Introduction There are few reports on indocyanine green fluorescence‐guided surgery in testis‐related diseases. Case presentation A 38‐year‐old man underwent orchiectomy for left testicular cancer. Pathological diagnosis was pT1 seminoma. Seven years after the surgery, solitary left external iliac lymph node metastasis was suspected. We decided to perform laparoscopic lymph node dissection combined with indocyanine green fluorescence injection. During the operation, we injected indocyanine green fluorescence into his left inner inguinal ring and found that the lymph node was directly drained from the injection point. The pathological diagnosis of the indocyanine green fluorescence‐positive left external iliac lymph node was testicular cancer metastasis. Conclusion We experienced a case of solitary left external iliac lymph node recurrence in testicular cancer. Using indocyanine green fluorescence injection, we could visualize the lymphatic drainage route, which helped us identify the lymph node as the primary landing site of metastasis.
Background: Although prostate cancer is a very common form of malignancy in men, the clinical significance of androgen deprivation therapy (ADT) with abiraterone acetate versus the nonsteroidal antiandrogen bicalutamide has not yet been verified in patients with high-risk metastatic hormone-sensitive prostate cancer (mHSPC).The present study was designed to initiate this verification in real-world Japanese clinical practice.Methods: We retrospectively analyzed the records of 312 patients with high-risk mHSPC based on LATITUDE criteria and had received ADT with bicalutamide (n = 212) or abiraterone acetate (n = 100) between September 2015 and December 2020. Bicalutamide was given at 80 mg daily and abiraterone was given at 1000 mg daily as four 250-mg tablets plus prednisolone (5-10 mg daily). Overall survival (OS), cancer-specific survival (CSS), and time to castration-resistant prostate cancer (CRPC) were compared. The prognostic factor for time to CRPC was analyzed by Cox proportional hazard model.Results: Patients in the bicalutamide group were older, and more of them had poor performance status (≧2), than in the abiraterone group. Impaired liver function was noted in 2% of the bicalutamide group and 16% of the abiraterone group (p < 0.001).Median follow-up was 22.5 months for bicalutamide and 17 months for abiraterone (p < 0.001). Two-year OS and CSS for bicalutamide versus abiraterone was 77.8% versus 79.5% (p = 0.793) and 81.1% versus 82.5% (p = 0.698), respectively. Median time to CRPC was significantly longer in the abiraterone group than in the bicalutamide group (NA vs. 13 months, p < 0.001). In multivariate analysis, Gleason score ≧9, high alkaline phosphatase, high lactate dehydrogenase, liver metastasis, and
Background Docetaxel‐related adverse events (AEs) such as neutropenia and febrile neutropenia (FN) can be life‐threatening. A previous in vivo study raised the hypothesis that the castration status affects the rate of hematologic AEs. We aimed to investigate the impact of castration status on the incidence of docetaxel‐related AE in metastatic prostate cancer (mPCa) patients. Methods We retrospectively analyzed the records of 265 mPCa patients treated with docetaxel, comprising 92 patients with metastatic hormone‐sensitive prostate cancer (mHSPC) and 173 patients with metastatic castration‐resistant prostate cancer (mCRPC) between January 2015 and December 2021. Common terminology Criteria for Adverse Events (CTCAE) was applied to evaluate AEs. We analyzed the differential incidences between mHSPC and mCRPC, and risk factors of hematologic and nonhematologic AEs using a logistic regression model. Results The rate of patients who received primary prophylaxis against neutropenia was higher in those with the mHSPC compared with those with the mCRPC (7.5% vs. 33%, p < 0.001). Among the patients without primary prophylaxis, incidence rates of severe neutropenia (CTCAE ≥ Grade3) and FN were 89% and 16% in patients with mCRPC compared to 81% and 18% in those with mHSPC. Logistic regression analysis revealed that age ≥ 75 years and failure to provide primary prophylaxis were independent risk factors of severe neutropenia (odds ratio [OR]: 2.39, 95% confidential interval [CI]: 1.10–5.18 and OR: 15.8, 95% CI: 7.23–34.6, respectively). Eastern Cooperative Oncology Group Performance Status (ECOG‐PS) ≧ 1 was an independent risk factor of FN (OR: 2.26, 95% CI: 1.13–4.54). Castration status (mHSPC vs. mCRPC) was not associated with the risks of severe neutropenia and FN. Conclusions Castration status did not affect the risk of severe neutropenia or FN in mPCa patients treated with docetaxel regardless of the disease state. Failure to provide primary prophylaxis and advanced patient age are independent risk factors of severe neutropenia; while patients with poor PS are more likely to develop FN. These findings may help guide the clinical decision‐making for proper candidate selection of docetaxel treatment.
Purpose The aim of this study was to investigate the oncologic efficacy of combining docetaxel with androgen deprivation therapy (ADT) versus nonsteroidal antiandrogen (NSAA) with ADT in patients with high-volume metastatic hormone-sensitive prostate cancer (mHSPC) with focus on the effect of sequential therapy in a real-world clinical practice setting. Methods The records of 382 patients who harbored high-volume mHSPC, based on the CHAARTED criteria, and had received ADT with either docetaxel (n = 92) or NSAA (bicalutamide) (n = 290) were retrospectively analyzed. The cohorts were matched by one-to-one propensity scores based on patient demographics. Overall survival (OS), cancer-specific survival (CSS), progression-free survival (PFS), including time to castration-resistant prostate cancer (CRPC), and time to second-line progression (PFS2) were compared. 2nd-line PFS defined as the time from CRPC diagnosis to progression after second-line therapy was also compared. Results After matching, a total of 170 patients were retained: 85 patients treated with docetaxel + ADT and 85 patients treated with NSAA + ADT. The median OS and CSS for docetaxel + ADT versus NSAA + ADT were not reached (NR) vs. 49 months (p = 0.02) and NR vs. 55 months (p = 0.02), respectively. Median time to CRPC and PFS2 in patients treated with docetaxel + ADT was significantly longer compared to those treated with NSAA (22 vs. 12 months; p = 0.003 and, NR vs. 28 months; p < 0.001, respectively). There was no significant difference in 2nd-line PFS between the two groups. Conclusions Our analysis suggested that ADT with docetaxel significantly prolonged OS and CSS owing to a better time to CRPC and PFS2 in comparison to NSAA + ADT in high-volume mHSPC.
