RESUMO
BACKGROUND: Nivolumab extends the overall survival (OS) of patients with advanced gastric cancer (AGC). Intramuscular adipose tissue (IMAT) is associated with the prognosis of patients with various cancers. We investigated the effect of IMAT on OS in patients with AGC treated with nivolumab. METHODS: We enrolled patients with AGC treated with nivolumab (n = 58, 67 years old, men/women 40/18). The subjects were classified into long-term or short-term survival groups according to the median value. The IMAT was evaluated using computed tomography scans at the umbilical level. The decision tree algorithm was employed to reveal the profile associated with prognosis. RESULTS: In decision tree analysis, immune-related adverse events (irAEs) were the first divergence variable, and prolonged survival was observed in 100% of patients with irAEs (profile 1). However, long survival was observed in 38% of patients with no irAEs. Among these patients, IMAT was identified as the second divergence variable, and long survival was observed in 63% of patients with high IMAT (profile 2). In patients with low IMAT, only 21% showed prolonged survival (profile 3). Median OS was 717 days (95% confidence interval [CI], 223 to not reached) in profile 1, 245 days (95% CI, 126 to 252) in profile 2, and 132 days (95% CI, 69 to 163) in profile 3. CONCLUSION: Immune-related adverse events and high IMAT were favorable factors for OS in patients with AGC treated with nivolumab. Thus, along with irAEs, skeletal muscle quality is important in managing patients with AGC treated with nivolumab.

Importance: For patients with RAS wild-type metastatic colorectal cancer, adding anti-epidermal growth factor receptor (anti-EGFR) or anti-vascular endothelial growth factor (anti-VEGF) monoclonal antibodies to first-line doublet chemotherapy is routine, but the optimal targeted therapy has not been defined. Objective: To evaluate the effect of adding panitumumab (an anti-EGFR monoclonal antibody) vs bevacizumab (an anti-VEGF monoclonal antibody) to standard first-line chemotherapy for treatment of RAS wild-type, left-sided, metastatic colorectal cancer. Design, Setting, and Participants: Randomized, open-label, phase 3 clinical trial at 197 sites in Japan in May 2015-January 2022 among 823 patients with chemotherapy-naive RAS wild-type, unresectable metastatic colorectal cancer (final follow-up, January 14, 2022). Interventions: Panitumumab (n = 411) or bevacizumab (n = 412) plus modified fluorouracil, l-leucovorin, and oxaliplatin (mFOLFOX6) every 14 days. Main Outcomes and Measures: The primary end point, overall survival, was tested first in participants with left-sided tumors, then in the overall population. Secondary end points were progression-free survival, response rate, duration of response, and curative (defined as R0 status) resection rate. Results: In the as-treated population (n = 802; median age, 66 years; 282 [35.2%] women), 604 (75.3%) had left-sided tumors. Median follow-up was 61 months. Median overall survival was 37.9 months with panitumumab vs 34.3 months with bevacizumab in participants with left-sided tumors (hazard ratio [HR] for death, 0.82; 95.798% CI, 0.68-0.99; P = .03) and 36.2 vs 31.3 months, respectively, in the overall population (HR, 0.84; 95% CI, 0.72-0.98; P = .03). Median progression-free survival for panitumumab vs bevacizumab was 13.1 vs 11.9 months, respectively, for those with left-sided tumors (HR, 1.00; 95% CI, 0.83-1.20) and 12.2 vs 11.4 months overall (HR, 1.05; 95% CI, 0.90-1.24). Response rates with panitumumab vs bevacizumab were 80.2% vs 68.6%, respectively, for left-sided tumors (difference, 11.2%; 95% CI, 4.4%-17.9%) and 74.9% vs 67.3% overall (difference, 7.7%; 95% CI, 1.5%-13.8%). Median duration of response with panitumumab vs bevacizumab was 13.1 vs 11.2 months for left-sided tumors (HR, 0.86; 95% CI, 0.70-1.10) and 11.9 vs 10.7 months overall (HR, 0.89; 95% CI, 0.74-1.06). Curative resection rates with panitumumab vs bevacizumab were 18.3% vs 11.6% for left-sided tumors; (difference, 6.6%; 95% CI, 1.0%-12.3%) and 16.5% vs 10.9% overall (difference, 5.6%; 95% CI, 1.0%-10.3%). Common treatment-emergent adverse events were acneiform rash (panitumumab: 74.8%; bevacizumab: 3.2%), peripheral sensory neuropathy (panitumumab: 70.8%; bevacizumab: 73.7%), and stomatitis (panitumumab: 61.6%; bevacizumab: 40.5%). Conclusions and Relevance: Among patients with RAS wild-type metastatic colorectal cancer, adding panitumumab, compared with bevacizumab, to standard first-line chemotherapy significantly improved overall survival in those with left-sided tumors and in the overall population.

BACKGROUND: Preoperative chemoradiotherapy (CRT), the current standard of care for locally advanced rectal cancer (LARC), is associated with many radiotherapy (RT)-related side effects. We aimed to evaluate whether S-1 and oxaliplatin (SOX) or folinic acid, 5-FU, and oxaliplatin (mFOLFOX6) can be as effective as neoadjuvant chemotherapy (NAC) regimens for LARC without RT. METHODS: Patients with untreated resectable LARC were randomly assigned to receive SOX or mFOLFOX6. The NAC protocol period was 3 months. The primary endpoint was 3-year disease-free survival (DFS), and the secondary endpoints included pathological effects, surgical completion rate, 3-year survival, and safety. RESULTS: From September 2013 to October 2015, 56 and 54 patients were enrolled in the SOX and mFOLFOX6 arms, respectively. The 3-year DFS rates were 69.4% (95% confidence interval [CI] 54.9-83.6) and 73.4% (95% CI 58.7-83.6) in the SOX and mFOLFOX6 arms, respectively; no significant differences were found between the arms (log-rank test; P = 0.5315, hazard ratio: 0.808, 95% CI 0.414-1.578). The 3-year survival rates were 92.3 and 91.8% in the SOX and mFOLFOX6 arms, respectively. The surgical completion rate was 98.1% overall, 100% in the SOX arm, and 96.0% in the mFOLFOX6 arm. The incidences of pathological response rates ≥grade 1b were 41.5 and 43.8% in the SOX and mFOLFOX6 arms, respectively. Both treatments were manageable and tolerable. CONCLUSION: We demonstrated the effectiveness and safety of SOX and mFOLFOX6, both of which may be new neoadjuvant treatment candidates in previously untreated LARC cases. TRIAL REGISTRATION: Date of enrolment of the first participant to the trial: 3rd Oct 2013; This study was registered in the UMIN clinical trials registry on 14th Aug, 2013.

The case involved a 44-year-old man who underwent intersphincteric resection and lateral lymph node dissection for rectal cancer. Pathological diagnosis revealed a well-differentiated adenocarcinoma comprising KRAS wild type, and pT2N0M0 (pathological Stage I). CapeOX (capecitabine plus oxaliplatin[L-OHP]), and bevacizumab therapy was initiated because of local recurrence. Although a partial response (PR) was observed, the therapy was terminated after 6 courses because of the development of hand-foot syndrome. FOLFIRI and cetuximab therapy was initiated after cancer recurrence was observed during a follow up. As the therapeutic efficiency is characterized by stability (stable disease: SD), and the tumor reduction effect observed was not sufficient, we performed an abdominoperineal resection to achieve local control. However, a left hydronephrosis occurred due to the pelvic recurrence, necessitating the emergency hospitalization of the patient. Because resistance to L-OHP was not confirmed, mFOLFOX6 and bevacizumab therapy was introduced in hopes of the effect of the former. As Grade 2 allergy (erythema) appeared immediately after the L-OHP was administered during the 3 courses, treatment was discontinued. We the reinitiated the treatment along with the desensitization therapy from the 4 courses. A total of 27 courses of mFOLFOX6 and bevacizumab therapy were administered until the state of disease progression (progression disease: PD) was determined. PR was defined as the best therapeutic efficiency. In some cases, discontinuation of treatment is necessary as observed in the present case due to the onset of L-OHP allergies, even if the overall effect of the treatment is expected to be good. Our case is essentialas it demonstrates the successfulness of desensitization therapy for L-OHP allergies.

OBJECTIVES: The purpose of this phase II study was to explore the efficacy and safety of an alternating regimen consisting of folinic acid, 5-fluorouracil (5-FU) and oxaliplatin (mFOLFOX6) plus bevacizumab, and folinic acid, 5-FU and irinotecan (FOLFIRI) plus bevacizumab as first-line treatment for patients with metastatic colorectal cancer. METHODS: Fifty-two patients with metastatic colorectal cancer received an alternating regimen consisting of four cycles of mFOLFOX6 plus bevacizumab followed by four cycles of FOLFIRI plus bevacizumab until disease progression. The primary endpoint was progression-free survival. RESULTS: The median age was 60 years (range 37-75 years). Median progression-free survival was 14.2 months (95 % confidence interval [CI] 10.6-16.3) and median overall survival was 28.4 months (95 % CI 22.6-39.1). The overall response rate was 60.0 % (95 % CI 45.2-73.6). Regarding toxicity, the commonest grade 3-4 hematological adverse events were neutropenia (34.6 %) and leukopenia (7.7 %), and the commonest grade 3-4 non-hematological adverse events were anorexia (13.5 %), fatigue (9.6 %), nausea (9.6 %), and vomiting (9.6 %). Bevacizumab-related grade 3-4 adverse events included hypertension (1.9 %) and thrombosis (1.9 %). CONCLUSIONS: An alternating regimen consisting of mFOLFOX6 plus bevacizumab and FOLFIRI plus bevacizumab is an effective and well-tolerated first-line chemotherapy combination for patients with metastatic colorectal cancer.

Farletuzumab is a humanized monoclonal antibody against folate receptor α (FRA). The purpose of the study is to assess safety and tolerability, the pharmacokinetic (PK) profile, and preliminary antitumor effect. Patients with ovarian cancer (OC) or FRA-expressing solid tumors who are resistant to standard treatments were eligible for the study. After single-dose administration for PK assessment, farletuzumab was administered by intravenous injection, repeating every week until disease progression. Dose-limiting toxicities (DLTs) were defined as grade 4 hematological and grade 3/4 nonhematological toxicities. Dose escalation was planned in 4 cohorts (50, 100, 200, and 400 mg/m(2)). Fourteen patients with OC and two patients with gastric cancer (GC) received farletuzumab infusion. Neither DLTs nor grade 3/4 toxicities were reported in all cohorts. Major adverse events, including grade 1/2 infusion related reaction (15 patients, 93.8%), headache (seven patients, 43.8%), and nausea and decreased appetite (five patients each, 31.3%), were observed and medically managed. AUC and Cmax increased dose-dependently and linear PK profiles were observed. No tumor shrinkage was recorded, but long-term disease stabilization for 25 and 20 months was observed in one patient with clear cell OC (100 mg/m(2)) and one patient with GC (400 mg/m(2)), respectively. No cumulative toxicity occurred in any patient. Farletuzumab was well tolerated in Japanese patients with a similar PK profile as compared with the US population. Long-term disease stabilization was observed in a subpopulation of clear cell OC and GC; both of them were resistant and progressive after standard chemotherapies (ClinicalTrials.gov Identifier: NCT01049061).

A 69-year-old man underwent right hemicolectomy for ascending colon cancer with liver metastases. Postoperative systemic chemotherapy did not reduce the metastases, and therefore, hepatic arterial infusion chemotherapy (HAI) was administered. The metastases decreased in size after 26 rounds of therapy, and the patient underwent resection. He is recurrence-free 63 months after the primary operation. A 57-year-old man underwent Hartmann's operation for sigmoid colon cancer with liver metastases. He underwent hepatic left lobe resection after metastases reduction by systemic chemotherapy. However, multiple liver metastases were detected 2 months later. Because the disease progressed despite the administration of systemic chemotherapy, HAI was utilized instead. The metastases decreased in size remarkably, and resection was performed. The patient is surviving 52 months after the primary operation while being continuously treated with HAI, resection, and systemic chemotherapy for re-recurrence. HAI is a potential alternative treatment for patients with colorectal liver metastases resistant to systemic chemotherapy.

Although an association exists between the timing of immune checkpoint inhibitor (ICI) administration and therapeutic efficacy in several types of cancer, to the best of our knowledge, no reports exist regarding this relationship in gastric cancer (GC). The present study aimed to evaluate the optimal timing of ICI (nivolumab) administration in patients with advanced GC. A total of 58 consecutive patients with advanced GC who received nivolumab monotherapy after ≥2 chemotherapy regimens were retrospectively evaluated. These patients were divided into two groups according to the median time of nivolumab administration: i) Early-timing and (ii) late-timing groups, and the efficacy was assessed in both groups. The early-timing group had significantly longer overall survival (OS) than the late-timing group [median OS 8.2 months; 95% confidence interval (CI), 4.2-12.9 vs. median OS 5.4 months; 95% CI, 3.6-6.1]. Moreover, patients in the early-timing group had significantly longer progression-free survival (PFS) than those in the late-timing group (median PFS 2.6 months; 95% CI, 1.3-3.9 months vs. median PFS 1.6 months; 95% CI, 0.9-2.1 months). Furthermore, univariate analysis showed that early timing, immune-related adverse events and nonsteroidal anti-inflammatory drug administration were associated with longer OS and PFS. Cutoff Finder analysis revealed that the optimal timing of nivolumab administration for achieving better outcomes was before 12:06 p.m. Nivolumab administration in the morning, especially before 12:06 p.m., had a better clinical impact on patients with advanced GC.
RESUMO
Purpose: Elastomeric infusion pumps are widely used in colorectal cancer chemotherapy. However, no studies to date have investigated patient preferences regarding different infusion pump types. Patients and Methods: Twenty patients with unresectable colorectal cancer undergoing chemotherapy were initially treated with a portable hard-shelled continuous infusion pump, followed by a soft-shelled continuous infusion pump. The respondents used a numerical rating scale (0-10) to rate their comfort when using each pump, their ease of carrying it, the pump size and shape, its weight, their ease of reading its memory, and their overall satisfaction with it. They were then asked to determine which pump they would ultimately prefer. Results: In terms of comfort, significantly higher user satisfaction was reported for the soft-shelled pump during the daytime and when going out (P < 0.001, P < 0.001, respectively). For pump portability, size, shape, and weight, the soft-shelled type also outperformed the hard-shelled one (P < 0.001, P=0.0011, P < 0.001, respectively). However, the hard-shelled pump scored significantly better in terms of ease of viewing memory (P < 0.001). Overall satisfaction was significantly higher for the soft-shelled pump than the hard-shelled type (P=0.0095). Finally, 13 patients (65%) indicated that they would prefer a soft-shelled pump for their next treatment, while only one patient (5%) preferred a hard-shelled alternative. A preference for soft-shelled pump was observed, particularly in female patients and those with a body mass index of < 22 kg/m2. Conclusion: The selection of portable elastomeric infusion pumps should consider the preferences of patients with colorectal cancer, as these devices have the potential to enhance their quality of life.
RESUMO
This study aimed to compare second-line treatment outcomes for patients with unresectable pancreatic cancer previously treated with gemcitabine plus nab-paclitaxel (GnP) therapy. We conducted an integrated analysis of two retrospective studies included 318 patients receiving nanoliposomal irinotecan + 5-fluorouracil/folinic acid (NFF) (n = 102), S-1 (n = 57), or FOLFIRINOX (n = 14) as second-line treatment. Median overall survival (OS) in the NFF group was 9.08 months, significantly better than S-1 (4.90 months, P = 0.002). FOLFIRINOX had a median OS of 4.77 months, not statistically different from NFF. Subgroup analyses of OS indicated NFF was generally superior, however, a statistical interaction was observed between the treatment regimen in serum Alb < 3.5 g/dL (P = 0.042) and serum CRP ≥ 0.3 mg/dL (P = 0.006). Median progression-free survival (PFS) was 2.93 months for NFF, significantly better than S-1 (2.53 months, P = 0.024), while FOLFIRINOX had a comparable PFS (3.04 months, P = 0.948). Multivariate analysis identified the serum CRP, serum CA19-9, duration of first-line GnP therapy, and use (yes/no) of S-1 for second-line treatment as independent predictors for OS. This study concludes that second-line NFF therapy demonstrated a more favorable OS compared to S-1 therapy, however, it is still important to consider the patient background characteristics while selecting the most appropriate treatment.

Certain genetic alterations and right-sided primary tumor location are associated with resistance to anti-epidermal growth factor (EGFR) treatment in metastatic colorectal cancer (mCRC). The phase 3 PARADIGM trial (n = 802) demonstrated longer overall survival with first-line anti-EGFR (panitumumab) versus antivascular endothelial growth factor (bevacizumab) plus modified FOLFOX6 in patients with RAS wild-type mCRC with left-sided primary tumors. This prespecified exploratory biomarker analysis of PARADIGM (n = 733) evaluated the association between circulating tumor DNA (ctDNA) gene alterations and efficacy outcomes, focusing on a broad panel of gene alterations associated with resistance to EGFR inhibition, including KRAS, NRAS, PTEN and extracellular domain EGFR mutations, HER2 and MET amplifications, and ALK, RET and NTRK1 fusions. Overall survival was prolonged with panitumumab plus modified FOLFOX6 versus bevacizumab plus modified FOLFOX6 in patients with ctDNA that lacked gene alterations in the panel (that is, negative hyperselected; median in the overall population: 40.7 versus 34.4 months; hazard ratio, 0.76; 95% confidence interval, 0.62-0.92) but was similar or inferior with panitumumab in patients with ctDNA that contained any gene alteration in the panel (19.2 versus 22.2 months; hazard ratio, 1.13; 95% confidence interval, 0.83-1.53), regardless of tumor sidedness. Negative hyperselection using ctDNA may guide optimal treatment selection in patients with mCRC. ClinicalTrials.gov registrations: NCT02394834 and NCT02394795 .

Nanoliposomal irinotecan with fluorouracil and folinic acid (NFF) is a standard regimen after gemcitabine-based therapy for patients with unresectable or recurrent pancreatic cancer. However, there are limited clinical data on its efficacy and safety in the real-world. We therefore initiated a retrospective and prospective observational study (NAPOLEON-2). The results of the retrospective part were reported herein. In this retrospective study, we evaluated 161 consecutive patients who received NFF as second-or-later-line regimen. The main endpoint was overall survival (OS), and the other endpoints were response rate, disease control rate, progression-free survival (PFS), dose intensity, and adverse events (AEs). The median age was 67 years (range, 38-85 years). The median OS and PFS were 8.1 and 3.4 months, respectively. The objective response and disease control rates were 5% and 52%, respectively. The median relative dose intensity was 81.6% for nanoliposomal irinotecan and 82.9% for fluorouracil. Grade 3 or 4 hematological and nonhematological AEs occurred in 47 and 42 patients, respectively. Common grade 3 or 4 AEs included neutropenia (24%), anorexia (12%), and leukocytopenia (12%). Subanalysis of patients treated with second-line and third-or-later-line demonstrated no statistical significant difference in OS (7.6 months vs. 9.1 months, respectively; hazard ratio, 0.92; 95% confidence interval, 0.64-1.35; p = 0.68). In conclusion, NFF has acceptable efficacy and safety profile even in real-world clinical settings. The prospective study is in progress to validate these findings.

BACKGROUND: Patients with cancer often receive chemotherapeutic agents concurrently with other medications to treat comorbidity. The practical effects of concomitant medications, especially polypharmacy, on adverse drug reactions related to irinotecan-based chemotherapy are not well documented. METHODS: Associations of adverse drug reactions related to irinotecan monotherapy or a combination of irinotecan, 5-fluorouracil, and L-leucovorin (FOLFIRI) with concomitant medicines used to treat comorbidity were retrospectively investigated in Japanese patients with cancer. RESULTS: Of the 172 patients, 118 received concomitant medications. Twenty-one patients had grade 4 neutropenia and/or grade 3 or 4 diarrhea. Univariate and multivariate analyses revealed that concomitant medications were significantly associated with irinotecan-related severe neutropenia and/or diarrhea (P = 0.023 and 0.044). Multiple concomitant medications were significantly related to severe irinotecan-related toxicity in patients given monotherapy or FOLFIRI (P = 0.01). The incidence of severe irinotecan-related toxicities increased in parallel with the number of concomitant medications. CONCLUSION: We found that multiple concomitant medicines were significantly associated with severe irinotecan-related toxicity, indicating that polypharmacy must be effectively managed to decrease the risk of adverse drug reactions in patients with cancer who received irinotecan-based chemotherapy.

Background Balloon pulmonary angioplasty (BPA) is a promising treatment modality for nonoperable chronic thromboembolic pulmonary hypertension (CTEPH). However, BPA for atypical CTEPH with concurrent chronic obstructive pulmonary disease (COPD) remains controversial owing to the risk of exacerbation of ventilation-perfusion mismatch. We aimed to evaluate the efficacy and safety of BPA for CTEPH with moderate or severe COPD. Methods and Results Data from 149 patients with CTEPH, who underwent BPA from March 2011 to June 2021, were retrospectively analyzed. Patients were divided based on COPD comorbidity: the COPD group (n=32, defined as forced expiratory volume in 1 second/forced vital capacity <70% and forced expiratory volume in 1 second <80% predicted) and the non-COPD group (n=101); patients with mild COPD (n=16) were excluded. Hemodynamic and respiratory parameters were compared between the groups. Hemodynamics improved similarly in both groups (reduction in pulmonary vascular resistance): -55.6±29.0% (COPD group) and -58.9±21.4% (non-COPD group); P=nonsignificant. Respiratory function and oxygenation improved in the COPD group (forced expiratory volume in 1 second/forced vital capacity [61.8±7.0% to 66.5±10.2%, P=0.02] and arterial oxygen partial pressure [60.9±10.6 mm Hg to 69.3±13.6 mm Hg, P<0.01]). Higher vital capacity (P=0.024) and higher diffusing capacity for lung carbon monoxide (P=0.028) at baseline were associated with greater improvement in oxygenation in the multivariable linear analysis. Lung injury per BPA session was 1.6% in the COPD group. Conclusions The efficacy and safety of BPA for nonoperable CTEPH in patients with comorbid COPD were similar to those in patients without COPD. Oxygenation and forced expiratory volume in 1 second/forced vital capacity improved in patients with COPD. BPA should be considered in patients with CTEPH with concurrent COPD.

Introduction: Expression of the NTRK gene is rare in solid tumors but is highly prevalent in salivary gland secretory carcinomas. Here, we report a case of a complete response to entrectinib in a patient with NTRK fusion gene-positive parotid carcinoma. Case description: The patient was a 44-year-old man who underwent total left parotidectomy and left cervical lymph node dissection for a left parotid tumor at 24 years of age. The histopathological diagnosis was mammary analog secretory carcinoma. Postoperatively, the patient received only radiation therapy. Sixteen years after the surgery, the patient became aware of a mass in the left parotid region. A close examination revealed local recurrence and multiple cervical lymph node metastases. S-1 monotherapy was started as chemotherapy but was discontinued 3 years later because of disease progression. As there was no standard treatment, a comprehensive genomic profiling test using a next-generation sequencer was performed, and the ETV6-NTRK3 fusion gene was identified. Entrectinib, an NTRK inhibitor, was immediately administered at a dose of 600 mg/day. The local recurrence rapidly shrank grossly from the beginning of treatment, and a complete response was observed 6 months later. However, creatinine levels exhibited an increase at week 68 of treatment; consequently, entrectinib dosage was lowered to 400 mg/day, leading to an immediate improvement in creatinine levels. Entrectinib was associated with additional side effects, including dysgeusia, fatigue, dizziness, and weight gain, all of which were also alleviated by the reduction in entrectinib dose. Thirty months after treatment initiation, the patient maintained a complete response and continued to receive entrectinib. Conclusion: The NTRK fusion gene should always be checked in the presence of salivary gland secretory carcinoma.
RESUMO
Introduction: Reports on the long-term quality of life (QOL) over 3 years after surgery in patients who have undergone surgery for rectal cancer are limited. Therefore, we aimed to evaluate the long-term QOL of patients who underwent high anterior resection (HAR), low anterior resection (LAR), internal sphincter resection (ISR), or abdominoperineal resection (APR) for rectal cancer. Methods: A questionnaire regarding QOL was sent to 360 patients with rectal cancer who underwent curative resection by HAR, LAR, ISR, or APR between January 2005 and December 2015. QOL was assessed using the short-form 36 (SF-36) and modified fecal incontinence QOL (mFIQL) questionnaire. QOL between surgical procedures was analyzed using a multivariate model adjusted for age, sex, and postoperative time. Results: A total of 144 patients responded with a median follow-up period of 94 months (range 38-233 months). According to surgical procedure, HAR was performed in 26 patients, LAR in 80 patients, ISR in 32 patients, and APR in 6 patients. Patients who underwent HAR had significantly better mFIQL scores than those who underwent LAR and ISR (p=0.013 and p=0004, respectively) and significantly better role/social component summary scores on the SF-36 subscales (p=0.007). No difference was observed in the mFIQL scores between patients who underwent ISR and those who underwent APR (p=0.8423). In addition, postoperative anastomotic leakage sutures did not influence the mFIQL and SF-36 scores after surgery. Conclusion: The QOL of patients who underwent anus-preserving surgery was best in the HAR group, with the QOL of other groups similar to the APR group. These results suggest that anus- preserving surgery is acceptable from a QOL standpoint. However, a colostomy may be a more satisfactory procedure in some patients.
RESUMO
Bevacizumab (BEV) requires an adequate withdrawal period to avoid BEV-related complications during major surgery. However, the safety of BEV administration immediately after surgical placement of the central venous (CV) port, a minor surgery, is still unclear. This study aimed to investigate whether BEV is safe when administered early after CV port placement. We retrospectively evaluated 184 patients with advanced colorectal cancer (CRC) treated with a BEV-containing regimen and divided them into two groups according to the interval between CV port implantation and chemotherapy initiation, with the early administration group being ≤7 days and late administration group being >7 days. Complications were then compared between the two groups. The early-administration group was significantly older and had a higher rate of colon cancer than the late-administration group. Overall, 24 (13%) patients developed CV port-related complications. Male sex was a risk factor for complications (odds ratio [OR], 3.154; 95% CI, 1.19-8.36). The two groups showed no significant difference in the frequency of complications (p = 0.84) or patient characteristics (after the inverse probability of treatment weighting, p = 0.537). In conclusion, the frequency of complications is not affected by the timing of BEV initiation after CV port implantation. Thus, early BEV administration after CV port placement is safe.
RESUMO
The occurrence of fulminant type 1 diabetes mellitus as an adverse event during cancer immunotherapy has been previously reported. However, little is known about the causal relationship between the coronavirus disease 2019 (COVID-19) vaccination and fulminant type 1 diabetes mellitus. A 60-year-old man with advanced gastric cancer, receiving S-1 + oxaliplatin and nivolumab therapy, followed by nab-paclitaxel + ramucirumab as a second-line treatment, with steroid supplementation for complications of hypopituitarism-induced hypoadrenocorticism, was administered a COVID-19 vaccine after three cycles of nab-paclitaxel + ramucirumab. Two days later, he developed severe malaise and anorexia, which required emergency admission to our hospital for suspected adrenal insufficiency. Despite increasing steroids, his general condition changed suddenly after 12 hours leading to his death. Histopathological analysis of autopsy samples revealed loss of the islets of Langerhans, indicating fulminant type 1 diabetes mellitus. We failed to recognize the onset of fulminant type 1 diabetes mellitus because its symptoms were similar to those of adrenal insufficiency. The number of reports on the onset of fulminant type 1 diabetes mellitus after COVID-19 vaccination has been increasing, and in this case, the onset occurred on the second day after COVID-19 vaccination, suggesting an association between vaccination and fulminant type 1 diabetes mellitus. Clinicians should be aware of the risk of fulminant type 1 diabetes mellitus, although rare, after COVID-19 vaccination.
