Cancers 15 ( 6 ) 1740 2023.3

Background: This study aims to clarify the perioperative risk factors and short-term prognosis of central bisectionectomy (CB) for hepatocellular carcinoma (HCC). Methods: Surgical data from 142 selected patients out of 171 HCC patients who underwent anatomical CB (H458) between 2005 and 2020 were collected from 17 expert institutions in a single-arm retrospective study. Results: Morbidities recorded by the International Study Group of Liver Surgery (ISGLS) from grade BC post-hepatectomy liver failure (PHLF) and bile leakage (PHBL), or complications requiring intervention were observed in 37% of patients. A multivariate analysis showed that increased blood loss (iBL) > 1500 mL from PHLF (risk ratio [RR]: 2.79), albumin level < 4 g/dL for PHBL (RR, 2.99), involvement of segment 1, a large size > 6 cm, or compression of the hepatic venous confluence or cava by HCC for all severe complications (RR: 5.67, 3.75, 6.51, and 8.95, respectively) (p < 0.05) were significant parameters. Four patients (3%) died from PHLF. HCC recurred in 50% of 138 surviving patients. The three-year recurrence-free and overall survival rates were 48% and 81%, respectively. Conclusions: Large tumor size and surrounding tumor involvement, or compression of major vasculatures and the related iBL > 1500 mL were independent risk factors for severe morbidities in patients with HCC undergoing CB.

Purpose: We used a novel diagnostic Fourier transform (FT) algorithm of the entire extrahepatic bile duct (EHBD) measured by magnetic resonance cholangiography (MRC) to evaluate subtle deformation of bile duct lumen, indicating the malignant potential of EHBD, in patients with pancreaticobiliary maljunction (PBMJ) and in a comparative group of controls without PBMJ. Methods: From the workstation, the EHBD lumen was traced automatically and a 2D diagram cross section was measured at 0.5 mm-longitudinal intervals. The FT-based integrated power spectral density function value (FTPSDI) of the diameter or area (mm2 or mm4/Hz) and the phase value distribution entropy (PVDE) were also measured. Results: There were 16 patients with undilated PBMJ and 7 with dilated PBMJ. The control group comprised 10 patients with a normal bile duct, 20 with bile duct carcinoma (BDC), and 1 with primary sclerosing cholangitis. Both the diameter and area of the dilated bile ducts and the ducts with early- or advanced-stage BDC were significantly greater than those of the normal duct (p < 0.05). The undilated type of PBMJ tended to have a larger FTPSDI diameter than a normal bile duct, which had a smaller diameter than the dilated type of PBMJ or BDC. BDC had a significantly larger FTPSDI diameter (p < 0.05) and the cutoff value for accuracy was 168 mm2 Hz−1. Conclusion: The novel mathematical FTPSDI is a promising indicator of whether preventive EHBD resection is necessary for patients with PBMJ, which can be widely applied in the early diagnosis of other biliary diseases.

Therapeutic applications: Photodynamic therapy using porphyrin compounds

As a result of recent advances in endoscopes and optical fibers, optical engineering has been introduced to medical treatment in these years. Photodynamic therapy (PDT) is a promising treatment method that irradiates a tumor with a highly tumor-accumulating photosensitive agent and a laser with a specific wavelength and shows a cell-killing effect only on tumor cells with high drug concentration. It has already been applied clinically in the fields of pulmonary and digestive surgery, neurosurgery, ophthalmology, dermatology, and urology. As described in other chapters, photodynamic diagnosis (PDD), which is a method to diagnose the localization of tumors by irradiating biological tissues with light and detecting the fluorescence generated by photosensitive agents accumulated in tumors, is also being actively studied and applied clinically.

<i>Purpose</i>: Central venous catheters (CVCs) are used in the treatment of pediatric hematological and oncological diseases. Recently, the ultrasound (US)-guided supraclavicular approach to brachiocephalic vein cannulation with in-plane views has been described as a safe central venous catheterization technique.<i>Methods</i>: A retrospective study was performed on patients who underwent US-guided tunneled CVC insertion into the internal jugular vein with out-of-plane views (IJV group) and the brachiocephalic vein with in-plane views (BCV group). The patients’ background characteristics, surgical outcomes, and complications were compared retrospectively.<i>Results</i>: A total of 40 tunneled CVCs (IJV group: n = 15, BCV group: n = 25) were inserted in 34 patients. The patients’ background characteristics were not significantly different between the two groups. The operative times were 30 min (range: 27–33 min) in the IJV group and 25.8 min (range: 22–27 min) in the BCV group. The BCV group had a significantly shorter operative time (p = 0.0026). Intraoperative complications were observed in one patient (6.7%) in the IJV group and none of the patients in the BCV group. Complications during maintenance were observed in 10 patients (66.7%) in the IJV group and 17 patients (68%) in the BCV group. Catheter-related bloodstream infection was noted in 10 patients (66.7%) in the IJV group and 12 patients (52%) in the BCV group; these infection rates were not significantly different. The periods of CVC implantation were 273 days (172–363.5 days) in the IJV group and 152 days (101–280 days) in the BCV group, which were not significantly different.<i>Conclusions</i>: A real-time US-guided supraclavicular approach to brachiocephalic catheterization was considered a safe technique for pediatric patients with hematological and oncological diseases.

光線力学的療法は、切除不能胆管癌に対する補助化学療法として効果が期待できる。一方で、光線過敏症などの副作用もあり、腫瘍特異成・抗腫瘍効果が高く副作用の少ない光感受性物質の開発がのぞまれる。新規光感受性物質と期待される糖鎖連結クロリンを用いた胆道癌に対する光線力学的療法について、現在使用されているタラポルフィリンナトリウム（レザフィリン）と比較検討した。細胞を用いた実験では、殺細胞効果・アポトーシス誘導効果が高いことが分かり、糖鎖連結クロリンが新規光感受性物質として期待できるという結果を得た。
