.4%, respectively) and distant metastasis (28% and 13.8%, respectively). Conclusion In this study, the only factor associated with complete remission of rectal adenocarcinoma was the time between neoadjuvant therapy and surgery. This group of patients had less affected lymph nodes, less angiolymphatic and perineural involvement, a longer overall and disease-free survival, but no significant statistical difference was observed in local recurrence and distant metastasis. Although the complete pathologic remission was associated with better prognosis, this not implied in the cure of the disease for all patients.

e14173 Background: Colorectal cancer is the second most common cancer with 2,4 million people diagnosed. The rectal cancer (RC) is 27% of these cases. Neoadjuvant chemoradiotherapy (NCRT) has become standard but brought controversy in the adjuvant treatment. The objective was to assess the impact of adjuvant chemotherapy after NCRT. Methods: Between mar/96 and Oct/2010, 84 patients received NCRT, and 58 patients underwent resection of the rectum. The NCRT consisted of 5-FU 350mg/m2, D1-D5 (50% of cases) or 5-FU 425mg/m2, D1-D3 (43%) with LV 20mg/m2 bolus in the 1st and 5th week of the 25 sessions of radiotherapy in linear accelerator (total 45 - 50 Gy). When performed, Adjuvant chemotherapy (ADJC) consisted of 5-FU 425mg/m2, LV 20mg/m2, both on D1-D5 for 4 cycles. Evaluation of Overall Survival (O.S) and Disease-Free Survival (DFS) performed using Kaplan-Meier curve in SPSS version 13.0 Results: Of the 58 patients who underwent surgery, 90% were stage II, 51% occurred in the lower rectum and 66% were ECOG 1. Pathologic Complete Response (PCR) was obtained in 25.8% (15) of patients (group 1). Of these, 20% (3) received ADJC. Patients without PCR (group 2) received ADJC in 51% of the cases (22). The mean follow-up was 41 months. Both the DFS (HR: 2.594, 95% CI: 1134-5938, p = 0.024) and OS (HR: 2.615, 95% CI: 1005-6807, p = 0.0488) were higher in patients with PCR independent of the use of ADJC. On the other hand, patient treated with ADJC vs without ADJC, independent of presence of PCR, did not alter DFS (p = 0.74) or OS (p = 0.32). In PCR patients, ADJC do not interfere in the outcome (DFS, p = 0.76; SG, p = 0.73). In group 2 (patients without PCR), the subgroup with ADJC, there was a trend towards better SLD (p = 0.06) and OS (p = 0.06). Those who did not receive ADJC in group 2 had worse SLD (p = 0.011) and OS (p = 0.028) compared with group-1. Conclusions: Adjuvant treatment after NCRT did not increase OS or DFS. Patients without PRC had worse results without ADJC, compared to those with PCR. The first, probably, the subgroup of patients who benefited most from the use of ADJC. PCR improves OS and DFS regardless of ADJC, being perhaps the group that does not deserve ADJC.

Aim. To improve the surgical treatment results among patients with synchronous liver metastasis of colorectal cancer. Materials and methods. From 2012 to 2019, the analysis of the results of treatment of 60 patients with colorectal cancer and synchronous metastatic liver disease was carried out. The study sample was divided into 2 groups of patients. The group 1 consisted of 30 patients who got simultaneous resection of liver metastases and primary colorectal cancer. The group 2 consisted of other 30 patients who got stage resections: surgery for the primary tumor at the first stage, and liver surgery for metastases at the second.Results. The median operative time was 340 ± 21.1 minutes in the group 1. In the group 2 it was 255 ± 21.1 minutes and only the liver resection stage was assessed. The median blood loss in patients of the group 1 was 520,0 [200,0;800,1] ml, in the group 2 it was 500,0 [175,0;1300,0] ml. In general, we identified 5 cases of complications. In the postoperative period, 4 patients died. The average follow-up period is 23 months. One-year survival in group 1 was 92.6%, in group 2 – 100%, three-year – 85.2% and 89.6%. One-year disease-free survival in group 1 is 70%, in group 2 – 83.3%, three-year disease-free survival – 43.3% and 36.7%.Overall and disease-free survival rates didn’t differ significantly between the two treatment strategies. We detected significant effect on the disease-free and overall survival of regional lymph nodes metastasis (both p < 0.05).Conclusion. The long-term and immediate results of simultaneous surgery of synchronous liver metastasis of colorectal cancer are comparable to the results of the staged method of treatment. It indicates the safety and effectiveness of simultaneous procedure.

e15569 Background: Neuroendocrine tumors of the uterine cervix are rare, aggressive, and carry a poor prognosis. Most are small cell (SCNEC) and large cell (LCNEC). The limited knowledge of this neoplasm is based on small series due to the rarity of the diagnosis.There is a lack of information about NEC in Latin America. We describe both demographic and clinical characteristic of Mexican patients; and their multidisciplinary management in a reference center. Methods: We studied retrospectively clinical and histopathological variables of 33 women treated at the National Cancer Institute of Mexico from 1991 to 2010 with NEC. Patients were allocated into groups according to staging (Group 1 FIGO stages IB1 and IB2; Group 2 IIA-IVA, and Group 3 IVB). Results: Mean age at diagnosis was 50 y.o.; mean tumour size was 4.9 cm. There were 59.4% SCNEC and 40.6% LCNEC. Stage at diagnosis: IB1 15% (n=5), IB2 3% (n=1), IIA 18.2% (n=6), IIB 27.3% (n=9), IIIA 6% (n=2), IVB 27.3% (n=9). Common sites of metastases were lung and liver. The most common presenting symptom was transvaginal bleeding. In Group 1, 6/7 patients received multimodal management with surgery, chemoradiotherapy and induction or adjuvant chemotherapy. In Group 2, 12/17 patients received three modalities, 3/17 received only 2, due to comorbidty. In Group 3, 8/9 received 2 modalities. Patients with one treatment modality were those with disease progression. Cisplatin was used concurrently with radiotherapy; paclitaxel and carboplatin or etoposide and cisplatin were used for either induction or adjuvant settings. Disease free survival in months was: 50.3 (group 1); 23.1 (group 2), and 3.5 (group 3). Overall survival was: 68.5, 46.3, and 17.2 months, respectively. Main sites of recurrence were pelvis, mediastinum, lung, liver, central nervous system, pancreas, adrenal gland, bone and soft tissue. Conclusions: TheNational Cancer Institute of Mexico offers multidisciplinary treatment emphasizing local control after systemic therapy in both early and locally advanced disease; providing the most favourable disease-free survival and overall survival described. To our knowledge, this is the first report of NEC in the Mexican population, where carcinoma of uterine cervix represents yet an important public health issue.

From January 1970 to March 1981, localized diffuse histiocytic lymphoma (DHL) was identified in 31 patients by exploratory laparotomy and splenectomy (pathologic stage I, 17 patients; pathologic stage II, 14 patients) at the University of Chicago. The median follow-up time was 72 months. All patients were previously untreated and received radiation therapy as their primary treatment modality. Chemotherapy was administered only at the time of relapse. All but two patients achieved a complete remission (CR) with radiation therapy. The actuarial disease-free survival for patients with stage I disease is 94% at 5 years and 72% at 10 years. For stage II disease, the disease-free survival is 56% at 5 years and 31% at 10 years. The difference in the disease-free survival between stage I and II is statistically significant (P = .02). The survival at 10 years is 70% for stage I disease and 46% for stage II disease. Five patients had documented relapses (four had stage II disease). Only two of those who relapsed achieved a second CR with salvage chemotherapy. Our data show an excellent outcome in patients with pathologic stage I disease, indicating that a high percentage of these cases can be cured with radiotherapy alone. Patients with clinical stage II disease might be served better with chemotherapy.

BackgroundThe tumor lysate, particle-loaded, dendritic cell (TLPLDC) vaccine is created ex vivo by loading autologous dendritic cells (DC) with yeast cell wall particles (YCWP) containing autologous tumor lysate, thus delivering tumor antigens to the DC cytoplasm via phagocytosis. TLPLDC then activates a robust T cell response against the unique antigens for each patient. The primary analysis of the prospective, randomized, multi-center, double-blind, placebo-controlled phase IIb trial in patients with resected stage III/IV melanoma showed TLPLDC improved 24-month disease-free survival (DFS) in the per-treatment (PT) analysis (patients completing the 6-month primary vaccine series). Here, we examine the secondary endpoint of 36-month DFS and overall survival (OS).MethodsPatients with resected stage III/IV melanoma were randomized 2:1 to TLPLDC vaccine or placebo (autologous DC loaded with empty YCWP). Treatments were given at 0, 1, 2, 6, 12 and 18 months. The protocol was amended to include patients receiving concurrent checkpoint inhibitors (CPIs) to follow changes in standard of care. The co-primary endpoints were 24-month DFS by intention-to-treat (IT) analysis and per-treatment (PT) analysis, with secondary endpoints including 36-month DFS and OS by ITT and PT analysis, pre-specified analysis by stage, and safety as measured by CTCAE v4.03.ResultsOverall, 103 patients received TLPLDC and 41 placebo. In PT analysis, 65 patients received TLPLDC and 32 placebo. Total adverse events (AEs), grade 3+ AEs, and serious AEs (SAEs) were similar in placebo vs TLPLDC groups, with one related SAE per treatment arm. By ITT analysis, 36-month OS was 76.2% for TLPLDC vs 70.3% for placebo (HR 0.72, p=0.437) and 36-month DFS was 35.6% vs 27.1% (HR 0.95, p=0.841). By PT analysis, 36-month DFS was improved with TLPLDC (57.5% vs 35.0%; HR 0.50, p=0.025, figure 1). This effect was even more dramatic in resected stage IV patients (36-month DFS: 60.9% vs 0%; HR 0.12, p=0.001, figure 2).ConclusionsThis phase IIb trial again demonstrates the safety of the TLPLDC vaccine, and an improved 36-month DFS in patients with resected stage III/IV melanoma who complete the primary vaccine series, particularly in the stage IV subgroup. Next, a phase III trial will evaluate the efficacy of TLPLDC vaccine as adjuvant treatment for resected stage IV melanoma, with patients randomized to receive standard of care PD-1 inhibitors + TLPLDC versus PD-1 inhibitors + placebo.Abstract 300 Figure 136-month disease free survival for patients receiving TLPLDC vs placebo by PT analysisAbstract 300 Figure 236-month disease free survival for subset of stage IV melanoma patients receiving TLPLDC vs placebo by PT analysisTrial RegistrationThis is a phase IIb clinical trial registered under NCT02301611Ethics ApprovalThis study was approved by Western IRB, protocol 20141932.

Twenty-six of 45 adults (58%) with acute nonlymphocytic leukemia who were treated with intensive induction chemotherapy over 5 yr ago entered complete remission. All patients entering remission were placed on weekly maintenance chemotherapy consisting of cytosine arabinoside and 6-thioguanine. The median duration of complete remission was 17 mo and 7 patients (27%) remained in their initial remission for 62 + to 102 + mo. All but one of the patients in complete remission over 5 yr have had treatment discontinued. Only 1 of 7 patients in remission for more than 5 yr has relapsed. Median survival is 26.5 mo, and 8 patients (31%) currently remain alive without evidence of leukemia 63--105 mo from diagnosis. It is possible to achieve long-term disease-free survival with chemotherapy alone in acute nonlymphocytic leukemia.
