Background: Colorectal cancer (CRC) is one of the few cancers for which screening has been associated with better survival and morbidity, but screening uptake has been underexplored in spouses of existing patients with CRC. The objective of this study was to evaluate whether a brief, structured behavioral intervention delivered to spouses of patients with CRC in a colorectal clinical setting could increase fecal immunochemical test (FIT) uptake within 3 months of the study period.

Methods: This study was designed as a block randomized, unblinded, parallel trial conducted in the colorectal outpatient clinics of 2 public tertiary hospitals in Singapore from December 2017 to February 2023. The intervention group received a structured informational pamphlet on CRC screening by the Singapore Ministry of Health and a printed guide with instructions on how to properly use a FIT kit.

Results: No significant differences in baseline characteristics were observed between the 2 groups. There was a statistically significant difference (P<.001) in FIT screening uptake between spouses in each group, with 86.2% (n=25) in the intervention group and 38.7% (n=12) in the control group.

Conclusions: Our study demonstrated that a brief, structured behavioral intervention offered to spouses accompanying patients with CRC while they wait for the clinic appointment is useful in increasing FIT screening uptake rates. Colorectal clinics can consider setting aside 10 to 15 minutes to educate accompanying spouses in the future as a complementary avenue to holistically promote CRC prevention, subjected to the resources available in each clinic.

Clinicaltrials: gov identifier: NCT04544852.

Background: Palliative systemic treatment is currently standard of care for metastatic gastric cancer. However, patients with peritoneal metastases of gastric origin are often underrepresented in clinical studies due to unmeasurable radiologic disease. This study describes the systemic treatment strategies and outcomes in patients with peritoneal metastases in a nationwide real-world setting.

Methods: Patients with gastric adenocarcinoma and synchronous peritoneal metastases (with or without other metastases) diagnosed in the Netherlands between 2015 and 2020 were identified from the nationwide Netherlands Cancer Registry. Median overall survival (OS) and time-to-treatment failure were determined and multivariable Cox regression analyses were used to compare treatment groups, corrected for relevant tumor and patient characteristics.

Results: In total, 1,972 patients were included, of whom 842 (43%) were treated with palliative systemic therapy. The majority received capecitabine + oxaliplatin (CAPOX; 44%), followed by fluorouracil/leucovorin/oxaliplatin (FOLFOX; 19%), and epirubicin + capecitabine + oxaliplatin (EOX; 8%). Of the 99 (45%) patients who received second-line systemic treatment, ramucirumab + paclitaxel were administered most frequently (63%). After adjustment for sex, age, comorbidities, performance status, tumor location, Lauren classification, and the presence of metastases outside of the peritoneum, patients treated with a triplet containing docetaxel and those treated with a regimen containing trastuzumab had a significantly longer OS compared with patients treated with a doublet containing a fluoropyrimidine derivate + oxaliplatin (hazard ratio [HR], 0.69; 95% CI, 0.52-0.91, and HR, 0.68; 95% CI, 0.51-0.91, respectively). Monotherapy was associated with a shorter OS (HR, 2.08, 95% CI, 1.53-2.83).

Conclusions: There is substantial heterogeneity in systemic treatment choices in patients with gastric cancer and peritoneal metastases in the Netherlands. In this study, patients treated with triplets containing docetaxel and with trastuzumab-containing regimens survived longer than patients who received doublet therapy. Despite this, median OS for all treatment groups remained below one year.

Background: Malignant phyllodes tumors (MPTs) are rare breast tumors with high risks of local recurrence and distant metastasis. Surgical intervention is the primary treatment, but the effectiveness of adjuvant therapies is uncertain. This study was designed to analyze the prognostic risk factors associated with MPTs and evaluate the efficacy of postoperative adjuvant chemotherapy.

Patients and methods: Patients who were first diagnosed with MPT without distant metastasis and received R0 resection surgery between 1999 and 2023 were included in the present study and stratified into 2 groups: chemotherapy and nonchemotherapy groups. Propensity score matching (PSM) was used to balance baseline characteristics between groups. Kaplan-Meier curves were used to estimate local recurrence-free survival (LRFS) and overall survival (OS). Cox proportional hazards analyses (univariate and multivariate) were conducted to identify prognostic risk factors.

Results: We conducted a study involving 145 patients, 31 of whom underwent a total of 12 different chemotherapy regimens following initial surgical resection. Most patients received chemotherapy regimens primarily consisting of anthracyclines, including anthracycline + ifosfamide (AI) or anthracycline + cyclophosphamide/docetaxel (AC-T) regimens. After a median follow-up of 54.5 months, 37 (25.5%) patients experienced local recurrence and 24 (16.6%) experienced distant metastasis. No significant difference was detected in the rates of local recurrence or distant metastasis between the 2 groups. Axillary lymph node positivity was the only risk factor for LRFS, whereas older age, larger tumors, axillary lymph node positivity, local recurrence, and distant metastasis were significantly associated with worse OS. Chemotherapy did not emerge as a protective factor for LRFS (P=.501) or OS (P=.854). After PSM, patients in the chemotherapy group did not exhibit better 5-year LRFS (P=.934) or 5-year OS (P=.328).

Conclusions: According to our retrospective evaluation, postoperative adjuvant chemotherapy was not associated with improved survival in patients with MPTs without distant metastasis.

Background: Recurrence score (RS) based on a 21-gene genomic assay is frequently used to estimate risk of distant recurrence for choice of adjuvant chemotherapy in breast cancer. It remains unclear whether RS is an independent prognostic factor for breast cancer-specific survival (BCSS) and overall survival (OS) in the TAILORx trial population.

Methods: We evaluated the association of RS with BCSS and OS plus recurrence-free interval (RFI) and invasive disease-free survival (DFS) using multivariable Cox proportional hazards regression analysis, adjusting for clinicopathologic measures, in 8,916 patients with hormone receptor-positive, HER2-negative, node-negative breast cancer. Likelihood ratio (LR) test was used to assess the relative amount of prognostic information provided by RS to BCSS, OS, RFI, and DFS, comparatively.

Results: Event rates for BCSS, OS, RFI, and DFS were 1.7%, 5.2%, 5.6%, and 12.6%, respectively, by up to 11.6 years of follow-up. Compared with low-range RS (0-10), patients with midrange (11-25) and high-range (26-100) RS had inferior BCSS (adjusted hazard ratio [aHR], 5.12 [95% CI, 2.09-16.92] and 8.03 [95% CI, 2.91-28.47], respectively) and RFI (aHR, 1.68 [95% CI, 1.23-2.36] and 3.05 [95% CI, 2.02-4.67], respectively), independent of clinicopathologic factors. High-range score was associated with an increased risk of DFS (aHR, 1.56 [95% CI, 1.20-2.04]) but not significantly associated with OS (aHR, 1.44 [95% CI, 0.95-2.18]). Midrange score was associated with neither DFS (aHR, 1.15 [95% CI, 0.96-1.38]) nor OS (HR 1.14 [95% CI, 0.87-1.52]). LR-χ2 values were 83.0 and 65.1 for RFI and BCSS, respectively, and 17.5 and 33.6 for OS and DFS, respectively (P<.0001).

Conclusions: RS is an independent measure for BCSS and recurrence prognoses relative to OS in early-stage breast cancer. It carries more prognostic information for breast cancer-specific outcomes.

Background: The overall landscape of health-related quality of life (HRQoL) has not been thoroughly investigated in adolescents and young adults (AYAs) with cancer. Data are also lacking on how well HRQoL at the time of cancer diagnosis can prognosticate long-term survival in AYA survivors.

Patients and methods: We included 3,497 survivors of AYA cancer (age 15-39 years at diagnosis) who completed the Short-Form 12 Health Survey (SF-12) HRQoL questionnaire at diagnosis. Physical component summary (PCS) and mental component summary (MCS) scores were generated, with scores <50 representing poor HRQoL. Differences in HRQoL by patient characteristics and tumor type were investigated using violin plots and t tests/analysis of variance. The effect of HRQoL on overall survival was assessed using Kaplan-Meier plots and Cox proportional hazards models.

Results: Overall mean PCS and MCS scores in this racially/ethnically diverse cohort (64% White, 19% Hispanic, 10% Black, and 7% other race/ethnicity) were 43.6 and 46.7, respectively. Women with breast cancer reported the most favorable PCS (50.8), and those with cervical cancer reported the lowest MCS (42.8). Age at diagnosis was associated positively with PCS (P<.001) and inversely with MCS (P<.001). Females had higher PCS yet lower MCS than males (both P<.001). Marginalized racial and ethnic populations reported lower PCS than White patients (P<.001). Physical and mental HRQoL were prognostic and associated with increased risk of poor survival (hazard ratio, 1.95; 95% CI, 1.72-2.21 for physical HRQoL, and 1.26; 95% CI, 1.13-1.40 for mental HRQoL).

Conclusions: Physical and mental HRQoL at diagnosis vary across patient characteristics in AYA cancer survivors. Poor HRQoL at diagnosis may be a prognosticator of diminished overall survival among AYA cancer survivors.

Background: Chemotherapy for various stages of gastroesophageal cancer (GEC) is often neurotoxic. Chemotherapy-induced peripheral neuropathy (CIPN) impairs health-related quality of life (HRQoL). This study investigates the incidence and severity of CIPN and its association with HRQoL in patients with GEC.

Patients and methods: Patients who received chemoradiotherapy or chemotherapy for GEC were identified from the Netherlands Cancer Registry. Patient-reported data (measured using the EORTC QLQ-CIPN20 and EORTC QLQ-C30) were collected through the Prospective Observational Cohort Study of Esophageal-Gastric Cancer Patients (POCOP) at baseline and at 3, 6, 9, 12, 18, and 24 months after treatment initiation. Linear mixed effects models were constructed to assess CIPN and the correlation between CIPN and HRQoL was analyzed using Spearman's correlation.

Results: A total of 2,135 patients were included (chemoradiotherapy: 1,593; chemotherapy with curative intent: 295; palliative chemotherapy: 247). In all 3 treatment groups, CIPN significantly increased during treatment (adjusted mean score of CIPN at 6 months: chemoradiotherapy, 8.3 [baseline: 5.5]; chemotherapy with curative intent, 16.0 [baseline: 5.6]; palliative therapy, 25.4 [baseline: 10.7]). For chemoradiotherapy, the adjusted mean score continued to increase after treatment (24 months: 11.2). For chemotherapy with curative intent and palliative therapy, the adjusted mean score of CIPN decreased after treatment but did not return to baseline values. CIPN was negatively correlated with HRQoL in all treatment groups, although significance and strength of the correlation differed over time.

Conclusions: Because of the poor prognosis of GEC, it is essential to consider side effects of (neurotoxic) treatment. The high prevalence and association with HRQoL indicate the need for early recognition of CIPN.
