Hepatocellular carcinoma (HCC) is one of the major malignant diseases worldwide, characterized by growing incidence and high mortality rates despite apparent improvements in surveillance programs, diagnostic and treatment procedures, molecular therapies, and numerous research initiatives. Most HCCs occur in patients with liver cirrhosis, and the competing mortality risks from the tumor and the cirrhosis should be considered. Presently, previously identified risk factors, such as hepatitis virus infection, hepatic inflammation and fibrosis, and metabolic syndrome, may be used as chemoprevention targets. The application of precision medicine for HCC management challenges the one-size-fits-all concept; moreover, patients should no longer be treated entirely according to the histology of their tumor but based on molecular targets specific to their tumor biology. Next-generation sequencing emphasizes HCC molecular heterogeneity and aids our comprehension of possible vulnerabilities that can be exploited. Moreover, genetic sequencing as part of a precision medicine concept may work as a promising tool for postoperative cancer monitoring. The use of genetic and epigenetic markers to identify therapeutic vulnerability could change the diagnosis and treatment of HCC, which so far was based on Barcelona clinic liver cancer (BCLC) staging. In daily clinical practice, the shift from a stage-oriented to a therapeutic-oriented approach is needed to direct the choice of HCC treatment toward the potentially most effective option on an individual basis. The important factor in precision medicine is the promotion of patient management based on the individual approach, knowing that the final decision must be approved by a multidisciplinary expert team.

Background: The number of elderly patients with HCC who undergo liver resection is increasing. Because of the advanced age of the patients, increased postoperative morbidity and reduced overall survival are expected in this population. The study aim was to compare clinicopathologic and operative features, short- and long-term outcomes among hepatocellular carcinoma (HCC) patients from three age groups undergoing potentially curative liver resection in a developing country. Methods: Prospectively collected data relating to 229 patients who underwent curative-intent liver resection from January 2009 until December 2018 were analyzed. The patients were divided into two age groups: G1 was below 70 years old (n=151) and G2 was 70 years old and older (n=78). Demographic, clinical, operative data, short- and long-term outcomes were compared between the two groups. Univariate and multivariate analyses of prognostic factors were performed. Results: The mean overall morbidity rate of the patients was 31.1% (G1), and 46.2% (G2) by age group. Postoperative morbidity was significantly higher in the G2 group (p=0.03). There was no difference in major morbidity between the two groups (p=0.214). No significant difference in mortality rate and overall survival was found between the study groups (p=0.280, p=0.383). Both age ≥ 70 years (ie, G2 group) and liver cirrhosis were identified as prognostic factors for postoperative morbidity, and a Child-Pugh score B as a negative prognostic factor for overall survival. In subgroup analysis of patients with cirrhosis, age ≥ 70, diabetes mellitus and perioperative transfusion were identified as prognostic factors for postoperative morbidity. Conclusion: The study confirmed the safety and feasibility of liver resection in elderly patients with HCC. However, appropriate patient selection among the elderly is mandatory in order to improve short- and long-term outcomes.

Background: The aims of this study were to present the concept of original technique in the management of major incisional subcostal hernias and to evaluate short- and long-term outcome. Method: Between January 2010 and January 2020, 280 patients underwent hernia repair surgery for incisional lateral abdominal hernia at Clinic for Digestive Surgery, Clinical Center of Serbia. Among them, 37 patients underwent the modified sublay technique for major incisional subcostal hernia with minimal hernia defect surface of 100 cm² or greater or minimal hernia defect width or height of 10 cm or greater. The operative techniques are as follows: retromuscular dissection of rectus muscle from posterior sheath on the both sides of hernia defect, external oblique muscle dissection from internal oblique muscle in a circle around hernia defect at the side of the hernia defect, complete reconstruction of the posterior myofascial layer, large heavyweight polypropylene mesh placement in a sublay position, and complete or partial reconstruction of anterior myofascial layer. Results: A median (range) hernia defect surface was 150 (100–500) cm². A median operative time was 130 (90–330) minutes. The morbidity rate was 18.9%. A median (range) postoperative hospital stay was 7 (2–24) days. After the median follow-up of 50 (1–108) months, 2 patients (5.4%) developed recurrent hernia. Conclusions: The modified sublay technique using large heavyweight polypropylene mesh provides good results in the management of major subcostal abdominal wall defects.

Gastrointestinal stromal tumors (GISTs) are rare mesenchymal tumors primarily located in the stomach and small intestine; their occurrence in the terminal ileum is particularly rare. Although GISTs can develop throughout the gastrointestinal tract, cases of perforation in elderly individuals are even less common, posing significant diagnostic and therapeutic challenges. This case report describes an 86-year-old male patient with an acute abdomen caused by a terminal ileum perforated GIST requiring urgent surgical intervention. An immunohistochemical examination of the tumor confirmed a GIST with a GILT (gastrointestinal leiomyogenic tumor) immunophenotype. The rarity of this condition makes it diagnostically challenging, as its symptoms are often nonspecific, and GISTs are frequently overlooked, particularly in older patients. This case supplements the existing literature by emphasizing the importance of considering GIST perforation in the differential diagnosis of an acute abdomen, even in elderly patients and in rare anatomical locations.
