Purpose: This manuscript reports the results of the Indian Network for Development of Peritoneal Surface Oncology and Indian Society of Peritoneal Surface Malignancies (INDEPSO-ISPSM) consensus that aimed to provide recommendations for some important aspects management of patients with colorectal peritoneal metastases (CPM) and address some issues unique to India.

Methods: The modified Delphi technique was used with two rounds of voting. There were 29 questions on nine main topics-the role of cytoreductive surgery (CRS), patient selection for CRS, preoperative workup, role of systemic chemotherapy (SC), CPM with other visceral metastases, molecular profile, hyperthermic intraperitoneal chemotherapy (HIPEC) and other modalities of intraperitoneal chemotherapy (IPC), prophylactic/preventive strategies, and surveillances after CRS. A consensus was achieved if anyone option received >70 votes (strong consensus >90%).

Results: Forty-eight surgical (n = 41) and gastrointestinal (n = 7) oncologists were invited; 44 agreed to participate. The response rate was 95.4% (42/44) in round 1 and 93.1% (41/44) in round 2. Overall, a consensus was achieved on 23/29 (79.3%) questions (strong consensus on 6/29 [20.6%]). The panel strongly recommended considering surgery for limited CPM with limited liver metastases (92.5%), not altering the surgical approach in patients with KRAS mutations (91.67%), and limiting the use of IPC for unresectable CPM outside clinical trials (95%). Adjuvant SC was recommended for all patients undergoing CRS (89.47%). CRS is a therapeutic option for selected patients with CPM including those with metachronous CPM (79.49) and signet ring cell cancers (76.92%). HIPEC was recommended outside clinical trials only for patients with peritoneal cancer index 11-15(80%).

Conclusion: The panel recommended CRS for most indications but was very selective in recommending HIPEC and IPC outside clinical trials. These recommendations should be a useful resource in clinical decision making for clinicians treating CPM in India and regions with a similar sociodemographic background.

Cancer remains a widespread and significant global health issue, with consequential impacts on individuals, families, and societies across the globe. Although there have been noteworthy advancements in the prevention, diagnosis, treatment, and study of cancer, the impact of this disease continues to be significant on health care systems and people worldwide. Furthermore, there are still differences in obtaining the advantages of modern cancer treatment, which can partly be attributed to the lack of standardized standards for providing top-notch cancer care. To tackle these difficulties, a multitude of projects and organizations have emerged to address the standard of cancer care on a global level. This paper provides a comprehensive review and analysis of the worldwide influence of programs and organizations that seek to improve the quality of cancer care. This document examines the progression of these initiatives, their cooperation with international organizations, possible paths for additional advancement, and suggestions for enhancing the standard of cancer treatment worldwide.

Purpose: Targeted therapies are indicated for patients with non-small cell lung cancer (NSCLC) and driver tumor mutations. However, real-world studies on the survival benefits of these agents are limited. This study aimed to evaluate the effect of targeted therapies matched to a genomic alteration on the survival of patients with NSCLC.

Methods: This retrospective study included 446 patients with advanced NSCLC who underwent next-generation sequencing between 2016 and 2023 at the Instituto Nacional de Cancerología in Mexico. The primary outcomes were progression-free survival (PFS) and overall survival (OS).

Results: For the entire cohort, the PFS and OS were 10.71 months (95% CI, 9.35 to 12.06) and 47.77 months (95% CI, 29.67 to 65.86). PFS was significantly longer in patients with actionable mutations treated with targeted therapies (19.41 months [95% CI, 14.27 to 24.55]; P < .001) than in patients without actionable mutations (6.4 months [95% CI, 4.4 to 8.4]) or not treated with targeted therapies (6.6 months [95% CI, 5.3 to 7.89]). Similarly, OS was significantly longer in patients with actionable mutations treated with targeted therapies (89.69 months [95% CI, 45.54 to 133.84]; P < .001) than in patients without actionable mutations (17.11 months [95% CI, 8.65 to 25.57]) or not treated with targeted therapies (22.3 months [95% CI, 12.48 to 32.1]). Survival gains were driven by significant improvements in PFS and OS in patients with EGFR and ALK mutations.

Conclusion: This real-world data analysis demonstrated that targeted therapies improve the survival of patients with NSCLC with actionable mutations, which supports a recommendation for widening access to broad-based genomic testing and targeted therapies.

Purpose: Breast cancer (BC) is the most common female cancer worldwide, and the burden is increasing across sub-Saharan Africa. For women with hormone receptor-positive (HR+) cancers, endocrine therapy (ET) taken for 5-10 years can reduce the risk of recurrence by half. We explored experiences with ET and barriers to utilization among survivors in Botswana.

Methods: We recruited women with nonmetastatic disease from a survivorship cohort who had undergone mastectomy within 1-5 years for semi-structured interviews to explore experiences with treatment. This thematic content analysis focused on ET, so the sample included women with HR+ cancer who should have received ET and HR- women who reported taking ET.

Results: We analyzed interviews with 19 women (mean age 54 years, 42% stage I/II, 58% stage III). Three key themes were identified: (1) limited provider counseling, (2) challenges refilling prescriptions at public pharmacies, and (3) high medication and transportation costs associated with private pharmacies. Subthemes included immunohistochemistry result communication, lack of knowledge, frequent public pharmacy stockouts, inconvenient prescription refill policies, and medication switching and discontinuation, especially among participants with low socioeconomic positions (SEPs). Women's persistence, SEP, and financial support facilitated refills. Although some experienced side effects, they were not a common reason for discontinuation.

Conclusion: BC survivors in Botswana face multilevel barriers to accessing and adhering to ET. Provider and health system improvements are needed to effectively communicate ET importance and increase access to consistently available and affordable medication.

Purpose: The burden of cervical cancer in India is enormous, with more than 60,000 deaths being reported in 2020. The key intervention in the WHO's global strategy for the elimination of cervical cancer is to aim for the treatment and care of 90% of women diagnosed with cervical lesions. The current screen-and-treat approach as an option for resource-limited health care systems where screening of the cervix with visual inspection with acetic acid application (VIA) is followed by immediate ablative treatment by nurses in the case of a positive test. This approach often results in overtreatment, owing to the subjective nature of the test. Unnecessary treatments can be diminished with the use of emerging computer-assisted visual evaluation technology, using artificial intelligence (AI) tool to triage VIA-positive women. The aim of this study was (1) to develop a VIA-AI tool using cervical images to identify and categorize the VIA-screen-positive areas for eligibility and suitability for ablative treatment, and (2) to understand the efficacy of the VIA-AI tool in guiding the nurses to decide on treatment eligibility in the screen-and-treat cervical screening program.

Methods: This was an exploratory, interventional study. The VIA-AI tool was developed using deep-learning AI from the image bank collected in our previously conducted screening programs. This VIA-AI tool was then pilot-tested in an ongoing nurse-led VIA screening program.

Results: A comparative assessment of the cervical features performed in all women using the VIA-AI tool showed clinical accuracy of 76%. The perceived challenge rate for false positives was 20%.

Conclusion: This novel cervical image-based VIA-AI algorithm showed promising results in real-life settings, and could help minimize overtreatment in single-visit VIA screening and treatment programs in resource-constrained situations.

Purpose: Trimodal therapy (TMT) is the standard treatment for patients with nonmetastatic inflammatory breast cancer (IBC). TMT consists of neoadjuvant systemic therapy, modified radical mastectomy (MRM), and postmastectomy radiation therapy. Although broadly considered the best approach for IBC, in the United States, only a third of patients receive TMT. The rate is unknown in low- and middle-income countries (LMICs).

Methods: A questionnaire in English and Spanish was constructed to assess the awareness, knowledge, and treatment patterns of IBC among providers in LMICs. It was emailed to the ONCOLLEGE global oncology collaborative group (a network of cancer care providers practicing in LMICs) and through other oncology network providers in LMICs, enhancing the sample size through a snowball sampling approach.

Results: Between June and December of 2023, 145 participants completed the questionnaire, of whom 112 respondents were from 36 LMICs. All the providers reported that standard chemotherapy and MRM were available in their practice; 99.5% responded that radiation therapy was available. A total of 74.1% appropriately reported that IBC is a clinical diagnosis, although 51.8% stated that pathologic evidence of lymphatic emboli was required for IBC diagnosis. A third of the providers responded that >90% of their patients undergo all three parts of TMT.

Conclusion: Many patients with IBC in LMICs are not receiving TMT. Barriers to diagnosis and treatment were at least partially related to limited providers' comfort level and knowledge, suggesting that educational approaches can be impact-oriented interventions. On the basis of our findings, we created educational material, which will be translated into various languages and disseminated broadly to improve providers' awareness and knowledge of IBC.

Purpose: Biliary tract cancers (BTCs) are usually diagnosed in advanced stages, where treatment options are either palliative chemotherapy and/or best supportive care. The breakthrough results of the TOPAZ-1 trial demonstrated a 24% decrease in risk of death at 2 years with the addition of durvalumab to chemotherapy.

Materials and methods: This was a multicenter retrospective cohort study conducted across 14 institutions in India. All the patients were diagnosed with advanced BTCs. The primary objective was to assess median overall survival (mOS) with the use of durvalumab in combination with chemotherapy backbone. The patient details, treatment details, laboratory results, and outcome parameters were recorded from the prospectively collected databases.

Results: A total of 148 patients were included with a median age of 57.5 years; 36 (24.3%) patients had borderline Eastern Cooperative Oncology Group performance status ≥2. The most common subtype was gall bladder cancer (GBC), seen in 94 patients (63.5%); 126 (85.1%) patients presented with de novo metastases. At a median follow-up of 6.8 months (95% CI, 5.9 to 7.8), the estimated mOS for the entire cohort was 12 months (95% CI, 7.8 to 16.3) and median progression-free survival was 8.2 months (95% CI, 7.1 to 9.4) with objective response achieved in 44 (29.7%) patients, and the estimated 2-year OS being 25%. Immune-related grade 3/4 adverse events were reported in 11 (7.4%) patients. In multivariate analysis, age <60 years (P = .001) and standard dose of durvalumab (P < .001) were found to have improved OS compared with age >60 years and low dose of durvalumab.

Conclusion: To our knowledge, these real-world data provide the first evidence in Indian context of the efficacy and safety of durvalumab plus chemotherapy in patients with advanced/metastatic BTCs especially in GBC.
