Abstract: What's new? It is well known that a person's socioeconomic status (SES) affects cancer risk, but few data exist analyzing life‐course SES in low to middle income countries. Here the authors show that low or declining life‐course SES in women was significantly associated with increased smoking and alcohol use. In contrast, high SES was associated with reduced physical activity. The authors recommend that cancer prevention strategies in these countries be tailored to specific SES subgroups to be most efficient.

Abstract: Side effects associated with use of postoperative narcotics for pain control can delay recovery after abdominally based microsurgical breast reconstruction. The authors evaluated a nonnarcotic pain control regimen in conjunction with bilateral transversus abdominis plane blocks on facilitating early hospital discharge. Methods: A retrospective analysis was performed of consecutive patients who underwent breast reconstruction using abdominally based free flaps, with or without being included in a nonnarcotic protocol using intraoperative transversus abdominis plane blockade. During this period, the use of locoregional analgesia evolved from none (control), to continuous bupivacaine infusion transversus abdominis plane and catheters, to single-dose transversus abdominis plane blockade with liposomal bupivacaine solution. Demographic factors, length of stay, inpatient opioid consumption, and complications were reported for all three groups. Results: One hundred twenty-eight consecutive patients (182 flaps) were identified. Forty patients (62 flaps) were in the infusion–liposomal bupivacaine group, 48 (66 flaps) were in the single-dose blockade–catheter group, and 40 (54 flaps) were in the control group. The infusion–liposomal bupivacaine patients had a significantly shorter hospital stay compared with the single-dose blockade–catheter group (2.65 ± 0.66 versus 3.52 ± 0.92 days; p 〈 0.0001) and the control group (2.65 ± 0.66 versus 4.05 ± 1.26 days; p 〈 0.0001). There was no significant difference in flap loss or major complications among groups. Conclusions: When used as part of a nonnarcotic postoperative pain regimen, transversus abdominis plane blocks performed with single injections of liposomal bupivacaine help facilitate early hospital discharge after abdominally based microsurgical breast reconstruction. A trend toward consistent discharge by postoperative day 2 was seen. This could result in significant cost savings for health care systems. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Abstract: Introduction: Gemcitabine/oxaliplatin (GemOx), with or without rituximab, is a frequently used treatment of relapsed or refractory (r/r) aggressive B-cell non-Hodgkin lymphoma (B-NHL), and is NCCN compendium-listed for both transplant-eligible and ineligible patients based upon results in small phase II clinical trials. Increasingly, GemOx is being accepted as a comparator arm for clinical trials in these populations. However, there is a paucity of observational data describing the effectiveness of R-GemOx in the treatment of r/r aggressive B-cell lymphoma. Methods: We conducted a retrospective analysis of the use of the GemOx regimen (with or without rituximab) in patients with r/r aggressive B-NHL at Memorial Sloan Kettering Cancer Center between January 2007 and January 2018, with a data cutoff of July 1, 2019. Data were extracted from the electronic medical record. Eligible diagnoses included diffuse large B-cell lymphoma and its subtypes (DLBCL); high-grade B-cell lymphomas (HGBL); transformed indolent B-cell lymphoma (tNHL) and grade 3B follicular lymphoma (FL3B). The primary objective of the study was to evaluate the activity of GemOx-based treatment in this patient population, as measured by overall response rate (ORR), complete response (CR) rate, progression-free survival (PFS), and overall survival (OS). CR was defined by a qualitatively negative 18-FDG-PET scan following completion of GemOx. PFS was defined as the time from start of therapy to disease progression or death, censoring patients at the time of initiation of any consolidative treatment. Similarly, OS was defined as the time from the start of GemOx until death or loss to follow-up. Results: Data were collected for 140 consecutive patients that received GemOx with (n=81) or without (n=59) rituximab in the treatment of a qualifying diagnosis (Table 1). Those treated had a median age at initiation of therapy of 69 (range, 30-92) and were predominantly male (58%). The median number of prior lines of therapy was 1 (range, 1-7), and the majority (97%) had received prior rituximab; few had received either prior autotransplant (11%) or allotransplant (1%). Regarding treatment delivered, the median number of cycles of therapy was 2 (range 1-12) with a mode of 2 (n=44, 31%). The ORR was 26% (n=37) with a CR rate of 15% (n=21). When evaluated by diagnosis, the ORR was 22% (n=19/88) in DLBCL, 40% (n=4/10) in HGBL, 35% (n=14/40) in tNHL, and 0% (n=0/2) in FL3B. Of the patients that responded to GemOx, 11 were successfully bridged to transplant (7 auto; 4 allo); two of those who went on to allotransplant had previously undergone autotransplant. Additionally, 3 patients went on to subsequently receive CAR-T therapy. Assessing the cohort overall, with a median follow-up of 48.1 months, PFS was only 1.4 months (95% CI: 1.3, 1.8), and median OS was 7.8 months (95% CI: 5.5, 12.0) (Figure 1). OS was longest for patients with tNHL at 10.2 months followed by DLBCL (7.5), HGBL (6.8) and FL3B (4.1) (Figure 2). Patients that received GemOx without rituximab in the setting of rituximab-refractory disease had a median OS of 4.1 months, less than that of 10.7 months for those receiving rituximab (p=0.052). However, there was no difference observed in PFS by inclusion of rituximab (1.6 months vs. 1.3 months, p=0.166). Patients with disease that was primary refractory following first-line therapy had a median OS of 4.5 months from initiation of GemOx, less than that of 10.8 months for patients that had achieved complete remission with first-line therapy (p=0.024). Patients that received GemOx as second-line therapy did not have a statistically significantly higher ORR (31% vs. 19%), OS (10.8 vs. 6.0 months), or PFS (1.7 vs, 1.4 months; all p=NS). In the subset of patients with DLBCL, there was again no significant difference in ORR (21% vs. 22%, p=NS), OS (8.5 vs. 6.1 months), or PFS (1.6 vs. 1.4 months; all p=NS). Conclusion: Despite compendium listing for both transplant-eligible and ineligible patients, and despite its adoption as a comparator arm in current and planned trials in r/r DLBCL, the real-world activity of GemOx with or without rituximab in the treatment of relapsed or refractory aggressive B-cell lymphoma is poor. Ongoing analysis is being conducted to seek clinical and histopathologic features associated with improved outcomes with GemOx.

Abstract: Nodal marginal zone lymphoma (NMZL) is a rare non-Hodgkin B-cell lymphoma that has historically been difficult to define, though is now formally recognized by the World Health Organization Classification. To better characterize the clinical outcomes of patients with NMZL, we reviewed a sequential cohort of 187 patients with NMZL to describe baseline characteristics, survival outcomes, and time-to-event data. Initial management strategies were classified into five categories: observation, radiation, anti-CD20 monoclonal antibody therapy, chemoimmunotherapy, or other. Baseline Follicular Lymphoma International Prognostic Index scores were calculated to evaluate prognosis. A total of 187 patients were analyzed. The five-year overall survival was 91% (95% confidence interval [CI] , 87-95), with a median follow-up time of 71 months (range, 8-253) among survivors. A total of 139 patients received active treatment at any point, with a median follow-up time of 56 months (range, 13-253) among survivors who were never treated. The probability of remaining untreated at five years was 25% (95% CI, 19-33). For those initially observed, the median time to active treatment was 72 months (95% CI, 49-not reached). For those who received at least one active treatment, the cumulative incidence of receiving a second active treatment at 60 months was 37%. Transformation to large B-cell lymphoma was rare, with a cumulative incidence of 15% at 10 years. In summary, our series is a large cohort of uniformly diagnosed NMZL with detailed analyses of survival and time to event analyses. We showed that NMZL commonly presents as an indolent lymphoma for which initial observation is often a reasonable strategy.
