    Abstract: As cancer surgery restarts after the first COVID-19 wave, health care providers urgently require data to determine where elective surgery is best performed. This study aimed to determine whether COVID-19–free surgical pathways were associated with lower postoperative pulmonary complication rates compared with hospitals with no defined pathway. PATIENTS AND METHODS This international, multicenter cohort study included patients who underwent elective surgery for 10 solid cancer types without preoperative suspicion of SARS-CoV-2. Participating hospitals included patients from local emergence of SARS-CoV-2 until April 19, 2020. At the time of surgery, hospitals were defined as having a COVID-19–free surgical pathway (complete segregation of the operating theater, critical care, and inpatient ward areas) or no defined pathway (incomplete or no segregation, areas shared with patients with COVID-19). The primary outcome was 30-day postoperative pulmonary complications (pneumonia, acute respiratory distress syndrome, unexpected ventilation). RESULTS Of 9,171 patients from 447 hospitals in 55 countries, 2,481 were operated on in COVID-19–free surgical pathways. Patients who underwent surgery within COVID-19–free surgical pathways were younger with fewer comorbidities than those in hospitals with no defined pathway but with similar proportions of major surgery. After adjustment, pulmonary complication rates were lower with COVID-19–free surgical pathways (2.2% v 4.9%; adjusted odds ratio [aOR], 0.62; 95% CI, 0.44 to 0.86). This was consistent in sensitivity analyses for low-risk patients (American Society of Anesthesiologists grade 1/2), propensity score–matched models, and patients with negative SARS-CoV-2 preoperative tests. The postoperative SARS-CoV-2 infection rate was also lower in COVID-19–free surgical pathways (2.1% v 3.6%; aOR, 0.53; 95% CI, 0.36 to 0.76). CONCLUSION Within available resources, dedicated COVID-19–free surgical pathways should be established to provide safe elective cancer surgery during current and before future SARS-CoV-2 outbreaks.

    Abstract: 572 Background: Peritoneal implantation of mouse renal adenocarcinoma cell-containing (RENCA) Macrobead (MB) represents a cell-system-based approach to the treatment of advanced, mCRC that has been evaluated to date in Phase IIa trials. The data indicate that there are “responders” (R) and “non-responders”(NR) as reflected in overall survival (OS), where “response” is defined as a 〉 20% decrease in either/both CEA or CA19-9 during the first 30 days after MB implantation. We analyzed whether the “response” is due to a post-implant systemic inflammatory response (SIR) or rather a direct inhibitory effect of the MB. Methods: Thirty-four treatment-resistant mCRC patients (pts) were implanted laparoscopically at least once with RENCA MB. Pts were considered R (n=25), or NR (n=9), based on tumor marker responses within the first 30 days. CRP, IL-6, TNF-alpha, and ESR, as measures of SIR, were measured at Day 14 and 30. Results: All 34 pts showed SIR to MB implantation, as indicated by transient rises in CRP, IL-6, TNF-a, and ESR. Baseline CRP values (R, mean 3.24+/-4.39 vs. NR, 2.96+/-3.43; t-test, p=0.86), Day 14 CRP values (R, mean 20.97 +/- 7.21 vs. NR, 14.5+/-8.78; t-test, p=0.04), Day 30 CRP values (R, mean 8.21+/-5.43 vs. NR, 10.76+/-6.92; t-test, p=0.27) and mean changes in IL-6 (baseline p=0.28; Day 14 p=0.36; Day 30 p=0.54), TNF-a (baseline p=0.37; Day 14 p=0.32; Day 30 p=0.29) did not show statistically significant differences between R and NR groups. Conclusions: Data suggest that early tumor marker decreases in R of RENCA MB are likely not due to the induced SIR, but rather a possibly direct anti-tumor-cell effect by factors released by MB. This supports the importance of the MB-induced changes in the MEF-2 pathway in the target colorectal cancer cell/tumor reported previously. Studies of clinical efficacy of MB continue in a Phase IIb clinical trial. Clinical trial information: NCT01053013.

    Abstract: e15046 Background: RMB, a cytostatic, biological system form of anti cancer therapy have been used in Ph I & II clinical trials in mCRC w/ evidence of improved survival benefit & QOL. Evaluation of metastatic tumor response by standard CT RECIST criteria however has been unsatisfactory. We hypothesized that using 18F FDG PET/CT scan to evaluate tumor anatomy & metabolism could provide a more accurate picture of tumor response to RMB Methods: 48 mCRC pts (14, Ph 1; 34, Ph 2a) who failed available treatments were implanted intraperitoneally w/ RMB (8mb/kg). Physicals, biomarkers & lab evaluation were obtained at baseline & days 14-90, with PET CT imaging at baseline & day 90. PET scan was acquired 1 hour after FDG injection of 9.4 mCi. CT was used for attenuation correction. Correlation between 18F FDG PET SUVmax findings & CEA & or CA19-9 responses was assessed. Positive response was defined as ≥20% decrease post implant in CEA, CA19-9 & SUV. Only tumors w/ SUVmax ≥ 2.5 were evaluated. SUV measurements were made by 1 radiologist experienced in PET-CT scanning & SUV determination Results: 123 FDG positive mCRC lesions (39, Ph 1; 84 Ph 2a) were detected in 37 evaluable pts (14 m, 23 f; mean age 58.2; SUVmax 2.5-17.5). Of the 37 pts, 28 (76%) showed stabilization & or decreased FDG uptake (4 w/ frank necrosis) as well as stable/decreased CT tumor measurements. Pts w/ pulmonary lesions showed greater responses than those w/ hepatic lesions. 9 (24%) of 37 pts showed increased SUVs. 23 pts (62%) showed decrease in CEA & or CA 19-9 ≥ 20%. 17 pts (74%; 13 decrease, 4 central & peripheral necrosis) had correlation between decreased SUVs/necrosis & biomarkers decrease Conclusions: We conclude SUVs are useful in monitoring mCRC lesions response to RMB therapy. Changes in SUVs correlate w/ CEA & CA 19-9 changes. Taken together the combined data indicate anti tumor effect in these Ph 1/2a trials & offer preliminary support for our hypothesis that 18FDG can be useful in evaluating cell system therapies. Issues of SUVmax standardization & effects of intra tumor heterogeneity however must be considered. Further studies are merited & ongoing, including a planned Ph 3 trial Clinical trial information: NCT01053013; NCT00283075.

    Abstract: The primary aim of this study was to compare the relative efficacy of oral uracil and tegafur (UFT) plus leucovorin (LV) with the efficacy of weekly intravenous fluorouracil (FU) plus LV in prolonging disease-free survival (DFS) and overall survival (OS) after primary surgery for colon carcinoma. Patients and Methods Between February 1997 and March 1999, 1,608 patients with stage II and III carcinoma of the colon were randomly assigned to receive either oral UFT+LV or intravenous FU+LV. Results Of the total patients, 47% had stage II colon cancer, and 53% had stage III colon cancer. Median follow-up time was 62.3 months. The estimated hazard ratio (HR) for OS of patients who received UFT+LV versus that of patients who received FU+LV was 1.014 (95% CI, 0.825 to 1.246). The estimated HR for DFS was 1.004 (95% CI, 0.847 to 1.190). Cox proportional hazards model analyses with regard to age ( 〈 60 v ≥ 60 years), stage, or number of involved nodes (none v one to three v ≥ four nodes) revealed no interaction with OS or DFS. Toxicity was similar in the two groups. In the UFT+LV arm, 38.2% of patients experienced any grade 3 or 4 toxic event compared with 37.8% of patients in the FU+LV arm. Primary quality-of-life end points did not differ between the two regimens, although convenience of care analysis favored UFT+LV. Conclusion UFT+LV achieved similar DFS and OS when compared with an intravenous, weekly, bolus FU+LV regimen. The two regimens were equitoxic and generally well tolerated.

    Abstract: We investigated the long-term risk of second primary malignancy after chemotherapy for Hodgkin's lymphoma (HL) in a much larger cohort than any yet published, to our knowledge. Patients and Methods We followed 5,798 patients with HL treated with chemotherapy in Britain from 1963 to 2001—of whom 3,432 also received radiotherapy—to assess second primary malignancy risks compared with general population-based expectations. Results Second malignancies occurred in 459 cohort members. Relative risk (RR) of second cancer was raised after chemotherapy alone (RR, 2.0; 95% CI, 1.7 to 2.4) but was much lower than after combined modalities (RR, 3.9; 95% CI, 3.5 to 4.4). After chemotherapy alone, there were significantly raised risks of lung cancer, non-HL, and leukemia, each contributing approximately equal absolute excess risk. After combined modalities, there were raised risks of these and several other cancers. Second cancer risk peaked 5 to 9 years after chemotherapy alone, but it remained raised for 25 years and longer after combined modalities. Risk was raised after each common chemotherapy regimen except, based on limited numbers and follow-up, adriamycin, bleomycin, vinblastine, and dacarbazine. The age and time-course relations of lung cancer differed between chemotherapy alone and combined modalities. Conclusion Although chemotherapy alone leads to raised risk of second malignancy, this risk is lower and affects fewer anatomic sites than that after combined modalities, and it is slight if at all after 15 years follow-up. The mechanism of lung cancer etiology may differ between chemotherapy and radiotherapy.

    Abstract: 258 Background: Effective multimodality treatment for localized pancreatic cancer is elusive. We hypothesized that preoperative fixed-dose rate (FDR) gemcitabine (GEM) combined with short-course radiotherapy (RT) and the angiogenesis inhibitor bevacizumab (BEV) would improve margin negative surgical outcomes and complete pathological response rates. Methods: Multisite phase II trial evaluating all potentially-resectable pancreatic adenocarcinoma without major arterial involvement or portal venous occlusion. Dual primary endpoints included complete pathological response and margin negative resection rates of 10% and 80%. Subjects received FDR GEM on days 1, 15, and 29 combined with BEV (10 mg/kg IV), followed on day 43 by BEV and concurrent 30 Gy RT (3 Gy/fraction) over 10 days. After restaging, subjects underwent laparoscopy and possible resection after day 85. Stopping criteria required continuous monitoring of serious wound complications. Results: 58 subjects enrolled, of which 29 (50%) had suspected venous involvement. 57 completed treatment without dose-limiting toxicity or delays in surgery. Two grade 4 (3.4%) and 17 grade 3 toxicities (28.8%) occurred. Four patients progressed before surgery. 54 subjects underwent laparoscopy; ten had unexpected carcinomatosis, and one was unresectable. 43 subjects were resected (74%; 33 pancreatico-duodenectomy, 8 distal pancreatectomy, 1 total pancreatectomy, 1 Appleby); 19 (44%) required portal vein resection. Margin negative outcome was achieved in 38 (88%, 95% CI: 75%-96%) with one complete pathological response (2.3%; 95% CI: 0.1%- 12%) and seven (6 grade 3; 1 grade 4) wound complications (13%). Median overall survival (OS) was 16.3 months (95% CI: 13.9 -22.1) and 21.3 months (95% CI: 15.0-32.9) after resection. Median progression-free survival (PFS) was 5.7 months (95% CI: 3.9-9.1) and 9.9 months (95% CI: 5.7 to 14.1) after resection, with 7 local and 21 distant recurrences. Conclusions: Combination therapy was well-tolerated and was within statistical design parameters for the primary endpoints despite a significant proportion of borderline tumors.

    Abstract: To assess long-term site-specific risks of second malignancy following non-Hodgkin's lymphoma (NHL) in relation to treatment and demographic factors. Patients and Methods A cohort of 2,456 patients with NHL who were first treated from 1973 to 2000 and were younger than 60 years from centers in the British National Lymphoma Investigation were observed, and occurrences of second malignancy was compared with expectations based on general population cancer rates in England and Wales. Results In total, 123 second malignancies occurred. Relative risks (RRs) were significantly elevated for all malignancies combined (RR = 1.3; 95% CI, 1.1 to 1.6) and for leukemia (RR = 8.8; 95% CI, 5.1 to 14.1) and lung cancer (RR = 1.6; 95% CI, 1.1 to 2.3). RRs of malignancy overall diminished significantly with increasing age at first treatment. Leukemia risk was significantly increased after chemotherapy (RR = 10.5; 95% CI, 5.0 to 19.3) and mixed-modality treatment (RR = 13.0; 95% CI, 5.2 to 26.7). Relative risks of lung (RR = 1.9; 95% CI, 1.1 to 3.1) and colorectal (RR = 2.1; 95% CI, 1.1 to 3.6) cancers were significantly raised following chemotherapy. Conclusion NHL patients are at elevated risk of developing second malignancy, particularly leukemia and lung cancer. The relative risk is greater with patients who are younger at first treatment. Chemotherapy predisposes patients toan increased risk of leukemia, and possibly lung and colorectal cancers. The role of specific drug treatments in the etiology of solid cancers after NHL deserves further investigation.

    Abstract: e14517 Background: RENCA tumor cells encapsulated in two concentric agarose layers which release signals to treat advanced cancers is a novel concept that has been substantiated in in vitro and in vivo models as reported in Cancer Research 71(3), 716-735, 2011.We report results of a phase I/II study in advanced CRC pts. Methods: Previously-treated advanced CRC pts (ECOG PS 0-2) were enrolled with informed consent obtained. Pts had intraperitoneal implantation up to 4 times via laparoscopy with 8 (37/40 pts- established dose) or 16 (3/40 pts) RENCA MB/kg. Serial exams, lab profiles, and imaging were done pre- and 3 months (mo.) post-implant to assess efficacy. Endpoints of safety, tumor marker decrease, response, and overall survival (OS) were evaluated. Results: 40 pts were implanted with RENCA MB (12 pts phase I; 28 pts phase II); 17M: 23F. Mean age 58.3. 14/40 pts had 〉 1 implant (≥2: 14 pts; ≥3: 2 pts; =4: 2 pts). Response to MB is marked by a prominent initial rise in CRP, ESR, and IL-6, indicating a systemic inflammatory response (SIR) (100% of pts) and a parallel decrease in CEA and/or CA 19-9 in approximately 70%. SIR including its accompanying fatigue and anorexia lasts days to 3 wks. Overall, there was a statistically significant difference (p=0.009) in OS between the 70% of pts showing a decrease in tumor markers by at least 20% during the first 30 days post-implant (OS; 9.7 mo., C.I. 6.5-13.5) and those who did not (OS; 4.4 mo., C.I. 1.1-7.6). On PET-CT imaging, a striking feature of response, most often seen in pts with the longest OS, is tumor necrosis. MB were well-tolerated and no Grade ≥3 adverse events were treatment-related. Conclusions: For advanced, treatment-resistant CRC pts, early response to MB implantation characterized by tumor marker decrease in association with SIR correlates with a statistically significant increase in OS. RENCA MB represent a possible new therapeutic option for late-stage CRC. Clinical trial information: NCT01053013.

    Abstract: PURPOSE: Paclitaxel is an active drug for the treatment of breast cancer; however, the appropriate duration of administration is unknown. We assessed and compared the response rate, event-free survival, survival, and toxicity of paclitaxel 250 mg/m 2 delivered every 3 weeks as a 3-hour or 24-hour infusion. PATIENTS AND METHODS: A total of 563 women with stage IV or IIIB breast cancer were randomized into one of two groups: 279 received 3-hour paclitaxel and 284 received 24-hour paclitaxel. Patients were stratified by age, stage of disease, and prior therapy. RESULTS: A significantly higher rate of tumor response occurred in the first four cycles of therapy in patients who received the 24-hour infusion of paclitaxel (51% v 41%, respectively; P = .025). Tumor response over all cycles was also significantly higher in the group that received 24-hour infusion (54% v 44%, respectively; P = .023). There were no significant differences in event-free survival or survival between the two arms of the study (P = .9 and .8, respectively). No treatment by stage or by age interactions were observed. During the first four cycles of therapy, at least one episode of ≥ grade 3 toxicity (excluding nadir hematologic values, alopecia, and weight change) occurred in 45% of patients who received the 3-hour paclitaxel infusion and in 50% of those who received the 24-hour paclitaxel infusion. Febrile neutropenia, ≥ grade 3 infection, and ≥ grade 3 stomatitis were less frequent, and severe neurosensory toxicity was more frequent in those who received the 3-hour paclitaxel infusion. Ten treatment-related deaths occurred in the first four cycles. Age, stage, and prior chemotherapy did not influence the effect of treatment. CONCLUSION: When administered as a continuous 24-hour infusion, high-dose paclitaxel results in a higher tumor response rate than when administered as a 3-hour infusion but does not significantly improve event-free survival or survival. Paclitaxel as a 24-hour infusion results in increased hematologic toxicity and decreased neurosensory toxicity.

    Abstract: Clinical trials frequently include multiple end points that mature at different times. The initial report, typically based on the primary end point, may be published when key planned co-primary or secondary analyses are not yet available. Clinical Trial Updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported. ARST1321 was a phase II study designed to compare the near complete pathologic response rate after preoperative chemoradiation with/without pazopanib in children and adults with intermediate-/high-risk chemotherapy-sensitive body wall/extremity non-Rhabdomyosarcoma Soft Tissue Sarcoma (ClinicalTrials.gov identifier: NCT02180867 ). Enrollment was stopped early following a predetermined interim analysis that found the rate of near complete pathologic response to be significantly greater with the addition of pazopanib. As a planned secondary aim of the study, the outcome data for this cohort were analyzed. Eight-five eligible patients were randomly assigned to receive (regimen A) or not receive (regimen B) pazopanib in combination with ifosfamide and doxorubicin + preoperative radiotherapy followed by primary resection at week 13 and then further chemotherapy at week 25. As of December 31, 2021, at a median survivor follow-up of 3.3 years (range, 0.1-5.8 years), the 3-year event-free survival for all patients in the intent-to-treat analysis was 52.5% (95% CI, 34.8 to 70.2) for regimen A and 50.6% (95% CI, 32 to 69.2) for regimen B ( P = .8677, log-rank test); the 3-year overall survival was 75.7% (95% CI, 59.7 to 91.7) for regimen A and 65.4% (95% CI, 48.1 to 82.7) for regimen B ( P = .1919, log-rank test). Although the rate of near complete pathologic response was significantly greater with the addition of pazopanib, outcomes were not statistically significantly different between the two regimens.
