Cardiac function in pediatric Ewing sarcoma during and after treatment: A longitudinal study.

BACKGROUND: While anthracycline therapy has been shown to improve outcomes in Ewing sarcoma, it may be associated with severe and even fatal cardiac dysfunction. We evaluated the burden and determinants of cardiac dysfunction in pediatric Ewing sarcoma (pES). METHODS: This retrospective study included children aged 0-18 years with pES treated at our center with the EFT 2001 protocol (anthracycline and cyclophosphamide containing regimen), with/without radiation therapy from January 2001 to December 2018. Cardiac dysfunction was defined as left ventricular (LV) ejection fraction with an absolute value <50%. RESULTS: Amongst 650 eligible patients (median age at diagnosis 12 years and median follow-up duration 69 months), 85 (13%) developed cardiac dysfunction, at a median 13 months (range: 1-168 months). The cumulative incidence of cardiac dysfunction was 5.7% at 12 months, 12% at 2 years, 13% at 3 years, 14% at 5 years, and 15 % at 10 years. At a median follow-up duration of 25 (range: 3-212) months, 21 (24.7%) patients had normalization of LV function, whereas nine (10.6%) patients died of cardiac causes. Older age at diagnosis (7-12 years OR 5.1, p = .01, 13-18 years, OR 3.9, p = .03), female sex (OR 2.3, p = .004), undernutrition (OR 2.9, p = .001), and chest wall location (OR 8.7, p = .08) were risk factors for cardiac dysfunction. CONCLUSIONS: Children with Ewing sarcoma have a high incidence of cardiac dysfunction, which continues to develop even years after therapy, underlining the need for life-long surveillance. Undernourished children are at a higher risk for cardiac dysfunction and need stringent monitoring.

Phase I Study Evaluating Dose De-escalation of Sorafenib with Metformin and Atorvastatin in Hepatocellular Carcinoma (SMASH).

BACKGROUND: This phase I dose de-escalation study aimed to assess the tolerability, safety, pharmacokinetics (PK), and efficacy of sequentially decreasing doses of sorafenib in combination (SAM) with atorvastatin (A, 10 mg) and metformin (M, 500 mg BD) in patients with advanced hepatocellular carcinoma (HCC). METHODS: Patients were enrolled in 1 of 4 sequential cohorts (10 patients each) of sorafenib doses (800 mg, 600 mg. 400 mg, and 200 mg) with A and M. Progression from one level to the next was based on prespecified minimum disease stabilization (at least 4/10) and upper limits of specific grade 3-5 treatment-related adverse events (TRAE). RESULTS: The study was able to progress through all 4 dosing levels of sorafenib by the accrual of 40 patients. Thirty-eight (95%) patients had either main portal vein thrombosis or/and extra-hepatic disease. The most common grade 3-5 TRAEs were hand-foot-syndrome (grade 2 and grade 3) in 3 (8%) and transaminitis in 2 (5%) patients, respectively. The plasma concentrations of sorafenib peaked at 600 mg dose, and the concentration threshold of 2400 ng/mL was associated with higher odds of achieving time to exposure (TTE) concentrations >75% centile (odds ratio [OR] = 10.0 [1.67-44.93]; P = .01). The median overall survival for patients without early hepatic decompensation (n = 31) was 8.9 months (95% confidence interval [CI]: 3.2-14.5 months). CONCLUSION: The SAM combination in HCC patients with predominantly unfavorable baseline disease characteristics showed a marked reduction in sorafenib-related side effects. Studies using sorafenib 600 mg per day in this combination along with sorafenib drug level monitoring can be evaluated in further trials.(Trial ID: CTRI/2018/07/014865).

A Retrospective Cohort Study to Evaluate the Outcomes of HIV-Associated High-Grade B-Cell Non-Hodgkin Lymphoma (NHL) Treated with Dose Adjusted EPOCH (+/-R) Regimen.

High-grade B-cell NHL's are more common in seropositive patients. They are biologically different from their seronegative counterparts. We report our analysis on our cohort of patients who were treated with DA-EPOCH(+/-R). We retrospectively analyzed treatment-naïve HIV-associated High-grade B-cell NHL patients (aged ≥ 18) treated with DA-EPOCH(+/-R) regimen from 2011 to 2015. Descriptive statistics were summarized with median and range; survival outcomes were analyzed with Kaplan-Meier method. The cohort comprised of 40 patients [DLBCL(19), Burkitt's Lymphoma(16), High-grade B-Cell Lymphoma-Unclassifiable(09), and Plasmablastic Lymphoma(01)] and the median CD4 + T cell count was 202/mm3. CNS prophylaxis was administered with intrathecal methotrexate to 90% of patients. With a median follow-up of 72 months, an estimated 5-year OS was 82.5%, and 5-PFS was 77.5%. There were 9 deaths, and 9 patients had progression. At least 4 cycles of chemotherapy were administered to 35 (93%) patients, with 28 (70%) receiving 6 cycles. Grade 3-4 toxicities were seen in 33 (83%) patients- febrile neutropenia (65%) being the most common followed by mucositis (25%) and peripheral neuropathy (13%). There was no difference in survival based on IPI, CD 4 + T cell count, CDI, or duration of HIV. DA-EPOCH(+/-R) is a highly effective regimen in seropositive high-grade B-cell lymphoma, even in the presence of adverse features.

Adjuvant Gemcitabine Plus Cisplatin and Chemoradiation in Patients With Gallbladder Cancer: A Randomized Clinical Trial.

Importance: There is limited evidence with regard to the benefit of adjuvant chemotherapy chemoradiotherapy in resected gallbladder cancers (GBCs). Objective: To establish a baseline survival rate for operated GBCs in patients receiving either gemcitabine plus cisplatin (GC) or capecitabine and capecitabine concurrent with chemoradiation (CCRT). Design, Setting, and Participants: The GECCOR-GB study was a multicenter, open-label, randomized phase 2 noncomparator "pick the winner" design trial of adjuvant GC and CCRT in patients with resected histologically confirmed adenocarcinoma or adenosquamous carcinoma of the gallbladder, (stage II/III) with no local residual tumor (R0) or microscopic residual tumor (R1). The study was carried out in 3 tertiary cancer institutions in India. Patients 18 years or older with adequate end-organ functions, and Eastern Cooperative Oncology Group Performance Status of 1 or lower between May 2019 and February 2022 were enrolled. The cutoff date for data analysis was February 28, 2023. Interventions: Patients were randomized 1:1 to receive either GC every 3 weeks (maximum of 6 cycles) or CCRT comprising capecitabine with concurrent chemoradiation (capecitabine concurrent with radiotherapy) sandwiched between capecitabine chemotherapy. Main Outcomes and Measures: The primary outcome was disease-free survival (DFS) at 1 year in randomized patients. This study was conducted as 2 parallel, single-stage phase 2 clinical trials. Within each treatment arm, a 1-year DFS rate of less than 59% was considered as insufficient activity, whereas a 1-year DFS rate of 77% or higher would be considered as sufficient activity. Results: With a median follow-up of 23 months, 90 patients were randomized, 45 in each arm. Overall, there were 31 women (69%) and 14 men (31%) in the GC arm with a mean (range) age of 56 (33-72) years and 34 women (76%) and 11 men (24%) in the CCRT group with a mean (range) age of 55 (26-69) years. In the GC and CCRT arms, 1-year DFS and estimated 2-year DFS was 88.9% (95% CI, 79.5-98.3) and 74.8% (95% CI, 60.4-89.2), and 77.8% (95% CI, 65.4-90.2) and 74.8% (95% CI, 59.9-86.3), respectively. Completion rates for planned treatment was 82% in the GC arm and 62% in the CCRT arm. Conclusions and Relevance: In this randomized clinical trial, GC and CCRT crossed the prespecified trial end points of 1-year DFS in patients with resected stage II/III GBCs. The results set a baseline for a larger phase 3 trial evaluating both regimens in operated GBCs. Trial Registration: ClinicalTrials.gov Identifier: CTRI/2019/05/019323I.

Outcomes of Cervical Cancer in HIV-Positive Women Treated With Radiotherapy at a Tertiary Care Center in India.

PURPOSE: There are limited data on management of cervical cancer in women living with HIV in the modern antiretroviral therapy era. The study aimed to evaluate outcomes and toxicities of these patients treated with radiotherapy. MATERIALS AND METHODS: A retrospective analysis of HIV-positive cervical cancer patients treated with radiotherapy between 2011 and 2018 was conducted at a tertiary care center in India. RESULTS: Eighty-two HIV-positive cervical cancer patients treated with radiotherapy were identified. Their median age was 45 years. Seventy-four (90%) patients received radiotherapy with curative-intent and eight patients received palliative radiotherapy. Median CD4 count at the start of treatment was 342 cells/mm3 (interquartile range: 241-531). Among patients planned for definitive radiotherapy, concurrent cisplatin was planned in 52 (70%) patients with a median of four chemotherapy cycles, and 81% (n = 60) patients received brachytherapy. Among patients who received brachytherapy, the median prescription dose was 80 Gy. Seventy-seven patients completed their prescribed treatment. At a median follow-up of 37 months, 3-year disease-free survival of patients planned with curative-intent was 54%. On multivariate analysis, treatment completion was associated with favorable disease-free survival. Grade III/IV acute gastrointestinal toxicity was seen in five (6.8%) patients, whereas 30% patients had grade III/IV acute hematologic toxicity. All these patients completed their planned radiotherapy with good supportive care. CONCLUSION: Standard treatment of chemoradiation should be planned in women living with HIV with well-managed HIV presenting with locally advanced cervical cancer. Our study highlights the need for optimal management of these patients by a multidisciplinary team with intensive supportive care to ensure completion of planned treatment to achieve better outcomes.
