Background/Objectives: The extent of initial surgical resection for low-risk papillary thyroid carcinoma (PTC) remains debated. Traditionally, total thyroidectomy (TT) has been the standard approach, although the 2015 American Thyroid Association (ATA) guidelines endorsed a more conservative strategy. The real-world adoption of these recommendations, however, is unclear. This study evaluated changes in the surgical management of low-risk PTC in a high-volume center following the implementation of the ATA guidelines and analyzed the impact on postoperative outcomes. Methods: We conducted a retrospective study of 1644 patients who underwent surgery for localized low-risk PTC < 4 cm between 2014 and 2023. Temporal trends in the initial surgical procedure (TT vs. thyroid lobectomy [TL]) were analyzed overall and by tumor size and patient demographics. The need for completion thyroidectomy after TL and postoperative outcomes were also assessed. Results: The use of TL increased from 0% in 2014 to 59.4% in 2023 (p < 0.001). For microcarcinomas, TL rose from 17.5% in 2016 to 78% in 2023, with similar but less pronounced trends for 1-2 cm tumors. TT remained predominant for nodules > 2 cm. The completion thyroidectomy rate declined from 32% in 2016 to 4% in 2022. Patients undergoing TT experienced higher rates of postoperative complications (12.4% vs. 3.0%), particularly transient hypoparathyroidism (8.9% vs. 0%), and permanent hypoparathyroidism (1.8% vs. 0%), as well as longer operative time and hospital stay (all p < 0.001). The incidence of hypoparathyroidism decreased over time as TL use increased. Conclusions: Adoption of the 2015 ATA guidelines has progressively increased the use of TL in the management of low-risk PTC. This shift in surgical practice is associated with a reduction in the overall postoperative complication burden at the population level, largely driven by decreased hypoparathyroidism. Although guideline uptake has been gradual, current trends suggest increasing acceptance of less aggressive surgical strategies in routine clinical practice.

Cervical cancer (CC) remains a leading cause of cancer-related mortality, particularly in low- and middle-income countries (LMICs), despite advancements in HPV vaccination and screening. Radiotherapy (RT) plays a critical role in managing CC, but conventional fractionated radiotherapy (CFRT) is limited by long treatment durations, which reduce patient adherence, increase the risk of treatment interruptions, and impair healthcare access in LMICs. Moderately hypofractionated radiotherapy (MHRT) may offer a promising alternative, delivering higher doses per fraction with fewer total fractions, thus shortening treatment duration and alleviating the burden on both patients and healthcare systems. Early clinical data suggest that MHRT achieve acceptable short- to medium-term tumor control with manageable toxicity. However, the small sample sizes and limited follow-up in published studies preclude definitive conclusions about long-term efficacy and safety. This review synthesizes the existing clinical evidence to outline the potential benefits and inherent limitations of MHRT in CC management and highlight the need for future large-scale, long-term randomized controlled trials with rigorous quality assurance protocols. These findings also have implications for the potential implementation of MHRT in LMICs.

Background: Ovarian cancer, the most lethal gynecologic malignancy, is characterized by a poor health-related quality of life (HRQoL). The present study examined the mediating role of self-perceived burden (SPB) in the impact of self-esteem on HRQoL and whether age moderated the associations among ovarian cancer patients. Methods: 203 patients effectively completed the Functional Assessment of Cancer Therapy-General (FACT-G), Rosenberg Self-Esteem Scale, and SPB scale, respectively. For the FACT-G, physical (PWB), social/family (SFWB), emotional (EWB), and functional well-being (FWB) were scored separately. Results: Significant mediation of SPB in the impacts of self-esteem on PWB (a × b = 0.074, 95% CI: 0.018, 0.153), EWB (a × b = 0.048, 95% CI: 0.001, 0.125), and FWB (a × b = 0.056, 95% CI: 0.009, 0.114) were revealed. Age positively moderated the impact of self-esteem on SPB (β = 0.159, p < 0.05), and the associations of SPB with PWB (β = 0.173, p < 0.05) and EWB (β = 0.240, p < 0.01), indicating a moderated mediation. Conclusions: Ovarian cancer patients' self-esteem could improve the PWB, EWB, and FWB domains of HRQoL by reducing SPB. Age could attenuate SPB's mediation in the impacts of self-esteem on PWB and EWB, indicating stronger impacts in younger patients. Clinical programs integrating components that strengthen self-esteem and reduce SPB may be particularly beneficial for younger women with ovarian cancer.

Patients with respiratory tract malignancies who undergo tracheostomy often experience profound psychosocial challenges related to visible anatomical changes and altered communication. The aim of this study was to evaluate psychosocial barriers and perceived social acceptance in patients living with a tracheostomy, compared with patients treated for similar cancers without requiring a tracheostomy. A matched case-control study with frequency matching at the group level was conducted including 150 patients with permanent tracheostomies and 150 matched controls treated with organ-preserving approaches. Groups were frequency-matched at the group level based on age, sex, primary tumor site, and disease stage at diagnosis. Participants completed a study-specific questionnaire assessing social withdrawal, self-consciousness, and perceived reactions of others using a five-point Likert scale. A composite Psychosocial Barrier Score was calculated, and subgroup analyses examined differences according to gender and age. Patients with tracheostomies demonstrated significantly higher psychosocial burden than controls, with markedly elevated composite scores and higher endorsement of stigma-related items. Female and younger patients within the tracheostomy group reported the greatest psychosocial difficulties, including increased social avoidance and reduced confidence in public settings. In contrast, gender- and age-related differences were minimal in the control group. These findings indicate that tracheostomy is strongly associated with heightened psychosocial barriers and perceived social stigma, particularly among younger and female patients. Integrating targeted psychosocial support into routine post-treatment care may be essential to improve social reintegration and quality of life in this population.

Background: The five-year survival rate of patients with ovarian cancer remains less than 50%, secondary to chemotherapy resistance. Purpose: This study aims to evaluate the effects of itraconazole as a supplementary treatment with paclitaxel and carboplatin on malignancy response and in preventing the initial development of chemoresistance in chemotherapy-naïve patients with advanced ovarian epithelial cancer. Method: This randomized placebo-controlled double-blind study involved 60 chemotherapy-naïve patients with advanced epithelial ovarian malignancy who were randomized into two arms; the placebo and itraconazole groups. The placebo group received six chemotherapy cycles and four inactive capsules, while the itraconazole group received six chemotherapy cycles and 400 mg oral itraconazole for five days per cycle. Results: Following completion of six chemotherapy cycles and when contrasted with the control arm, the itraconazole arm demonstrated statistically significant improvements in tumor response. The objective response rate was 80% in the itraconazole group compared with 47% in the placebo group (p = 0.015), while the disease control rate was 100% versus 80%, respectively (p = 0.023). The median progression-free survival (PFS), defined as the time point at which 50% of patients experienced disease progression or death, was 13.5 months for the overall study population. PFS was evaluated as a fixed-time endpoint at 18 months following completion of chemotherapy for the overall study population. Progression-free survival was significantly improved in the itraconazole group, with 70% of patients remaining progression-free compared with 26.7% in the placebo group (p = 0.001). Also, the itraconazole group produced significant declines in the serum levels of CA-125 (p = 0.005) and p-glycoprotein (p = 0.042) with significant elevation in VEGFR-2 (p = 0.006) as compared to the control group. Itraconazole was safe and its use was associated with a significant improvement in the quality of life (QOL). Conclusions: Itraconazole could represent a promising add-on therapy to enhance tumor response to chemotherapy in patients with ovarian cancer.

The management strategies in resectable non-small cell lung cancer (NSCLC) have changed over the last few years. Despite advancements in surgical techniques and conventional chemotherapy, patients with resectable NSCLC remained at high risk of future recurrence. Clinical trials have demonstrated improvements in response rates, pathological outcomes, and survival with the perioperative approach. Considering the findings of these landmark trials, there is a pressing need to contextualize and incorporate these global developments into the national practice framework. This review outlines key developments from recent clinical trials, with a focus on perioperative strategies in early-stage operable NSCLC from a Canadian perspective. We discuss the integration of checkpoint inhibitors in the perioperative setting for patients without actionable genomic alterations, adjuvant targeted therapies for EGFR and ALK mutant disease, and emerging tools such as ctDNA based minimal residual disease monitoring. The article also addresses the practical challenges of implementing these advances within the Canadian healthcare system, including systemic therapy approvals, barriers, and importance of multidisciplinary care to guide clinicians in optimizing patient outcomes.

As treatments for multiple myeloma (MM) evolve, there is a need for real-world insights into treatment patterns and outcomes. The treatment practices and clinical outcomes in patients with MM (TOTEMM) was a database study (2018-2024) of newly diagnosed transplant-ineligible patients with MM in Argentina (TOTEMM-A) and Brazil (TOTEMM-B) in a private healthcare setting. In TOTEMM-A (n = 72) and TOTEMM-B (n = 892), 37 and 92 different drug regimens were reported, respectively. In each country, treatment duration reduced across lines of therapy (LOT) (TOTEMM-A: range, 6.2-3.4 months; TOTEMM-B: range, 4.4-3.5 months); attrition rates increased across LOT (TOTEMM-A: range, 52.8-86.1%; TOTEMM-B: range, 41.9-88.0%); triplet regimens (mainly bortezomib based) were used most frequently in first-line (1L); >75% relapsed within 12 months, regardless of the drug prescribed; over 90% of relapses occurred between 1L and second-line, and up to half of patients were rechallenged with the same drug; >65% of patients experienced disease progression after 1L; and the 1- to 5-year adjusted cumulative risk of progression or death increased across LOT (TOTEMM-A: range, 47.1-88.5%; TOTEMM-B: range, 40.4-91.7%). The rapid and marked progression underscores the urgent need for novel treatments and regimens.

Glioblastoma is currently an incurable disease despite the development of a wide variety of therapeutic approaches, from surgical methods to immunotherapy. In current clinical practice, treatment typically involves a combination of existing methods, often comprising three stages: tumor resection, radiotherapy, and chemotherapy. Modern research offers improved chemotherapy strategies, as well as combinations of chemotherapy with immunotherapy. However, the efficacy of these therapies is profoundly influenced by factors such as tumor and peritumoral heterogeneity, alongside complex molecular signaling pathways. Optimizing glioma treatment requires a rigorous mechanistic understanding of individual approaches and their synergistic effects. This review comprehensively details current glioblastoma therapeutic strategies and critically evaluates key reference models for assessing combination therapy efficacy and their inherent limitations. A deeper understanding of these mechanisms and models will refine the investigation of observed therapeutic effects and accelerate the translation of promising in vitro approaches to effective clinical management of malignant gliomas.

Advanced-stage epithelial ovarian cancer (EOC) is defined by biological heterogeneity and poor outcomes, and traditional survival metrics fail to reflect the evolving nature of prognosis as patients survive longer. This study aimed to evaluate conditional survival (CS) in advanced EOC using both overall survival (OS) and progression-free survival (PFS) metrics to provide a dynamic understanding of long-term outcomes. We retrospectively analyzed 808 patients with FIGO stage III-IV EOC who underwent surgery at Baskent University Ankara Hospital between 2004 and 2024. CS estimates were calculated for additional 1- and 5-year intervals among patients who had already survived 6 months, 1, 3, or 5 years after surgery. Median OS and PFS were 4.37 and 1.70 years, respectively. Peritoneal dissemination and platinum resistance were independent predictors of poor survival. Approximately 11% of patients achieved survival beyond ten years. The 1-year CS-OS increased from 87% at 6 months to 95% at 5 years, while the 5-year CS-OS rose from 49% to 66%; corresponding CS-PFS values increased from 89% to 95% and from 44% to 62%. Conditional survival analysis underscores that prognosis in advanced ovarian cancer is not static but continually improves with time survived and sustained disease control. These insights redefine long-term outcomes and provide a modern foundation for individualized patient counseling and survivorship planning.

Personalized cancer treatment depends on the accurate and timely detection of the patient tumor variants. LBx enables minimally invasive tumor mutation profiling. We report results of a pan-Canadian LBx program for patients with advanced solid tumors. Plasma samples were tested at Imagia Canexia Health accredited laboratory using the clinically validated Follow It 38-gene panel. A proprietary platform was used to identify clinically relevant variants in the circulating tumor DNA and report results following accepted international guidelines on clinical significance. A total of 4229 eligible patients submitted samples for LBx testing, and reports for 97% of them were delivered within ~8 days. More than 80% of Canadian oncologists from >150 institutions across 12 provinces (11% from rural centers) participated in the project. The patient cohort consisted mostly of advanced or metastatic lung, breast, and colon cancers. ctDNA mutations were detected in >50% of cases, and clinical trials were recommended for 76% of all participants. Health economics modeling analysis found that Follow It^® in combination with tissue biopsy was cost-saving and resulted in an additional 0.1138 QALYs gained relative to tissue biopsy alone. The successful pan-Canadian implementation of a cost-effective, robust LBx testing program demonstrated its sustained demand and feasibility, and its potential economic and health benefits.
