    Abstract Introduction: Nontraumatic biliary rupture and retroperitoneal biloma infrequently occur. Here, we report a case of retroperitoneal biloma due to spontaneous left hepatic duct perforation, which was difficult to differentiate from a perirenal abscess.
    Case presentation: A 94-year-old female patient was hospitalized with symptoms of fatigue and right back pain that lasted for 5 days. Computed tomography revealed fluid accumulation in the retroperitoneum, and urinary extravasation and right perinephric abscess were suspected. Antimicrobial treatment and drainage with ureteral stents and urethral catheters demonstrated no symptom improvement. Ultrasound-guided puncture of the abscess revealed the presence of bile. Pigtail catheter drainage improved symptoms and inflammatory response. After diagnosis, endoscopic retrograde cholangiopancreatography revealed bile leakage, and a bile duct stent was inserted.
    Conclusion: Biloma can cause perirenal fluid accumulation, and they should be considered an origin of perirenal fluid accumulation when urinary tract lesions are excluded.

    Abstract Introduction: Sigmoid conduit is one of the methods for achieving urinary diversion, but it is performed less frequently than ileal conduit and ureterostomy. Herein, we report a case in which a sigmoid colon conduit was performed after nephrostomy and transverse colostomy.
    Case presentation: A 70-year-old man was referred to our hospital because of a bladder tumor. Computed tomography and transurethral biopsy revealed advanced bladder cancer with ureteral and rectal invasion. Despite drug therapy, the tumor progressed. Thus, nephrostomy and transverse colostomy were performed for urinary and fecal diversion, respectively. Subsequently, chemotherapy was administered for 8 months. As nephrostomy-related complications occurred frequently during chemotherapy, a sigmoid colon conduit was performed instead of nephrostomy for urinary diversion to improve the patient's quality of life.
    Conclusion: In patients with advanced bladder cancer requiring a double stoma of the urinary and fecal tracts, sigmoid colon conduit may be selected as a urinary diversion method.

    Methods: OAB patients aged ≥ 80 years were enrolled in this prospective, single-arm observational study. OAB was diagnosed based on the OAB symptom score (OABSS); i.e., a total score of ≥ 3 points and an urgency score of ≥ 2 points. Patients who received 50 mg mirabegron once daily were evaluated at the baseline and at 4, 8, and 12 weeks. The changes from the baseline in the OABSS, International Prostate Symptom Score (IPSS), OAB questionnaire (OAB-q) score, and Vulnerable Elders Survey (VES-13) score were determined. Adverse events, laboratory tests, 12-lead electrocardiography, the QT interval according to Fridericia's formula (QTcF), uroflowmetry, the post-void residual urine volume (PVR), and the Mini-Mental State Examination (MMSE) score were used to assess safety.
    Results: Forty-three patients (median age: 84 years, range: 80-96 years) were examined. They had high rates of comorbidities and polypharmacy. Mirabegron significantly improved in total score of the OABSS, including urgency and urge incontinence. The total IPSS, IPSS quality-of-life (QOL) index, and OAB-q scores also significantly improved. Mirabegron improved in the VES-13 score. There were no significant changes in laboratory test values, uroflowmetry findings, PVR, the QTcF, or MMSE score. Two patients (4.7%) withdrew from the study after experiencing adverse events.
    Conclusions: Mirabegron was well tolerated and significantly improved in OAB symptoms, and QOL in older patients. Trial registration The present clinical study was approved by University of Yamanashi Institutional Review Board prior to study initiation (ID1447) and was retrospectively registered with the UMIN Clinical Trials Registry (UMIN-CTR), Japan (UMIN000045996) on Nov 6, 2021.

    Abstract Purpose: Ipsilateral breast tumor recurrence (IBTR) after breast-conserving therapy is seen after a long interval, but the clinical classification of Residual Tumor Recurrence (RR) or Double Primary (DP) needs to be validated. We used genome profiling to identify the genetic alterations associated with IBTR.
    Methods: Among 1881 breast cancer patients treated with breast-conserving therapy between 1999 and 2018, IBTR occurred in 52 patients (2.8%). Of these 22 patients who consented for genomic analysis of Primary Breast Cancer (T1) and IBTR (T2) were studied. When the same gene mutations in T1 and T2 were identified, it was classified as genomic residual recurrence gRR, and when no shared mutations identified, it was classified as gDP. The differences between clinical and genomic classification were compared. Furthermore, the pathway of the genes which were responsible for recurrence was also examined.
    Results: Of 13 clinically diagnosed RRs (cRRs), 11 were gRR and 2 were gDPs, while of 9 cDPs, 6 were gDP and 3 gRR, with a match rate of 17/22 (77%). We searched for genes involved in IBTR: PIK3CA-AKT pathway mutations were found in 12 of 14 gRRs (86%) in T1, and only 2 of 8 gDPs (25%) with significant difference (p = 0.004). When both of PBC and IBTR compared, PIK3CA-AKT pathway abnormalities were 24/28 (86%) in the gRR and 5/16 (31%) in the gDP (p < 0.001).
    Conclusions: Genome profiling revealed that abnormalities in the PIK3CA-AKT pathway in long-term residential recurrences and are a crucial molecular group in the development of IBTR.

    Abstract The benefit of home parenteral nutrition (HPN) for patients with malnutrition due to peritoneal metastasis depends on the type of cancer. During the period 1999-2020, we treated 460 patients with metastatic and stage 4 breast cancer, 23 of whom were invasive lobular carcinoma (ILC). Of the 23 patients with ILC, 13 (57%) developed peritoneal metastasis, and 11 died of progression of peritoneal metastasis. Among these 11 patients, 2 patients who underwent surgery due to bowel obstruction, had no improvement, and died 1-4 months after surgery. The prognosis of the other 7 patients under BSC alone was poor, survival time were ranging from 1 to 5 months. The remaining two patients who were able to continue outpatient chemotherapy under HPN were able to prolong their survival time by 18 months and 26 months, respectively. We need to recognize that HPN and chemotherapy may prolong survival time in patients with peritoneal metastasis of ILC, and determine the indication for HPN based on the non-peritoneal life-threatening metastasis, length of treatment, availability of support for HPN management and outpatient chemotherapy, and the patient's willingness to accept it.

    Abstract Neo-adjuvant chemotherapy (NAC) has become a standard treatment for advanced breast cancer because of the advantage of monitoring drug sensitivity and enabling breast-conserving therapy. The changes during NAC are also important to know the biological characteristics of the tumor. We experienced two cases with cystic degeneration and enhancement of the cyst wall during NAC for triple negative breast cancer (TNBC). They were diagnosed to have breast cancer with squamous metaplasia. In case 1, a 37-year-old woman with right breast cancer diagnosed as TNBC, T3N3M0, Stage 3b was treated with NAC. MRI showed a cystic degeneration with a diameter of 3.5 cm and enhancement of the cyst wall, and the other nodules were extinguished. The histopathological finding of the surgical specimen revealed solid tubular carcinoma with squamous metaplasia. In case 2, a 58-year-old woman with right breast cancer diagnosed as HER2 enriched subtype, T2N0M0 stage 2 was treated with NAC containing trastuzumab. The post-NAC MRI showed extinguishment of the mass in the right breast, but showed a cystic lesion with 24 mm in diameter and enhancement of its wall in the left breast. She underwent breast conserving surgery for bilateral breast cancer, and histopathological finding of the surgical specimen indicated complete remission of right breast cancer and squamous cell carcinoma developed in the left breast. These changes are impressive and remind us that there are metaplastic changes (especially for squamous metaplasia) with resistance to chemotherapy.

    Abstract Purpose: The prognosis of HER2-positive breast cancer has improved with the development of anti-HER2 therapies. In order to further improve the prognosis of HER2-positive breast cancer, it is essential to elucidate the cells that survive during the therapy (drug-tolerant persister DTP).
    Methods: Of the 2022 breast cancer patients operated at our institution during 2004-2018, 240 (12%) had HER2-positive breast cancer. Neo-adjuvant chemotherapy including trastuzumab (Tr-NAC) was administered to 94 of them. Forty-six of them were complete remission (CR), and 48 were non-CR. After 6.9 ± 3.7 years of follow-up, all 46 CR cases showed no recurrence (Cohort A), and 48 non-CR cases were divided into 31 cases with no recurrence (Cohort B) and 17 cases with recurrence (Cohort C). In addition to clinical backgrounds, we compared genomic profiles for 27 patients (Cohort A; 15/48, B; 7/31, and C; 5/17) who consented to genomic analysis.
    Results: Genomic abnormalities of TP53 and PIK3CA were frequently observed in biopsy samples pre Tr-NAC, but we found no differences between CR (Cohort A) and non-CR (Cohorts B + C). Then, we examined both of pre and post Tr-NAC samples of Cohort B (7) and C (5) to see the relationship between recurrence and genomic abnormalities. TP53 mutations were significantly more prevalent in Cohort C (5/5, 100%) than cohort B (3/7, 43%) in the surgical sample after treatment (p = 0.04). PyClone analysis of TP53 mutations showed that the cellular frequency of TP53 clones increased in 4 of 5 patients in Cohort C and none of B. On the other hand, we found no enhancement of PIK3CA mutant clones in Cohort C.
    Conclusions: The DTP after Tr-NAC associated with subsequent relapse had TP53 mutations, suggesting that overcoming DTP with TP53 mutations is the most important clinical challenge.
    Trial registration: Not applicable.

    Abstract Introduction: Hepatic portal venous gas (HPVG) is believed to be an indication for emergent surgery because it is associated with high mortality rate. However, the recent increase in the use of modern abdominal computed tomography (CT) has resulted in the detection of HPVG in more benign conditions. Therefore, the decision-making process whether we chose emergent surgery or conservative treatment without surgery is important for the patients with HPVG.
    Case presentation: An 84-year-old male was referred to our hospital due to the sudden onset of abdominal pain and massive hepatic portal vein gas on emergent CT. The Acute Physiology and Chronic Health Evaluation (APACHE) II Score was calculated as 17; slightly elevated comparing with the other cases who were successfully treated without surgery. Although the PHVG was remained at follow up CT on the next day after the onset, the symptoms were improved. We selected conservative treatment without emergent surgery and he discharged on 9
    Conclusions: The clinical finding of this case showing subtle differences from cases who were successfully treated without surgery. We hope this report will help physician's decision-making process for HPVG.

    Abstract Background: To investigate the feasibility of the fourth arm of the da Vinci Si system for robot-assisted partial nephrectomy (RAPN).
    Methods: Fifty-eight consecutive patients underwent RAPN with the same port placements. After reviewing the surgical videos and records, 38 patients showing usefulness of the fourth arm were categorized into Group A and those not showing usefulness into Group B. The background data, tumor characteristics, and perioperative outcomes were compared between the groups.
    Results: Group B had a larger proportion of tumors located on the inner side of the kidney, and the console time was significantly longer. Multivariable logistic regression analysis showed that tumors located on the inner side of the kidney were associated with the non-use of the fourth arm of the da Vinci Si system during RAPN.
    Conclusions: Our findings suggested that use of fourth arm in RAPN by da Vinci Si should be considered for each tumor location.
