Project description:PurposeClinical prognostic criteria using preoperative factors were not developed for post-neoadjuvant therapy (NAT) surgery of pancreatic ductal adenocarcinoma (PDAC). We aimed to identify preoperative factors associated with overall survival (OS) in PDAC patients who underwent post-NAT curative-intent surgery and develop risk stratification criteria.Materials and methodsConsecutive PDAC patients who underwent post-NAT curative-intent surgeries between 2007 and 2020 were retrospectively analyzed. Demographic, laboratory, surgical, and histopathologic variables were collected. Baseline, preoperative, and interval changes of computed tomography (CT) findings proposed by the Society of Abdominal Radiology and the American Pancreatic Association were analyzed. Cox proportional hazard analysis was used to select preoperative variables associated with OS. We developed risk stratification criteria composed of the significant preoperative variables, i.e., post-NAT response criteria. We compared the discrimination performance of post-NAT response criteria with that of post-NAT pathological (yp) American Joint Cancer Committee TNM staging system.ResultsOne hundred forty-five PDAC patients were included. Stable or increased tumor size on CT (hazard ratio [HR], 2.58; 95% confidence interval [CI], 1.58 to 4.21; p < 0.001) and elevated preoperative carbohydrate antigen 19-9 (CA19-9) level (HR, 1.98; 95% CI, 1.11 to 3.55; p=0.021) were independent factors of OS. The OS of the patient groups stratified by post-NAT response criteria which combined changes in tumor size and CA19-9 showed significant difference (p < 0.001). Such stratification was comparable to ypTNM staging in discrimination performance (difference of C-index, 0.068; 95% CI, -0.012 to 0.142).Conclusion"Any degree of decrease in tumor size on CT" and CA19-9 normalization or staying normal were independent favorable factors of OS. The combination of the two factors discriminated OS comparably to ypTNM staging.

Project description:BackgroundAdrenal insufficiency is a life-threatening condition, and advanced gastric cancer is associated with very poor prognosis. Adrenalectomy and/or metastatic invasion of the adrenal glands can cause primary adrenal insufficiency, which in turn can present with symptoms mimicking advanced cancer.Case presentationHerein we report of a 68-year-old White male with a history of left adrenalectomy in conjunction with distal gastrectomy due to gastric adenocarcinoma. At the 2-year follow-up visit after cancer surgery, the patient presented with fatigue, unintentional weight loss, hyperkalemia, and a computed tomography scan with a right adrenal mass. Primary adrenal insufficiency caused by gastric cancer metastatic invasion of the remaining right adrenal gland was established and glucocorticoid therapy initiated. The patient received first line palliative chemotherapy with systemic disease control and subsequent stereotactic body radiotherapy to the right adrenal gland. More than 17 months after pathology-confirmed gastric cancer relapse, there is no clinical nor radiological evidence of active malignant disease and the patient is doing well on glucocorticoid replacement therapy.ConclusionsThis case does not only illustrate the importance of prompt and correct clinical management of adrenal insufficiency, but also that selected patients with advanced gastric cancer can gain from and achieve long-term survival using a multimodal treatment approach.

Project description:BackgroundThe optimal surgical indication after preoperative chemoradiotherapy (CRT) remains a subject of debate for patients with pancreatic ductal adenocarcinoma (PDAC) because early recurrence often occurs even after curative-intent resection. The present study aimed to identify perioperative risk factors of early recurrence for patients with PDAC who underwent curative-intent resection after preoperative CRT.MethodsTwo hundred three patients with PDAC who underwent curative-intent resection after preoperative CRT from February 2005 to December 2018 were retrospectively analyzed. The optimal threshold for differentiating between early and late recurrence was determined by the minimum p-value approach. Multivariate regression analysis was performed to identify predictive factors for early recurrence.ResultsIn 130 patients who developed recurrence after resection, 52 who had an initial recurrence within 12 months were defined as the early recurrence group, and the remaining 78 were defined as the late recurrence group. The incidence of hepatic recurrence was significantly higher in the early recurrence group than in the late recurrence group (39.7 vs. 15.4%). The early recurrence group had significantly lower 3-year rates of post-recurrence and overall survival than the late recurrence group (4.0 and 10.7% vs. 9.8 and 59.0%, respectively). Serum level of CA19-9 before surgery ≥56.8 U/ml was identified as an independent risk factor for early recurrence (OR:3.07, 95%CI:1.65-5.73, p<0.001) and associated with a significantly higher cumulative incidence rate of hepatic recurrence and lower rates of recurrence-free and overall survival.ConclusionSerum level of CA19-9 before surgery after preoperative CRT was a strong predictive factor for early recurrence.

Project description:BACKGROUND:Pancreatic metastasis is a rare cause for pancreas surgery and often a sign of advanced disease no chance of curative-intent treatment. However, surgery for metastasis might be a promising approach to improve patients' survival. The aim of this study was to analyze the surgical and oncological outcome after pancreatic resection of pancreatic metastasis. METHODS:This is a retrospective cohort analysis of a prospectively-managed database of patients undergoing pancreatic resection at the University of Freiburg Pancreatic Center from 2005 to 2017. RESULTS:In total, 29 of 1297 (2%) patients underwent pancreatic resection due to pancreatic metastasis. 20 (69%) patients showed metastasis of renal cell carcinoma (mRCC), followed by metastasis of melanoma (n?=?5, 17%), colon cancer (n?=?2, 7%), ovarian cancer (n?=?1, 3%) and neuroendocrine tumor of small intestine (n?=?1, 3%). Two (7%) patients died perioperatively. Median follow-up was 76.4 (range 21-132) months. 5-year and overall survival rates were 82% (mRCC 89% vs. non-mRCC 67%) and 70% (mRCC 78% vs. non-mRCC 57%), respectively. Patients with mRCC had shorter disease-free survival (14 vs. 22 months) than patients with other primary tumor entities. CONCLUSION:Despite malignant disease, overall survival of patients after metastasectomy for pancreatic metastasis is acceptable. Better survival appears to be associated with the primary tumor entity. Further research should focus on molecular markers to elucidate the mechanisms of pancreatic metastasis to choose the suitable therapeutic approach for the individual patient.

Project description:BackgroundPatients with bladder cancer may experience mental health distress. Mental health-care service (MHS) use can quantify the magnitude of the problem.MethodsThe Ontario Cancer Registry was used to identify all patients with bladder cancer treated with curative-intent cystectomy or radiotherapy in Ontario, Canada (2004-2013). Population-level databases were used to identify MHS use (visits to general practitioner, psychiatrist, emergency department, or hospitalization). Generalized estimating equations were used to compare rates of MHS use. Baseline, peritreatment, and posttreatment MHS use were defined as visits from 2 years to 3 months before, 3 months before to 3 months after, and from 3 months after to 2 years after start of treatment, respectively.ResultsFrom 2004 to 2013, 4296 patients underwent cystectomy (n = 3332) or curative-intent radiotherapy (n = 964). Compared with baseline, the rate of MHS use was higher in the peritreatment (adjusted rate ratio [aRR] = 1.64, 95% confidence interval [CI] = 1.48 to 1.82) and posttreatment periods (aRR = 1.45, 95% CI =1.30 to 1.63). By 2 years posttreatment, 24.6% (95% CI = 23.4% to 25.9%) of all patients had MHS use. Patients with baseline MHS use had substantially higher MHS use in the peritreatment (aRR = 5.77, 95% CI = 4.86 to 6.86) and posttreatment periods (aRR = 4.58, 95% CI = 3.78 to 5.55). Female patients had higher use MHS use overall, but males had a higher incremental increase in the posttreatment period compared with baseline (2-sided Pinteraction = .02). Male patients had a statistically significant increase in MHS use following surgery or radiotherapy, whereas female patients only had an increase following surgery.ConclusionsMHS use is common among patients undergoing treatment for bladder cancer, particularly in the peritreatment period. Screening for mental health concerns in this population is warranted.

Project description:The introduction of immunotherapy has fundamentally transformed the treatment landscape in cancer, providing long-term survival benefit for patients with advanced disease across multiple tumor types, including non-small cell lung cancer (NSCLC). In the placebo-controlled phase 3 PACIFIC trial, the PD-L1 inhibitor durvalumab demonstrated significant improvements in progression-free survival and overall survival in patients with unresectable, stage III NSCLC who had not progressed after platinum-based chemoradiotherapy (CRT). These findings have led to the widespread acceptance of the 'PACIFIC regimen' (durvalumab after CRT) as the standard of care in this setting. Moreover, the PACIFIC trial is the first study to demonstrate a proven survival advantage with an immunotherapy in a curative-intent setting, thereby providing a strong rationale for further investigation of durvalumab in early-stage cancers. Herein, we describe the extensive clinical development program for durvalumab across multiple tumor types in curative-intent settings, outlining the scientific rationale(s) for its use and highlighting the innovative research (e.g., personalized cancer monitoring) advanced by these trials.

Project description:PurposeLung cancer treatment can lead to negative health consequences. We analyzed the effects of curative-intent lung cancer treatment on functional exercise capacity (EC) and patient-reported outcomes (PROs).MethodsWe performed a prospective, observational cohort study of consecutive patients with stage I-IIIA lung cancer undergoing curative-intent therapy and assessed functional EC (primary outcome, six-minute walk distance (6MWD)), cancer-specific quality of life (QoL) (secondary outcome, European Organization for Research and Treatment of Cancer QoL Questionnaire Core 30 (EORTC-QLQ-C30) summary score), and exploratory outcomes including dyspnea (University of California San Diego Shortness of Breath Questionnaire (UCSD SOBQ)) and fatigue Brief Fatigue Inventory (BFI)) symptoms before and at 1 to 3 months post-treatment. We analyzed the time effect of treatment on outcomes using multivariable generalized estimating equations.ResultsIn 35 enrolled participants, treatment was associated with a clinically meaningful and borderline-significant decline in functional EC ((mean change, 95% CI) 6MWD = - 25.4 m (- 55.3, + 4.47), p = 0.10), clinically meaningful and statistically significant higher dyspnea (UCSD SOBQ = + 13.1 (+ 5.7, + 20.6), p = 0.001) and fatigue (BFI = + 10.0 (+ 2.9, + 17.0), p = 0.006), but no clinically meaningful or statistically significant change in cancer-specific QoL (EORTC-QLQ-C30 summary score = - 3.4 (- 9.8, + 3.0), p = 0.30).ConclusionsAmong the first prospective analysis of the effect of curative-intent lung cancer treatment on functional EC and PROs, we observed worsening dyspnea and fatigue, and possibly a decline in functional EC but not cancer-specific QoL at 1 to 3 months post-treatment. Interventions to reduce treatment-related morbidities and improve lung cancer survivorship may need to focus on reducing dyspnea, fatigue, and/or improving functional EC.

Project description:BackgroundThe diagnosis of breast cancer and its subsequent treatment has significant impact on the woman's physical functioning, mental health and her well-being, and thereby causes substantial disruption to quality of life (QOL). Factors like patient education, spousal support and employment status, financial stability etc., have been found to influence QOL in the breast cancer patient. The present study attempts to identify the determinants of QOL in a cohort of Indian breast cancer patients.Patients and methodsFunctional Assessment of Cancer Therapy-Breast (FACT-B) Version 4 Malayalam was used to assess quality of life in 502 breast cancer patients undergoing treatment with curative intent. The data on social, demographic, disease, treatment, and follow-up were collected from case records. Data was analysed using Analysis of Variance (ANOVA) and multinomial logistic regression.ResultsThe mean age of the patients was 47.7 years with 44.6% of the women being pre-menopausal. The FACT-B mean score was 90.6 (Standard Deviation [SD] = 18.4). The mean scores of the subscales were - Physical well-being 19.6 (SD = 4.7), Social well-being 19.9 (SD = 5.3), Emotional well-being 14 (SD = 4.9), Functional well-being 13.0 (SD = 5.7), and the Breast subscale 23.8 (SD = 4.4). Younger women (< 45 years), women having unmarried children, nodal and/or metastatic disease, and those currently undergoing active treatment showed significantly poorer QOL scores in the univariate analysis. However multivariate analysis indicated that the religion, stage, pain, spouse education, nodal status, and distance travelled to reach the treatment centre as indicative of patient QOL.ConclusionQOL derangements are common in breast cancer patients necessitating the provisions for patient access to psychosocial services. However, because of the huge patient load, a screening process to identify those meriting intervention over the general population would be a viable solution.

Project description:BackgroundPrognostic implications of peritoneal washing cytology (CY) in patients with localized pancreatic ductal adenocarcinoma (PDAC) undergoing surgical resection following preoperative chemoradiotherapy (CRT) remain unclear. This study aimed to elucidate the prognostic significance and predictors of a positive CY status (CY+) after preoperative CRT.MethodsClinical data from 141 patients with localized PDAC who underwent curative-intent resection after preoperative CRT were retrospectively analyzed to examine the association between CY+ and clinicopathological factors and survival.ResultsCY+ was observed in six patients (4.3%). The CY+ group exhibited significantly higher preoperative serum levels of CA19-9 and a substantially greater incidence of tumor location in the pancreatic body or tail, along with pathological invasion to the anterior pancreatic capsule, than the CY- group. The CY+ group had a significantly higher incidence of peritoneal recurrence compared with the CY- group (83.3% vs. 18.5%, p = 0.002). Overall survival (OS) and recurrence-free survival (RFS) after surgery were significantly shorter in the CY+ group than in the CY- group (CY+ vs. CY-: 18.3 vs. 46.2 months, p = 0.001, and 8.9 vs. 17.7 months, p = 0.009, respectively). Multivariate analyses identified CY+ as an independent prognostic factor for worse OS (hazard ratio 5.00, 95% confidence interval 1.03-12.31) and RFS (hazard ratio 2.58, 95% confidence interval 1.04-6.43). Local invasion grade on imaging before CRT, limited histological response to CRT, and absence of adjuvant chemotherapy were independent predictors of worse OS and RFS.ConclusionDespite the relatively low incidence of CY+ after preoperative CRT, it emerged as an independent prognostic factor in patients with localized PDAC undergoing curative-intent resection following preoperative CRT.

Project description:ImportanceDespite standard chemoradiotherapy (CRT), most women with lymph node (LN)-positive cervical cancer experience disease recurrence. Immunotherapy is being investigated in the up-front treatment setting.ObjectivesTo assess the safety of sequential immunotherapy after CRT and to investigate human papillomavirus (HPV) genotype and HLA allele status on survival and programmed cell death 1 (PD-1) expression before and after CRT and sequential immunotherapy.Design, setting, and participantsThis prospective phase 1 trial conducted in 29 Gynecology Oncology Cooperative Group member institutions enrolled participants from December 18, 2012, to August 31, 2016, with a 14.8-month median follow-up and translational end points. Thirty-four women with International Federation of Gynecology and Obstetrics stage IB2 to IVA cervical cancer with positive pelvic LNs, para-aortic LNs, or both were enrolled; 13 did not receive ipilimumab and were excluded from the analysis. Data were analyzed from January 21 to April 4, 2018.InterventionsTreatment consisted of 6 weekly doses of cisplatin, 40 mg/m2, concurrent with radiotherapy. After completion of chemotherapy, sequential ipilimumab was given every 21 days for 4 doses. Two dosage levels of ipilimumab, 3 mg/kg and 10 mg/kg, were studied to identify the maximum tolerated dose.Main outcomes and measuresThe primary end point was safety, and the secondary end points were overall survival and progression-free survival. Exploratory end points included HPV genotype, HLA allele status, and PD-1 expression measured in peripheral blood.ResultsThe median age of the 32 participants included in the intent-to-treat analysis was 50 (range, 26-61) years, and 22 patients (69%) were white. Of the 21 patients who received ipilimumab, all had positive pelvic LN, and 6 (29%) had positive para-aortic LNs. All patients completed CRT, and of the 21 patients who received at least 2 cycles of ipilimumab, 18 (86%) completed 4 cycles of ipilimumab, and 3 (14%) completed 2 cycles. The maximum tolerated dose was 10 mg/kg. Two of the 21 patients (9.5%) who received ipilimumab had self-limiting grade 3 toxic effects (lipase increase; dermatitis). The 12-month overall survival was 90%, and progression-free survival was 81%. Human papillomavirus genotype and HLA subtype were not associated with progression-free survival or overall survival. T cells expressing PD-1 increased after CRT, and levels were sustained with ipilimumab.Conclusions and relevanceThis study's findings suggest that the use of immunotherapy after CRT for curative-intent treatment of patients with cervical cancer is tolerable and effective. The results indicated that PD-1 was upregulated after CRT and sustained with sequential ipilimumab therapy. These immune findings may help guide future therapies to harness the activated T-cell phenotype in patients with node-positive cervical cancer.
