RESUMO
The downstream effects on healthcare delivery during the initial wave of the COVID-19 pandemic remain unclear. The purpose of this study was to determine how the healthcare environment surrounding the pandemic affected the oncologic care of patients diagnosed with esophageal cancer. This was a retrospective cohort study evaluating patients in the National Cancer Database (2019-2020). Patients with esophageal cancer diagnoses were divided into pre-pandemic (2019) and pandemic (2020) groups. Patient demographics, cancer-related variables, and treatment modalities were compared. Among 26,231 esophageal cancer patients, 14,024 patients (53.5%) were in the pre-pandemic cohort and 12,207 (46.5%) were in the pandemic cohort. After controlling for demographics, patients diagnosed during the pandemic were more likely to have poorly differentiated tumors (odds ratio [OR] 1.24, 95% confidence interval [CI] 1.08-1.42), pathologic T3 disease compared to T1 (OR 1.25, 95% CI 1.02-1.53), positive lymph nodes on pathology (OR 1.36, 95% CI 1.14-1.64), and to be pathologic stage IV (OR 1.51, 95% CI 1.29-1.76). After controlling for oncologic characteristics, patients diagnosed during the pandemic were more likely to require at least two courses of systemic therapy (OR 1.78, 95% CI 1.48-2.14) and to be offered palliative care (OR 1.13, 95% CI 1.04-1.22). While these patients were offered curative therapy at lower rates, this became non-significant after risk-adjustment (p = .15). The pandemic healthcare environment was associated with significantly increased risk-adjusted rates of patients presenting with advanced esophageal cancer. While this led to significant differences in treatment, most of these differences became non-significant after controlling for oncologic factors.

BACKGROUND: Socioeconomic status (SES) is associated with a range of health outcomes, including cancer diagnosis and survival. However, the evidence for this association is inconsistent between countries with and without single-payer health care systems. In this study, the relationships between neighborhood-level income, cancer stage at diagnosis, and cancer-specific mortality in Alberta, Canada, were evaluated. METHODS: The Alberta Cancer Registry was used to identify all primary cancer diagnoses between 2010 and 2020. Average neighborhood income was determined by linking the Canadian census to postal codes and was categorized into quintiles on the basis of income distribution in Alberta. Multivariable multinomial logistic regression was used to model the association between income quintile and stage at diagnosis, and the Fine-Gray proportional subdistribution hazards model was used to estimate the association between SES and cancer-specific mortality. RESULTS: Out of the 143,818 patients with cancer included in the study, those in lower income quintiles were significantly more likely to be diagnosed at stage III (odds ratio [OR], 1.07; 95% CI [confidence interval], 1.06-1.09) or IV (OR, 1.12; 95% CI, 1.11-1.14) after adjusting for age and sex. Lower income quintiles also had significantly worse cancer-specific survival for breast, colorectal, liver, lung, non-Hodgkin lymphoma, oral cavity, pancreas, and prostate cancers. CONCLUSIONS: Disparities were observed in cancer outcomes across neighborhood-level income groups in Alberta, which demonstrates that health inequities by SES exist in countries with single-payer health care systems. Further research is needed to better understand the underlying causes and to develop strategies to mitigate these disparities.

BACKGROUND: Despite randomized trials demonstrating a mortality benefit to low-dose computed tomography screening to detect lung cancer, uptake of lung cancer screening (LCS) has been slow, and the benefits of screening remain unclear in clinical practice. METHODS: This study aimed to assess the impact of screening among patients in the Veterans Health Administration (VA) health care system diagnosed with lung cancer between 2011 and 2018. Lung cancer stage at diagnosis, lung cancer-specific survival, and overall survival between patients with cancer who did and did not receive screening before diagnosis were evaluated. We used Cox regression modeling and inverse propensity weighting analyses with lead time bias adjustment to correlate LCS exposure with patient outcomes. RESULTS: Of 57,919 individuals diagnosed with lung cancer in the VA system between 2011 and 2018, 2167 (3.9%) underwent screening before diagnosis. Patients with screening had higher rates of stage I diagnoses (52% vs. 27%; p ≤ .0001) compared to those who had no screening. Screened patients had improved 5-year overall survival rates (50.2% vs. 27.9%) and 5-year lung cancer-specific survival (59.0% vs. 29.7%) compared to unscreened patients. Among screening-eligible patients who underwent National Comprehensive Cancer Network guideline-concordant treatment, screening resulted in substantial reductions in all-cause mortality (adjusted hazard ratio [aHR], 0.79; 95% confidence interval [CI], 0.67-0.92; p = .003) and lung-specific mortality (aHR, 0.61; 95% CI, 0.50-0.74; p < .001). CONCLUSIONS: While LCS uptake remains limited, screening was associated with earlier stage diagnoses and improved survival. This large national study corroborates the value of LCS in clinical practice; efforts to widely adopt this vital intervention are needed.

BACKGROUND: We sought to determine the impact of historical redlining on travel patterns and utilization of high-volume hospitals (HVHs) among patients undergoing complex cancer operations. METHODS: The California Department of Health Care Access and Information database was utilized to identify patients who underwent esophagectomy (ES), pneumonectomy (PN), pancreatectomy (PA), or proctectomy (PR) for cancer between 2010 and 2020. Patient ZIP codes were assigned Home Owners' Loan Corporation grades (A: 'Best'; B: 'Still Desirable'; C: 'Definitely Declining'; and D: 'Hazardous/Redlined'). A clustered multivariable regression was used to assess the likelihood of patients undergoing surgery at an HVH, bypassing the nearest HVH, and total real driving time and travel distance. RESULTS: Among 14,944 patients undergoing high-risk cancer surgery (ES: 4.7%, n = 1216; PN: 57.8%, n = 8643; PD: 14.4%, n = 2154; PR: 23.1%, n = 3452), 782 (5.2%) individuals resided in the 'Best', whereas 3393 (22.7%) individuals resided in redlined areas. Median travel distance was 7.8 miles (interquartile range [IQR] 4.1-14.4) and travel time was 16.1 min (IQR 10.7-25.8). Overall, 10,763 (ES: 17.4%; PN: 76.0%; PA: 63.5%; PR: 78.4%) patients underwent surgery at an HVH. On multivariable regression, patients residing in redlined areas were less likely to undergo surgery at an HVH (odds ratio [OR] 0.67, 95% confidence interval [CI] 0.54-0.82) and were more likely to bypass the nearest hospital (OR 1.80, 95% CI 1.44-2.46). Notably, Medicaid insurance, minority status, limited English-language proficiency, and educational level mediated the disparities in access to HVH. CONCLUSION: Surgical disparities in access to HVH among patients from historically redlined areas are largely mediated by social determinants such as insurance and minority status.

Two methods for administering general anaesthesia are widely used: propofol-based total intravenous anaesthesia (propofol-TIVA) and inhalation volatile agent-based anaesthesia. Both modalities, which have been standards of care for several decades, boast a robust safety profile. Nevertheless, the potential differential effects of these anaesthetic techniques on immediate, intermediate, and extended postoperative outcomes remain a subject of inquiry. We discuss a recently published longitudinal analysis stemming from a multicentre randomised controlled trial comparing sevoflurane-based inhalation anaesthesia with propofol-TIVA in older patients with cancer, which showed a reduced incidence of emergence and postoperative delirium, comparable postoperative complication rates within 30 days after surgery, and comparable long-term survival rates. We undertake an assessment of the trial's methodological strengths and limitations, contextualise its results within the broader scientific evidence, and explore avenues for resolving the extant controversies in anaesthetic choice for cancer surgery. We aim to pave the way for the incorporation of precision medicine paradigms into the evolving landscape of perioperative care for patients with cancer.

BACKGROUND: Increasing evidence suggests that diabetes increases the risk of developing different types of cancer. Hyperinsulinemia, hyperglycemia and chronic inflammation, characteristic of diabetes, could represent possible mechanisms involved in cancer development in diabetic patients. At the same time, cancer increases the risk of developing new-onset diabetes, mainly caused by the use of specific anticancer therapies. Of note, diabetes has been associated with a â¼10% increase in mortality for all cancers in comparison with subjects who did not have diabetes. Diabetes is associated with a worse prognosis in patients with cancer, and more recent findings suggest a key role for poor glycemic control in this regard. Nevertheless, the association between glycemic control and cancer outcomes in oncologic patients with diabetes remains unsettled and poorly debated. PURPOSE: The current review seeks to summarize the available evidence on the effect of glycemic control on cancer outcomes, as well as on the possibility that timely treatment of hyperglycemia and improved glycemic control in patients with cancer and diabetes may favorably affect cancer outcomes.
RESUMO
OBJECTIVE: To report the 5-year failure-free survival (FFS) following high-intensity focused ultrasound (HIFU). PATIENTS AND METHODS: This observational cohort study used linked National Cancer Registry data, radiotherapy data, administrative hospital data and mortality records of 1381 men treated with HIFU for clinically localised prostate cancer in England. The primary outcome, FFS, was defined as freedom from local salvage treatment and cancer-specific mortality. Secondary outcomes were freedom from repeat HIFU, prostate cancer-specific survival (CSS) and overall survival (OS). Cox regression was used to determine whether baseline characteristics, including age, treatment year, T stage and International Society of Urological Pathology (ISUP) Grade Group were associated with FFS. RESULTS: The median (interquartile range [IQR]) follow-up was 37 (20-62) months. The median (IQR) age was 65 (59-70) years and 81% had an ISUP Grade Group of 1-2. The FFS was 96.5% (95% confidence interval [CI] 95.4%-97.4%) at 1 year, 86.0% (95% CI 83.7%-87.9%) at 3 years and 77.5% (95% CI 74.4%-80.3%) at 5 years. The 5-year FFS for ISUP Grade Groups 1-5 was 82.9%, 76.6%, 72.2%, 52.3% and 30.8%, respectively (P < 0.001). Freedom from repeat HIFU was 79.1% (95% CI 75.7%-82.1%), CSS was 98.8% (95% CI 97.7%-99.4%) and OS was 95.9% (95% CI 94.2%-97.1%) at 5 years. CONCLUSION: Four in five men were free from local salvage treatment at 5 years but treatment failure varied significantly according to ISUP Grade Group. Patients should be appropriately informed with respect to salvage radical treatment following HIFU.
RESUMO
OBJECTIVE: With advancements in medicine and technology, more people are surviving cancers. However, cancer mortality in Nigeria remains high. The yearly estimate is 72,000 cancer-related deaths, making cancer one of the leading causes of death in Nigeria. The current study aimed to identify and synthesize factors that facilitate or hinder cancer survivorship in Nigeria and add to our understanding of the patterns of cancer survivorship in LMICs, such as Nigeria. METHOD: Following preferred reporting items for systematic reviews and meta-analyses guidelines, a systematic review was conducted across PubMed, Cochrane, and Scopus databases. We identified 31 peer-reviewed studies that examined cancer treatment, management, care, and survivorship in Nigeria. RESULTS: Eight themes emerged from 31 peer-reviewed studies that examined the factors that facilitate or hinder cancer survivorship among Nigerians. They include themes such as self-care and management, treatment options, availability of pseudo-doctors/pharmacists, and the desire to live. The themes were further grouped into three overarching themes: psychosocial, economic, and health care. CONCLUSION: Cancer survivors in Nigeria face many unique experiences that impact their health outcomes and chances of survivorship. Therefore, understanding cancer survivorship in Nigeria must involve studies on diagnosis, treatment, remission, surveillance, after-cancer care, and end-of-life. With enhanced support, cancer survivors will have improved health, thereby reducing the cancer mortality rate in Nigeria.

BACKGROUND AND AIMS: Significantly discrepant survival rates have been documented in single disease childhood cancer cohorts in South Africa; those from higher socioeconomic groups were shown to have a significantly lower risk of death than those from less affluent households. This study aimed to determine the impact of socioeconomic status (SES) on childhood cancer survival using pooled South African data. METHODS: Five databases spanning January 2000 to December 2021 were interrogated. SES status was assigned based on a public sector annual household income classification. H0 households (formally unemployed) received free healthcare. H1, H2 and H3 (annual income > United States Dollar [USD] 19,000) households paid for healthcare relative to their income. The Spearman test assessed correlations between SES and disease stage in patients with solid tumours. Hazard ratios were determined using Cox regression modelling. The Kaplan-Meier procedure estimated overall survival (OS). RESULTS: A total of 1598 children were eligible for analysis; 1269 had a solid tumour with a negative correlation between SES and stage (Spearman rho = -.178; p < .001). Patients with solid tumours and lower SES showed proportionately higher numbers of stage III and IV disease (p < .01). This proportion decreased with higher SES categories. In the multivariate analyses adjusted for sex, age, tumour type and stage, higher SES was associated with lower mortality risk (p < .001), indicating that the impact of SES on survival was in excess of any effect that could be explained by lower stage disease alone. There was a strong positive correlation between race and SES (Fisher's exact tests, p < .001) across all groups and all SES strata. Five-year OS was 85.3% in children from H3 households versus 46.3% in children from H0 households (p < .001). CONCLUSION: SES significantly impacts childhood cancer survival for children with solid tumours in South Africa. SES is a robust surrogate for race in South Africa as a prognostic metric of disease outcome in childhood cancer. Advocacy to increase social support for impoverished patients is essential to achieve equitable improvements in outcomes treated with standardised national treatment guidelines.
RESUMO
PURPOSE: While significant progress in metastatic breast cancer (MBC) treatment has prolonged survival and improved prognosis, there remain substantial gaps in providing patient-centered supportive care. The specific care delivery needs for metastatic cancer differ from that of early-stage cancer due to the incurable nature and lifelong duration of the condition. The objective of this study was to assess how patients living with MBC would re-imagine cancer care delivery. METHODS: This qualitative study was conducted in partnership with patient-led organizations Guiding Researchers and Advocates to Scientific Partnerships (GRASP) and Project Life, a nonprofit, online wellness community founded by patients with MBC for patients living with MBC. Virtual semi-structured interviews (n = 36) were conducted with Project Life members purposively sampled from the groups' overall membership. The interview guide contained items surrounding patients' lived experiences of MBC, greatest unmet needs related to care, and perspectives on virtual wellness community involvement. Interviews were coded using two-stage deductive and inductive analysis. RESULTS: Three major themes for re-imagining cancer care delivery were identified, including holistic care, information needs, and conceptual shifts. Within these several subthemes emerged with patients re-imagining referrals to non-oncological services, caregiver support, acceptance of integrative medicine, streamlined clinical trial enrollment, curated quality patient resources, MBC-specific terminology and approaches, long-term life and goal-of-care planning, and patient-centered voice throughout. CONCLUSION: People living with metastatic cancers have specific supportive care needs. These findings highlight patient-driven areas for re-imagination that are most salient for individuals with MBC.

Understanding racial disparities in cancer outcomes continues to be a challenge, with likely many factors at play, including socioeconomic factors and genetic polymorphisms impacting basic cellular and molecular functions. Additionally, it is possible that specific combinations of environment and genetics have specific impacts. T-cell receptor (TCR) gene segment usage, HLA allele combinations have been associated with autoimmune and infectious disease courses, and more recently, TCR gene segment usage, HLA allele combinations have been associated with distinct survival outcomes in cancer as well. We examined several such, previously reported cancer-related TCR gene segment usage, HLA allele combinations for evidence of racial disparities, with regard to the prevalence of the combination in different racial groups. Results indicated that TCR gene segment usage, potentially reflecting environmental factors related to previous pathogen exposure, in combination with certain HLA alleles or independently, may represent a novel explanation for racial disparities in cancer outcomes. Overall, at this point, a genetic connection to racial disparities in cancer outcomes is detectable but remains modest, suggesting that other factors, such as socioeconomic factors, remain as important considerations.

OBJECTIVE: To compare the overall survival and disease-free survival rates with perioperative or adjuvant chemotherapy regimens in operable gastric cancer cases. METHODS: The retrospective, observational study was conducted at the Shaukat Khanum Memorial Cancer Hospital and Research Centre, Lahore, Pakistan, and comprised date from January 2015 to December 2020 of operable gastric cancer patients who had perioperative or adjuvant chemotherapy. Overall survival and disease-free survival were evaluated. Data was analysed using SPSS 23. RESULTS: Of the 108 patients in the aga range 27-80 years, 71(65.74%) were males. The overall median age was 49.50 years (interquartile range: 28 years). There were 69(63.88%) patients on perioperative and 39(36.12%) on adjuvant chemotherapy. The probability of 2- and 3-year overall survival was 68.20% and 57.32% in the perioperative group, and 51.09% and 45.43%, respectively, in the adjuvant group. The probability of 2- and 3-year disease-free survival was 55.45% and 49.30% in the perioperative group, while 2-year disease-free survival was 38.39% in the adjuvant group which had no patient reaching the 3-year mark. The median overall survival for the perioperative group was 49.29 months (interquartile range: 44.50 months) and for the adjuvant group it was 28.23 months (interquartile range: 25.00months) (p=0.07). The median disease-free survival was 35.46 months (interquartile range: 38.50 months) for the perioperative group and 10.19 months (interquartile range: 14.00months) for adjuvant group (p=0.16). The difference between the groups was not significant (p>0.05), but there was a trend suggestive of the superiority of perioperative chemotherapy over adjuvant chemotherapy. CONCLUSIONS: In operable gastric cancer cases, the difference between the groups was not significant, but there was a trend suggestive of the superiority of perioperative chemotherapy over adjuvant chemotherapy with respect to overall survival and disease-free survival.

Background and Objectives: It remains unclear which domains of preoperative health-related quality of life (HRQOL) and mental health are predictive of postoperative clinical and patient-reported outcomes in colorectal cancer (CRC) patients. Materials and Methods: A prospective cohort of 78 CRC patients undergoing elective curative surgery was recruited. The EORTC QLQ-C30 and HADS questionnaires were administered preoperatively and one month after surgery. Results: Preoperative cognitive functioning scores (95% CI 0.131-1.158, p = 0.015) and low anterior resection (95% CI 14.861-63.260, p = 0.002) independently predicted poorer 1-month postoperative global QOL. When postoperative complications were represented using the comprehensive complication index (CCI), poorer preoperative physical function scores were associated with higher CCI scores (B = -0.277, p = 0.014). Preoperative social function score (OR = 0.925, 95% CI 0.87 to 0.99; p = 0.019) was an independent predictor for 30-day readmission, while physical functioning score (OR = -0.620, 95% CI -1.073--0.167, p = 0.008) was inversely related to the length of hospitalization. The overall regressions for 1-month postoperative global QOL (R2: 0.546, F: 1.961, p = 0.023) and 30-day readmission (R2: 0.322, χ2: 13.129, p < 0.001) were statistically significant. Conclusions: Various QLQ-C30 domains were found to be predictive of postoperative outcomes, including complications, readmission, and length of hospitalization. Preoperative cognitive dysfunction and low AR were independent predictors of poorer postoperative global QOL. Future research should seek to examine the efficacy of targeting specific baseline QOL domains in improving clinical as well as patient-reported outcomes after CRC surgery.

BACKGROUND: Smaller prostates have been linked to unfavorable clinical characteristics and poor short-term outcomes following radical prostatectomy (RP). We examined the relation between prostate weight at RP and prostate cancer (PC) outcomes post-RP. METHODS: Men in the SEARCH cohort undergoing RP between 1988 and 2017 (N = 6242) were studied for PC-specific mortality (PCSM) as the primary outcome, and for biochemical recurrence (BCR), castration-resistant PC (CRPC) and metastasis as secondary outcomes. Hazard ratios (HR) and 95% confidence intervals (CI) were determined for associations between prostate weight and outcomes using Fine-Gray competing risk regression multivariable analyses. Sensitivity analyses were also carried out following exclusion of: (i) men with extreme prostate weights (<20 g and ≥100 g); and (ii) men with elevated prostate specific antigen (PSA) levels. RESULTS: Median values for age, pre-RP PSA and prostate weight were 63 years, 6.6 ng/ml, and 42.0 g, respectively. During a median follow-up of 7.9 years, 153 (3%) died from PC, 2103 (34%) had BCR, 203 (3%) developed CRPC, and 289 (5%) developed metastases. Prostate weight was not associated with PCSM in the main analyses (multivariable HR = 1.43; 95% CI: 0.87-2.34) or in sensitivity analyses. Prostate weight was inversely associated with BCR in the main analyses (multivariable HR = 0.70; 95%CI: 0.61-0.79) which was unchanged in sensitivity analyses. HRs for prostate weight and CRPC and metastasis were elevated but statistical significance was not attained. Similar results were observed in sensitivity analyses. CONCLUSIONS: Inconsistent results for prostate weight and short-term vs longer-term outcomes highlight the need to better understand the complex biology leading to prostate size and the relevance of prostate size as a predictor of PC outcomes.

BACKGROUND: Breast cancer (BrCa) outcomes vary by social environmental factors, but the role of built-environment factors is understudied. The authors investigated associations between environmental physical disorder-indicators of residential disrepair and disinvestment-and BrCa tumor prognostic factors (stage at diagnosis, tumor grade, triple-negative [negative for estrogen receptor, progesterone receptor, and HER2 receptor] BrCa) and survival within a large state cancer registry linkage. METHODS: Data on sociodemographic, tumor, and vital status were derived from adult women who had invasive BrCa diagnosed from 2008 to 2017 ascertained from the New Jersey State Cancer Registry. Physical disorder was assessed through virtual neighborhood audits of 23,276 locations across New Jersey, and a personalized measure for the residential address of each woman with BrCa was estimated using universal kriging. Continuous covariates were z scored (mean ± standard deviation [SD], 0 ± 1) to reduce collinearity. Logistic regression models of tumor factors and accelerated failure time models of survival time to BrCa-specific death were built to investigate associations with physical disorder adjusted for covariates (with follow-up through 2019). RESULTS: There were 3637 BrCa-specific deaths among 40,963 women with a median follow-up of 5.3 years. In adjusted models, a 1-SD increase in physical disorder was associated with higher odds of late-stage BrCa (odds ratio, 1.09; 95% confidence interval, 1.02-1.15). Physical disorder was not associated with tumor grade or triple-negative tumors. A 1-SD increase in physical disorder was associated with a 10.5% shorter survival time (95% confidence interval, 6.1%-14.6%) only among women who had early stage BrCa. CONCLUSIONS: Physical disorder is associated with worse tumor prognostic factors and survival among women who have BrCa diagnosed at an early stage.

PURPOSE: This study evaluated whether patients with de novo metastatic breast cancer (MBC) have superior outcomes compared to those with recurrent MBC in a contemporary treatment era and examined factors related to outcome differentials. METHODS: Using an institutional database, we examined patient and tumor characteristics, treatment response, and outcome among 232 patients with de novo and 612 patients with recurrent MBC diagnosed between 2011 and 2017. RESULTS: De novo MBC had 9-month (m) longer overall survival (OS) than recurrent MBC (36.4 vs 27.4 m, p < 0.001). Contributions to this difference included nearly twofold more HER2-positive (29.3% vs 15.2%) and significantly fewer triple-negative breast cancers (20.3% vs 32.4%, both p < 0.001) in de novo compared with recurrent MBC cohorts. Stratified by clinical subtype, progression-free survival (PFS) on first-line therapy was significantly longer in de novo MBC in all but the triple-negative subtype, 25.5 vs 11.6 m (p < 0.001) among 390 patients with hormone receptor-positive, HER2-negative, 11.4 vs 5.4 m (p = 0.002) among 142 patients with HER2-positive, and 4.0 vs 3.0 m (p = 0.121) among 162 with triple-negative MBC. In multivariable analysis, de novo status remained independently associated with improved OS (hazard ratio 0.63, 95% CI 0.49-0.80), regardless of subtype and other features. CONCLUSION: Patients with de novo MBC have better outcomes than those with recurrent MBC. Differences in clinical subtype and response to therapy in the metastatic setting contribute to, but do not fully explain, this difference. Longer PFS to first-line therapy in de novo MBC suggests biologic differences compared to recurrent MBC, which may be intrinsic or due to acquired resistance from treatment for prior localized breast cancer in recurrent disease.

PURPOSE: As survival with early-stage, hormone receptor (HR)-positive breast has improved, it is essential to understand the long-term risks of incident comorbidities with different adjuvant endocrine therapy (ET) options. METHODS: Women treated with tamoxifen and/or an aromatase inhibitor (AI) for stages 1-3, HR-positive/HER2-negative breast cancer from 2000 to 2016 in either of two healthcare systems in the San Francisco Bay Area were included. We considered the following comorbidities: cerebrovascular accidents, congestive heart failure, dementia, depression/anxiety, diabetes mellitus, hyperlipidemia, myocardial infarction, non-alcoholic steatohepatitis, osteoporosis/fracture, peripheral vascular disease, and venous thromboembolism. Cause-specific Cox proportional hazards models were fit to time-to-new-diagnosis for each comorbidity, accounting for death as a competing risk. Hazard ratios (HR) and 95% confidence intervals (CI) for tamoxifen versus AI were reported. RESULTS: Among 2,902 analyzed patients, the median age at diagnosis was 58.3 years; 67.6% were non-Hispanic white, 22.3% Asian, 7.5% Hispanic, and 1.7% non-Hispanic Black. Half (54.7%) used AIs only, 27.6% used tamoxifen only and 17.7% used both tamoxifen and AIs sequentially. Tamoxifen was associated with a lower risk of osteoporosis than AI (multivariable HR 0.45, 95% CI 0.32-0.62). No other incident comorbidity risk varied between users of tamoxifen versus AIs. CONCLUSION: In a diverse, multi-institutional, contemporary breast cancer cohort, the only incident comorbidity that differed between ET options was osteoporosis, a known side effect of AIs. These results may inform clinical decision-making about ET, and reassure patients who have bothersome symptoms on AIs that they are unlikely to develop worse comorbidities if they switch to tamoxifen.

We evaluated outcomes in 131 patients with cutaneous melanoma (median follow-up, 3.6 years) considered at high risk of recurrence after surgery alone treated with surgery and postoperative radiotherapy. Eligible patients had one or more of the following: recurrence after surgery, positive lymph nodes, extracapsular extension, incomplete regional node dissection, microscopically positive margins, gross residual disease, or in-transit metastases. 102 patients received hypofractionated radiotherapy and 29 had conventional fractionation. 10-year outcomes were: in-field local-regional control, 87%; local regional control, 72%; distant metastasis-free survival, 48%; cause-specific survival, 44%; and overall survival, 31%. Three patients experienced acute toxicities while 6 experienced late toxicities.

AIMS: Anal cancer is primarily treated using concurrent chemoradiotherapy (CRT), with conformal techniques such as intensity modulated radiotherapy (IMRT) and volumetric arc therapy (VMAT) now being the standard techniques utilised across the world. Despite this, there is still very limited consensus on prognostic factors for outcome following conformal CRT. This systematic review aims to evaluate the existing literature to identify prognostic factors for a variety of oncological outcomes in anal cancer, focusing on patients treated with curative intent using contemporary conformal radiotherapy techniques. MATERIALS AND METHODS: A literature search was conducted using Medline and Embase to identify studies reporting on prognostic factors for survival and cancer-related outcomes after conformal CRT for anal cancer. The prognostic factors which were identified as significant in univariable and multivariable analysis, along with their respective factor effects (where available) were extracted. Only factors reported as prognostic in more than one study were included in the final results. RESULTS: The results from 19 studies were analysed. In both univariable and multivariable analysis, N stage, T stage, and sex were found to be the most prevalent and reliable clinical prognostic factors for the majority of outcomes explored. Only a few biomarkers have been identified as prognostic by more than one study - pre-treatment biopsy HPV load, as well as the presence of leukocytosis, neutrophilia and anaemia at baseline measurement. The results also highlight the lack of studies with large cohorts exploring the prognostic significance of imaging factors. CONCLUSION: Establishing a set of prognostic and potentially predictive factors for anal cancer outcomes can guide the risk stratification of patients, aiding the design of future clinical trials. Such trials will in turn provide us with greater insight into how to effectively treat this disease using a more personalised approach.

PURPOSE: To report disease control and treatment-related side effects among adult patients with craniopharyngioma treated with radiotherapy. METHODS: We performed a single-institution review of adult patients (> 21 years old) with craniopharyngioma treated with radiotherapy either definitively or postoperatively for gross residual disease. We report disease control, survival, and radiotherapy-related side effects. RESULTS: A total of 49 adult patients with craniopharyngioma were included, 27 of whom were treated at initial presentation and 22 for recurrent disease following initial surgery and observation. Overall, 77% received radiotherapy postoperatively (either after primary surgery or surgery for recurrence). With a median clinical and radiographic follow-up of 4.2 (range, 0.4-21.6) years and 3.0 (range, 0-21.5) years, the 5- and 10-year local control rates were 100 and 94%, respectively. The 5- and 10-year overall survival rates were 80 and 66%, respectively. Eleven percent of patients experienced grade 2 vision deterioration and 18% suffered grade 2 endocrinopathies following radiotherapy. CONCLUSIONS: Radiotherapy provides excellent disease control with acceptable toxicity among adult patients with craniopharyngioma. These data support the use of fractionated radiotherapy in adult patients with recurrent or gross residual disease after surgery. For inoperable patients or those with moderate or high surgical risk to neurologic and/or vascular structures, we advocate for limited surgical resection and postoperative radiotherapy to balance optimal tumor control with tumor- and treatment-related morbidity.
