Background Childhood parotid neoplasms appear to have different characteristics from adults. This point, in addition to the rarity of these tumors, reflects the challenges faced in diagnosing and treating parotid neoplasms in children. Patients and methods This retrospective study included all children who presented to the Children’s Cancer Hospital Egypt (CCHE, 57357) with parotid masses from January 2008 to December 2020. Results Twenty-one patients were included. Malignant neoplasms were found in 12 (57.1%) of which mucoepidermoid carcinoma was the most common. Benign neoplasms were found in 6 (28.6%) all of them were pleomorphic adenoma, and non-neoplastic lesions were found in 3 (14.3%). Superficial, deep, or total parotidectomy was performed according to the involved lobes. The facial nerve was sacrificed in three cases because of frank invasion by the tumor. Neck dissection was considered in clinically positive lymph nodes and/or T3/4 masses. Complications occurred in 7 (33.3%) all were of the malignant cases. Adjuvant radiotherapy was restricted to high-risk cases (7 cases). Recurrence occurred in two cases, and one patient died of distant metastasis. Fine needle aspiration cytology (FNAC) showed 88.9% sensitivity and 100% specificity for diagnosing malignant neoplasms. The correlation of radiological and pathological staging was fair (66.74% for overall staging). Conclusions Parotidectomy is the backbone treatment for benign and malignant pediatric parotid tumors. Neck nodal dissection should be considered after preoperative FNAC of suspicious nodes. Adjuvant radiotherapy is considered only in high-risk tumors. Preoperative FNAC of parotid masses and clinically suspicious lymph nodes is highly recommended.
Background and aim Neoadjuvant chemotherapy (NAC) before radical cystectomy (RC) became the standard of care for muscle-invasive bladder cancer (MIBC) in the last few years. We aimed to evaluate the radiological, pathological responses to NAC, and the 30-day surgical outcomes after RC in MIBC. Patients and methods A retrospective cohort study involving adult patients with localized urothelial MIBC who received NAC followed by RC at the National Cancer Institute of Egypt (NCI-E) for 2 years (2017 and 2018). Out of 235 MIBC cases, we recognized 72 patients (30%) who fitted the eligibility criteria. Results A cohort of 72 patients with a median age of 60.5 years (range 34–87). Hydronephrosis, gross extravesical extension (cT3b), and radiologically negative nodes (cN0) were depicted initially in 45.8, 52.8, and 83.3% of patients, respectively. Gemcitabine and cisplatin (GC) was the rampant NAC employed in 95.8%. Radiological evaluation post NAC using RECIST v1.1 revealed a response rate (RR) of 65.3% in bladder tumor and progressive disease in the former and lymph nodes encountered in 19.4 and 13.9%, respectively. The median time from the end of NAC to surgery was 8.1 weeks (range 4–15). Open RC and ileal conduit were the most common types of surgery and urinary diversion, respectively. Pathological down-staging was encountered in 31.9%, and only 11 cases (15.3%) achieved pathological complete response (pCR). The latter was significantly correlated with the absence of hydronephrosis, low-risk tumors, and associated bilharziasis (p = 0.001, 0.029, and 0.039, respectively). By logistic regression, the high-risk category was the only independent factor associated with a poor likelihood of achieving pCR (OR 4.3; 95% CI 1.1–16.7; p = 0.038). Thirty-day mortality occurred in 5(7%) patients, and 16(22%) experienced morbidity, with intestinal leakage being the most frequent complication. cT4 was the only significant factor associated with post-RC morbidity and mortality compared to cT2 and cT3b (p = 0.01). Conclusions Our results are further supporting the radiological and pathological benefits of NAC in MIBC, evidenced by tumor downstaging and pCR. The complication rate after RC is still considerable; hence, more larger studies are necessary to postulate a comprehensive risk assessment tool for patients who would get the maximum benefit from NAC, hoping to accomplish higher complete response rates with ultimately increased adoption of the bladder preservation strategies.
Background: Inguinal lymphadenectomy has always been associated with a high complication rate, mostly related to wound healing. Objectives: We aimed at evaluating the skin excision vertical incision in lowering wound complication rate following inguinal lymphadenectomy. Patients and Methods: Patients underwent inguinal lymphadenectomy for malignant nodal metastasis at the National Cancer Institute, Cairo University, Egypt in the period from January 2017 to December 2020. According to the incision type, we divided them into three groups: Group 1: vertical with vertical skin ellipse (~4cm) excision. Group 2: vertical S-shaped without skin excision.Group 3: transverse incision. We compared the short-term outcome among these groups. Results: Seventy-eight patients included, 27 (34.6%) G1, 27 (34.6% G2), and 24 (30.8%) G3. Complications occurred in a total of 20 cases (25.6% ). Its rate was highest in G3 (37.5% of cases) and least in G1 (14.8%). Flap necrosis was a common serious complication. It least occurred in the G1 Group and most in the G3 Group. No statistical difference was noticed regarding the median operation time, postoperative hospital stay, and median duration before drain removal. Capsular rupture did not occur in G1 patients, occurred only in one case of G2 (3.7%) and 2 cases of G3 ( 8.3%). Despite being statistically insignificant it is very significant oncologically. Conclusions: Vertical elliptical skin wedge excision in inguinal lymphadenectomy provides better surgical field exposure. It avoids direct handling of the tumor; thus is more safe oncologically. It has the least flap necrosis rate among other incision types.
