RESUMO

BACKGROUND: Nivolumab has been approved for treating ≥ 10 cancer types. However, there is limited information on the incidence of rare, but potentially serious, treatment-related adverse events (TRAEs), as well as notable TRAEs in patients with certain medical disorders or older patients in Japan. METHODS: We performed pooled analyses of data from published post-marketing surveillance in Japan of nivolumab monotherapy for patients with malignant melanoma, non-small cell lung cancer, renal cell carcinoma, head and neck cancer, and gastric cancer to determine the frequencies of 20 categories of TRAEs of special interest overall and in patient groups with higher perceived safety risks (history of autoimmune disease, interstitial lung disease, tuberculosis, or hepatitis B/C; patients vaccinated during nivolumab treatment; and older patients [≥ 75 years]). RESULTS: The overall population comprised 7421 patients treated with nivolumab. TRAEs were reported in 49.1% of patients, with grade ≥ 3 TRAEs in 16.7%. Endocrine disorders (14.4%), hepatobiliary disorders (10.9%), and interstitial lung disease (7.0%) were the three most common categories (any grade). The incidences of rare TRAEs with high risk of becoming serious, which occurred in < 1% of patients, were consistent with those in previous reports. The frequencies of TRAEs were not markedly increased in the specified patient groups relative to the overall population. CONCLUSION: To our knowledge, this is the largest study examining the safety of nivolumab-treated patients in real-world clinical practice including rare but potentially serious TRAEs. We found no new signals in the safety of nivolumab among the patient groups relative to the overall population, and no additional safety measures are required in these groups. Trial registration UMIN000048892 (overall analysis), JapicCTI-163272 (melanoma), Japic-163271 (non-small cell lung cancer), JapicCTI-184071 (head and neck cancer), JapicCTI-184070 (gastric cancer), and JapicCTI-184069 (renal cell cancer).

RESUMO

Background: Central venous catheters (CVCs) are sometimes superior to peripheral vascular access for chemotherapy. Central line-associated bloodstream infections (CLABSIs) are an important complication of CVCs in chemotherapy. Methods: A retrospective, observational study was conducted to investigate patients with implanted venous access ports (PORTs) from July 2010 to June 2021 in a teaching hospital. General conditions of the PORTs, backgrounds, and characteristics of patients were compared between CLABSI cases and uninfected cases to identify predictors of CLABSI. Results: A total of 566 patients with PORTs who underwent chemotherapy were enrolled in this study, with CLABSI identified in 41 patients, for a total of 436,597 catheter-days. The median duration of PORT use was 26 vs. 494 days (P<0.001) in the CLABSI and uninfected groups, respectively. There were no significant differences in tumor classification, staging, white blood cell (WBC) count, neutrophil proportion, lymphocyte proportion, albumin, C-reactive protein (CRP), and performance status between the CLABSI and uninfected groups. Multivariable analysis showed that antibiotic usage within the previous week, total protein (TP), and immediate PORT use were independently associated with CLABSI, and their odds ratios (ORs) were 4.89 [95% confidence interval (CI): 1.67, 14.35], 1.95 (95% CI: 1.14, 3.53), and 3.13 (95% CI: 1.18, 8.30), respectively. The area under the curve (AUC) of the receiver-operating characteristic curve for TP was 0.63, and the cutoff value was 5.9 g/dL. Conclusions: PORT implantation should be avoided in patients who had antibiotic treatment episodes within 1 week, especially for those with low serum TP levels.

RESUMO

Nivolumab, a monoclonal antibody against human programmed death 1, was approved for the treatment of melanoma in July 2014 in Japan. Because the Japanese phase II studies (ONO-4538-02, ONO-4538-08) enrolled small numbers of melanoma patients, post-marketing surveillance (PMS; JapicCTI-163 272) was conducted to collect safety data in a larger patient population. We report data for melanoma patients who received nivolumab between July 4, 2014 and February 28, 2017. Data collected included baseline characteristics, laboratory tests, treatment-related adverse events (TRAE), and overall survival (OS). Of 2069 enrolled patients, 2008 patients were included in the safety analysis population. There were 1030 (51.3%) males, the median age was 69 years, and 269 patients (13.4%) had a performance status of ≥2. The primary tumor sites were cutaneous (34.4%), mucosal (34.2%), acral lentiginous (18.6%), others (6.8%), and unknown (6.3%). TRAE occurred in 62.1% of patients, the most common being hypothyroidism (14.0%), increased aspartate aminotransferase (8.5%), and increased alanine aminotransferase (6.9%). TRAE of special interest in ≥5% of patients were thyroid dysfunction (24.9%), hepatic dysfunction (20.6%), infusion reactions (11.4%), colitis/severe diarrhea (6.3%), and interstitial lung disease (ILD; 5.0%). Several types of TRAE of special interest, which included myasthenia gravis/myocarditis/myositis/rhabdomyolysis (0.9%), venous thromboembolism (0.2%), immune thrombocytopenic purpura (0.1%), and encephalitis (0.0%), were observed in this PMS. Although these TRAE were not reported in previous studies (ONO-4538-02, ONO-4538-08, CheckMate 066, and CheckMate 037), they have been listed in the current Risk Management Plan. History of ILD and male sex were risk factors for ILD in a multivariable analysis. Age <75 years was a risk factor for hepatic dysfunction. At 12 months, median OS was not reached. In conclusion, these results suggested that there was no concern requiring additional precautions for the safety of nivolumab in Japanese patients with melanoma other than the safety information in the Risk Management Plan.

RESUMO

This case was an infant with critical pulmonary stenosis at birth. A temporary one and a half ventricular repair was performed to increase right ventricular end-diastolic volume and the size of the tricuspid valve annulus before biventricular repair conversion. The one and a half ventricular repair was performed using a unidirectional bicaval Glenn anastomosis. The right ventricular end-diastolic volume at 3 years was 73.2% of normal value but with a 64/36 right/left lung perfusion ratio. An anatomic biventricular correction included removal of the bicaval Glenn shunt and reconstruction of the continuity between the right and main pulmonary arteries. The one and a half ventricular repair made the reconstruction feasible.

RESUMO

BACKGROUND: Malignancy-related ascites (MRA) is one of the symptoms causing discomfort in advanced cancer patients. Cell-free and concentrated ascites reinfusion therapy (CART) is one of the palliative treatments widely conducted in Japan only. METHODS: A systematic review following a meta-analysis of CART was performed. The efficiency and adverse events were evaluated. RESULTS: A total of 2567 patients and 6013 procedures of CART were identified in this study. The mean volume of MRA collected was 4.29 (95% confidence interval (CI) 3.47-5.11) L, and the volume reinfused after concentrating was 0.49 (95% CI 0.39-0.60) L. A total of 86.1 (95% CI 77.1-95.2) g protein and 42.9 (95% CI 36.0-50.0) g albumin was reinfused. The mean time to the next paracentesis was 20.7 (95% CI 15.6-25.8) days. The body weight was reduced by 3.38 (95% CI 1.90-4.86; p < 0.01) kg, and abdominal circumference was reduced by 7.86 (95% CI 6.58-9.14; p < 0.001) cm. Serum albumin increased an average of 0.14 (95% CI -0.01-0.28; p = 0.07) mg/dL the day after CART. Abdominal distension, dyspnea, and fatigue were alleviated by 6.0 (95% CI 5.59-6.51), 2.66 (95% CI 2.05-3.28), and 2.64 (95% CI 1.86-3.42) points using a numerical rating scale system ranging from 0 to 10. Overall, 17% (95% CI 0.03-0.31%) of patients had improved performance status after CART. Significant body temperature elevation was observed, at an average of 0.4 °C (95% CI 0.18-0.62 °C). CONCLUSIONS: CART might be a safe and effective palliative therapy in MRA and further clinical trials are necessary.

RESUMO

Postmarketing surveillance of Japanese patients with unresectable, previously treated, advanced or recurrent non-small-cell lung cancer treated with nivolumab was undertaken during the conditional approval period. The study aim was to evaluate the occurrence of treatment-related adverse events of nivolumab in the real world. Patients were registered between December 2015 and March 2016 at 536 sites. Nivolumab was given intravenously (3 mg/kg every 2 weeks); the observation period was 12 months after the first dose of nivolumab. Patients were evaluated for safety (n = 3601; 18.2% ≥75 years, 22.4% ECOG performance status ≥2) and effectiveness (n = 3570). The frequencies of any grade and grade 3 or higher treatment-related adverse events were 47.1% and 15.9%, respectively. The most frequent treatment-related adverse events (any grade) were interstitial lung disease (6.4%), hypothyroidism (5.7%), and diarrhea (4.4%). Treatment-related adverse events of special interest (priority items) occurring at a frequency of 5% or more were adverse events related to interstitial lung disease, thyroid dysfunction, liver dysfunction, colitis/severe diarrhea, infusion reaction, and infusion reaction within 24 hours. Significant risk factors for these priority items were identified by competing risk analysis: interstitial lung disease (previous/comorbid interstitial lung disease, abnormal findings on chest imaging, and smoking history); liver dysfunction (previous/comorbid liver disease, smoking history, and metastasis); thyroid dysfunction (previous/comorbid thyroid disease and performance status); and colitis/severe diarrhea (treatment line 2 vs ≥3). The 12-month survival rate was 40.7%. In conclusion, the safety profile of nivolumab in this postmarketing surveillance was similar to that in clinical trials, and no new safety signals were identified. The study was registered with the Japan Pharmaceutical Information Center (clinicaltrials.jp: Japic-163271).

RESUMO

BACKGROUND: Neutrophil-to-lymphocyte ratio (NLR) has recently attracted attention as a prognostic predictor in patients with non-small cell lung cancer (NSCLC) who receive immune checkpoint inhibitors (ICIs). However, the utility of NLR in relation to cytotoxic anticancer drugs or molecular targeted drugs remains unclear. We determined if NLR could predict the treatment efficacy and prognosis in NSCLC patients who receive cytotoxic anticancer drugs or molecular targeted drugs, as well as ICIs, in a cross-sectional manner. METHODS: Of 658 patients with advanced NSCLC who received first-line systemic treatment in our hospital between 2008 and 2019, 312 who met the analytical criteria were included in the study. We retrospectively analyzed the ability of NLR with a cut-off value of 5 to predict time to treatment failure (TTF) and overall survival (OS) in patients who received the following treatments: first-line treatment with molecular targeted drugs (mt group, n=100); first-line treatment with cytotoxic anticancer drugs (wt group, n=212); and first-line treatment with cytotoxic anticancer drugs followed by ICIs (ICI group, n=58). RESULTS: In the high- and low-NLR mt subgroups, median TTFs were 6.7 and 14.9 months (P<0.01), respectively, and median survival times (MSTs) were 17.8 and 39.1 months (P<0.01), respectively. In the high- and low-NLR wt subgroups, median TTFs were 1.5 and 5.8 months (P<0.01), and MSTs were 6.3 and 20.7 months (P<0.01), respectively. In the high- and low-NLR ICI subgroups, median TTFs were 1.3 and 6.8 months (P<0.01), and MSTs were 9.2 and 25.8 months (P<0.01), respectively. Multivariate analysis identified NLR as a significant independent predictor of TTF [hazard ratio (HR) 1.89, P=0.01; HR 2.51, P<0.01; and HR 5.06, P<0.01 in the mt, wt, and ICI groups, respectively) and OS (HR 3.81, P<0.01; HR 2.59, P<0.01; and HR 2.48, P<0.01, respectively). CONCLUSIONS: This study showed that NLR might be a predictor of treatment efficacy and prognosis in advanced NSCLC patients who receive various systemic treatments. This finding of consistent applicability of NLR to a wide variety of systemic treatments is of great significance.

RESUMO

Nivolumab can cause interstitial lung disease (ILD), which may be fatal; however, mortality risk factors have not been identified. This postmarketing study evaluated the poor prognostic factors of ILD in nivolumab-treated patients with non-small cell lung cancer (NSCLC) in Japan. Clinical and chest imaging findings for each ILD case were assessed by an expert central review committee, and prognosis was evaluated by radiographic findings, including the presence/absence of peritumoral ground-glass opacity (peritumoral-GGO). Poor prognostic factors were identified by univariate and multivariate Cox regression analysis. Of the 238 patients with nivolumab-induced ILD, 37 died. The main radiographic patterns of ILD were cryptogenic organizing pneumonia/chronic eosinophilic pneumonia-like (53.4%), faint infiltration pattern/acute hypersensitivity pneumonia-like (20.2%), diffuse alveolar damage (DAD)-like (10.9%), and nonspecific interstitial pneumonia-like (6.3%). The main poor prognostic factors identified were DAD-like pattern (highest hazard ratio: 10.72), ≤60 days from the start of nivolumab treatment to the onset of ILD, pleural effusion before treatment, lesion distribution contralateral or bilateral to the tumor, and abnormal change in C-reactive protein (CRP) levels. Of the 37 deaths due to ILD, 17 had DAD-like radiographic pattern, three had peritumoral-GGO, and five had a change in radiographic pattern from non-DAD at the onset to DAD-like. Patients with NSCLC who develop ILD during nivolumab treatment should be managed carefully if they have poor prognostic factors such as DAD-like radiographic pattern, onset of ILD ≤60 days from nivolumab initiation, pleural effusion before nivolumab treatment, lesion distribution contralateral or bilateral to the tumor, and abnormal changes in CRP levels.

RESUMO

Nivolumab, a human monoclonal antibody against programmed death-1, is approved for the treatment of non-small cell lung cancer (NSCLC). Although nivolumab is generally well tolerated, it can cause interstitial lung disease (ILD), a rare but potentially fatal immune-related adverse event. Currently, there are limited data available on the treatment of nivolumab-induced ILD and its outcome. This retrospective cohort study based on a post-marketing study described the treatment of nivolumab-induced ILD and its outcome in NSCLC patients in Japan through the assessment of clinical and chest imaging findings by an expert central review committee. Treatment details for patients who experienced a relapse of ILD were also analyzed. Of the 238 patients identified as having nivolumab-induced ILD, 37 patients died of ILD. Corticosteroids were used in 207 (87.0%) patients. Of those, 172 (83.1%) patients responded well and survived and 35 (16.9%) died (most died during corticosteroid treatment). A total of nine patients experienced a relapse; at the time of relapse, four patients were taking nivolumab. Of those who were receiving corticosteroids at the time of relapse, three of four patients were taking low doses or had nearly completed dose tapering. All patients (except one, whose treatment was unknown) received corticosteroids for the treatment of relapse, but one patient died. Patients with NSCLC who experience nivolumab-induced ILD are treated effectively with corticosteroids, and providing extra care when ceasing or reducing the corticosteroid dose may prevent relapse of ILD.

RESUMO

We herein report a case of breast cancer in a 74-year-old woman treated with exemestane as fourth-line hormonal therapy and bone-modifying agents for long time. She suddenly developed a right femoral shaft fracture during treatment. Her femoral fracture had a beaking sign on radiogram. Given this finding, her fracture was ultimately diagnosed as atypical femoral fracture (AFF). In this case, it was difficult to recognize the difference between groin pain as a prodromal symptom of AFF and that due to an adverse reaction to hormonal therapy. Therefore, clinicians should recognize the difficulty of this differentiation and consider the situation with caution.

RESUMO

Aim: To assess the clinical features/imaging characteristics of pneumonitis reported during nationwide nivolumab postmarketing surveillance in Japan. Patients & methods: Clinical and radiological data were collected from pneumonitis cases reported during/after nivolumab treatment for melanoma or non-small-cell lung cancer. The expert central review committee evaluated each case. Results: Among 144 cases analyzed, 91 (63.2%) had radiological patterns considered typical for drug-induced pneumonitis and 53 (36.8%) patients had previously unobserved patterns with one or more atypical features, including 23 cases (16.0%) with ground glass opacity confined to the area around the tumor (peritumoral infiltration). A higher proportion of patients with (vs without) peritumoral infiltration had an antitumor response to nivolumab. Conclusion: Images of nivolumab-induced pneumonitis showed previously unobserved radiological patterns.

RESUMO

The neo-aortic insufficiency in patients with hypoplastic left heart syndrome is an important sequela. We assessed the risks of the neo-aortic valve deterioration by the difference of initial palliations: Group I underwent primary Norwood (Nw) with systemic-to-pulmonary artery shunt (SPS), Group II underwent bilateral pulmonary artery banding (bPAB) and subsequent Nw with SPS (bPAB-Nw/SPS), Group III underwent bPAB and subsequent Nw with bidirectional Glenn (BDG) procedure (bPAB-Nw/BDG). The neo-aortic valve z score changes over time did not reach statistical significance in all groups (p = 0.43 for Group I, 0.20 for Group II, and 0.30 for Group III). The degree of neo-aortic valve insufficiency did not change significantly over time during this period except for Group III (p = 0.34 for Group I, 0.20 for Group II, and 0.02 for Group III). On the other hand, dimensions of the neo-aortic annulus and degrees of neo-aortic insufficiency did not differ significantly among the 3 groups at any pre-determined time. The presence or absence of incision into the sino-tubular junction at Nw did not affect the late neo-aortic valve z score or insufficiency. These data indicate that the difference of initial palliative procedures does not affect late neo-aortic valve insufficiency in Nw survivors. Because valve failure may develop in longer follow-up, further observation should be conducted.

RESUMO

For sebaceous carcinoma (SC), a rare malignant tumor, no standard chemotherapy regimen for patients with distant metastasis has been studied. We experienced a case of eyelid SC with multiple lung metastases that responded to combination chemotherapy with carboplatin and paclitaxel with 11-month progression-free survival (PFS). This patient also responded to second-line treatment with docetaxel, another taxane, with 7-month PFS, resulting in at least 18 months of survival at the time of reporting. This report shows that taxane-based chemotherapy may be effective for advanced SC, for which no standard therapy has been established.

RESUMO

We encountered a case of primary lung cancer complicated with membranous nephropathy as primary nephrotic syndrome. Because treatment approaches vary greatly for primary and secondary nephrotic syndrome, a renal biopsy was performed for diagnosis. Much time was required to make a definitive diagnosis of primary nephrotic syndrome, as opposed to paraneoplastic nephrotic syndrome. Consequently, the subsequent chemotherapy was ineffective and caused significant toxicity due to reduced performance status (PS) and progression of hypoalbuminemia. Therefore, it is imperative that a diagnosis be made and treatment be initiated without delay before PS declines and hypoalbuminemia progresses.

RESUMO

Common dermatological side-effects associated with erlotinib, epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI), include pruritus and skin rash, which are mediated by substance P, leading to the occasional discontinuation of cancer treatment. Aprepitant is an antagonist of neurokinin-1 receptor, through which substance P activates the pruritogens. Thus, aprepitant is expected to offer a promising option for the treatment of erlotinib-induced pruritus. However, the appropriate treatment schedule for aprepitant administration is under consideration. Here, we discuss the need for flexible adjustment of the treatment schedule for aprepitant administration against erlotinib-induced refractory pruritus and skin rush. A 71-year-old female smoker presented with stage IV EGFR-mutated lung adenocarcinoma. She was started on erlotinib at 150 mg/day. However, by 28 days, severe pruritus and acneiform skin rush resistant to standard therapies occurred, resulting in the interruption of erlotinib therapy. After recovery, she was restarted on erlotinib at 100 mg/day. However, severe pruritus and skin rush developed again within 2 weeks. Then, we started the first 3-day dose of aprepitant (125 mg on day 1, 80 mg on day 3, and 80 mg on day 5) based on the results of the previous prospective study, which showed the success rate of 100% with at least the second dose of aprepitant. However, the pruritus and skin rush exacerbated again within 4 weeks. Therefore, we started the second 3-day dose of aprepitant, but in vain. At this point, as the patient-centered medicine, bi-weekly schedule of the 3-day dose of aprepitant was considered and, then, adopted. As the results, the pruritus and skin rush remained well-controlled throughout the subsequent treatment with erlotinib.

RESUMO

In lung cancer, several potential mechanisms of intrinsic and acquired resistance to epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) have been explored, including mesenchymal-epithelial transition factor (MET) signaling pathway activation. On the other hand, vascular endothelial growth factor (VEGF) production of EGFR-mutated lung cancer cells is stimulated by predominantly activated MET signaling pathway. Therefore, the inhibition of VEGF axis as the downstream target of MET signaling pathway seems promising. Here, for the first time, we report the potential efficacy of combination therapy with bevacizumab and erlotinib in an EGFR-mutated NSCLC patient with MET amplification who showed intrinsic resistance to initial EGFR-TKI therapy. The patient was a 60-year-old male smoker, showing performance status (PS) 2, who presented with stage IV lung adenocarcinoma (cT4N2M1a) harboring the EGFR exon 19 deletion mutation. He was started on gefitinib at 250 mg/day. However, by 28 days, his symptoms further deteriorated along with the increased tumor size, resulting in PS 3. Then, repeat biopsy was performed, showing the positive MET amplification and the preserved EGFR exon 19 deletion mutation. Therefore, on the basis of the potential efficacy for activated MET signaling pathway as well as the confirmed safety by the known phase II trial for EGFR-mutated patients, the patient was started on combination therapy with bevacizumab at 15 mg/kg every 3 weeks plus erlotinib at 150 mg/day. By 21 days, his symptoms gradually improved along with the decreased tumor size, resulting in better PS with no severe toxicities.

RESUMO

We report on a patient with perimembranous ventricular septal defect and pulmonary hypertension. He underwent pulmonary artery banding followed by external stenting of the left bronchus because of secondary bronchomalacia. The external stent applied was a ringed expanded polytetrafluoroethylene graft, 10 mm in diameter and fixed at 8 points. Intracardiac repair was performed at the age of 2 years and the external stent was left in place. Since then, the patient has been healthy and computed tomography reveals that the external stent graft has retained function for over 20 years.
