Summary Background 80% of individuals with cancer will require a surgical procedure, yet little comparative data exist on early outcomes in low-income and middle-income countries (LMICs). We compared postoperative outcomes in breast, colorectal, and gastric cancer surgery in hospitals worldwide, focusing on the effect of disease stage and complications on postoperative mortality. Methods This was a multicentre, international prospective cohort study of consecutive adult patients undergoing surgery for primary breast, colorectal, or gastric cancer requiring a skin incision done under general or neuraxial anaesthesia. The primary outcome was death or major complication within 30 days of surgery. Multilevel logistic regression determined relationships within three-level nested models of patients within hospitals and countries. Hospital-level infrastructure effects were explored with three-way mediation analyses. This study was registered with ClinicalTrials.gov , NCT03471494 . Findings Between April 1, 2018, and Jan 31, 2019, we enrolled 15 958 patients from 428 hospitals in 82 countries (high income 9106 patients, 31 countries; upper-middle income 2721 patients, 23 countries; or lower-middle income 4131 patients, 28 countries). Patients in LMICs presented with more advanced disease compared with patients in high-income countries. 30-day mortality was higher for gastric cancer in low-income or lower-middle-income countries (adjusted odds ratio 3·72, 95% CI 1·70–8·16) and for colorectal cancer in low-income or lower-middle-income countries (4·59, 2·39–8·80) and upper-middle-income countries (2·06, 1·11–3·83). No difference in 30-day mortality was seen in breast cancer. The proportion of patients who died after a major complication was greatest in low-income or lower-middle-income countries (6·15, 3·26–11·59) and upper-middle-income countries (3·89, 2·08–7·29). Postoperative death after complications was partly explained by patient factors (60%) and partly by hospital or country (40%). The absence of consistently available postoperative care facilities was associated with seven to 10 more deaths per 100 major complications in LMICs. Cancer stage alone explained little of the early variation in mortality or postoperative complications. Interpretation Higher levels of mortality after cancer surgery in LMICs was not fully explained by later presentation of disease. The capacity to rescue patients from surgical complications is a tangible opportunity for meaningful intervention. Early death after cancer surgery might be reduced by policies focusing on strengthening perioperative care systems to detect and intervene in common complications.

Female breast cancer is the most common tumour diagnosed worldwide and is one of the leading causes of cancer-related death. The management of elderly, male and pregnant patients with breast cancer requires some additional considerations which are reviewed in this chapter. Breast screening is routinely offered to women aged between 50 and 70 years in England. There are substantial regional variations among UK hospitals in the clinical management of elderly breast cancer patients. Primary endocrine therapy is used in the treatment of ERpositive elderly breast cancer patients not fit for surgical intervention. Male breast cancer is rare, accounting for less than 1% of all breast cancers. It is more common in elderly men and tends to behave like post-menopausal breast cancer. Although breast cancer is one of the most frequently diagnosed malignancies among pregnant women, breast cancer during pregnancy is a rare condition and has been associated with more aggressive, high-grade, poorly differentiated tumours and with a predominance of more aggressive molecular subtypes such as triple negative, HER-2-positive and lower rates of ER and PR expression.

Introduction: Abdominal tuberculosis (ATB) is a rare extrapulmonary manifestation of Mycobacterium tuberculosis infection. It usually presents with nonspecific symptoms that can mimic other intra-abdominal conditions like acute appendicitis, Crohn's disease, ovarian pathology, and intra-peritoneal carcinomatosis and is therefore, easy to overlook. Diagnosing ATB in the pediatrics population tends to be even more challenging as an obvious history of exposure may be difficult to obtain. Chronicity of symptoms and lack of Bacillus Calmette-Guérin (BCG) scar should raise suspicion. Diagnostic laparoscopic biopsy and histopathology provides definitive diagnosis.Case Report: This case report presents the case of a 16-year-old girl with a history of recurrent abdominal pain, vomiting, and pyrexia. At initial diagnostic laparoscopy, she underwent laparoscopic appendectomy. Vesicles were noted in the pelvis. The patient failed to improve. Exposure to tuberculosis (TB) was denied. Review of preoperative computed tomography (CT), comprehensive re-laparoscopy, and histopathology of appendix were used for final diagnosis of this condition. The patient was treated using anti-TB therapy for six months following which, she was able to make a full recovery. Conclusion:Abdominal TB is very difficult to diagnose in young patients and should be considered in those
