Surgical outcome of modified versus conventional parotidectomy in treatment of benign parotid tumors.

Our proposed modified technique includes creating a posterior pedicle parotid gland fascia flap without separating the great auricular nerve branches through an aesthetic incision. This fascial flap is sutured back to the parotid bed creating a barrier of the aberrant regeneration of sympathetic fibers thus, theoretically, decreasing the incidence of Freys syndrome.

Can we put a simplified algorithm for reconstruction of large scalp defects following tumor resection

BackgroundReconstruction of large scalp defects after tumor resection is a challenging problem. We aimed at putting an algorithm for reconstruction of those defects.MethodsForty-two patients with scalp malignancies were enrolled in this study. Tumors were resected to a 1 cm negative margin and defects were reconstructed according to their size and to patient general condition.ResultsNo peri-operative mortality was encountered. Usage of free flaps was superior in cosmoses and function with an acceptable rate of complications.Conclusionfor scalp defects wider than100 cm2, the best tool of reconstruction is free flaps. Pedicled distant flaps are reserved if free flaps are not feasible or failed. Split thickness skin grafts are cosmetically inferior and not suitable for recurrent and irradiated tumours and better reserved for patients who cannot tolerate major operations.

Pharyngoesophageal reconstruction after resection of hypopharyngeal carcinoma: a new algorithm after analysis of 142 cases

BackgroundThe aim of this study is to define an algorithm for the choice of reconstructive method for defects after laryngo-pharyngo-esophagectomy for hypopharyngeal carcinoma.MethodsOne hundred and forty two cases of hypopharyngeal carcinoma were included and operated on by either partial pharyngectomy, total pharyngectomy or esophagectomy. The reconstructive method was tailored according to the resected segment.ResultsPectoralis flap was used in 48 cases, free jejunal flap in 28 cases, augmented colon bypass in 4 cases, gastric pull up in 32 cases and gastric tube in 30 cases. Mean hospital stay was 12 days. Mortality rate was 10.6% and morbidity rate was 31.7%. Total flap failure occurred in 3 cases of free flap and one case of pectoralis flap. There were 23 cases of early fistula. Late stricture occurred in 19 cases, being highest with myocutaneous flap (early fistula 12/50 and late stricture 13/50).ConclusionFree jejunal flap was the flap of choice for reconstruction when the safety margin is still above the clavicle. In cases with added esophagectomy, we recommend gastric tube as a method of choice for reconstruction.

Metal-Induced Oxidative Stress in Egyptian Women with Breast Cancer

Some trace metals are toxic and claimed to be carcinogenic. The present work aimed to determine the levels of some trace metals in breast tissues (healthy and tumor specimens) and to evaluate their concentrations in relation to the oxidative stress status in breast cancer which is a major health problem among Egyptian women. This study included 127 female patients with breast swelling. Analysis of trace metals in breast tissue was done using Atomic Absorption Spectrophotometry (AAS). Lipid peroxidation and oxidative status were assessed. There were statistically high levels of iron, zinc and copper in the benign and malignant breast tissues in comparison to the control group. Higher Malondialdehyde (MDA) levels were detected in patients with breast tumors while Superoxide dismutase (SOD), Catalase (CAT), Glutathione peroxidase (GSH), Glutathione-S-transferase (GST) and Nitric oxide (NO) were low in comparison to the healthy group. In conclusion, the alteration of the elemental content in cancerous breast tissues and the disruption of oxidant/antioxidant balance highlight the role of trace metals in cancer development.

Therapeutic reduction mammoplasty in large- breasted women with cancer using superior and superomedial pedicles

BACKGROUND Surgical management of breast cancer in large-breasted women presents a real challenge. This study aims to evaluate the outcome of therapeutic reduction mammoplasty in large-breasted women with breast cancer using superior and superomedial pedicles, situated at any breast quadrant except for the central and upper medial quadrants. METHODS Fifty women with breast cancer and large breasts underwent simultaneous bilateral reduction mammoplasty. The weight of the tissue removed ranged from 550 g to 1050 g and the tumor-free safety margins by frozen section were in the range of 4 cm to 12 cm. RESULTS The age of the patients ranged from 36 to 58 (median 43) years and tumor size ranged from 1 cm to 4 cm. The cosmetic outcomes were excellent in 32 patients (64%), good in 15 (30%) patients, and fair in three patients (6%). The follow-up period was 8-36 (mean 20) months, with no local recurrence or systemic metastasis. CONCLUSION Therapeutic reduction mammoplasty using superior and superomedial pedicles was shown to be oncologically safer than traditional conservative surgery. This oncoplastic procedure yields a satisfactory esthetic outcome with lower morbidity in large-breasted women with breast cancer.

Combination of irinotecan and 5-fluorouracil with radiation in locally advanced rectal adenocarcinoma.

ObjectiveTo evaluate toxicity and efficacy of addition of weekly irinotecan to a regimen of chemoradiotherapy of 5-fluorouracil with concurrent pelvic radiation in patients with locally advanced rectal cancer.Patients and methodsBetween October 2006 and December 2009, 36 patients with non-metastatic rectal adenocarcinoma were treated with chemoradiotherapy of irinotecan (50 mg/m2 weekly), 5-fluorouracil (250 mg/m2 for 5 days/week) and pelvic radiation (45 Gy/1.8 Gy/fraction for 5 days/week) by 3D conformal radiotherapy.ResultsAll patients completed the planned treatment. After the chemoradiotherapy, overall clinical response rate was 55.5% and pathological complete was 16.7%. Neutropenia was the most common hematologic toxicity (58.3%) with grade III in 5.5% while among non hematologic toxicity, diarrhea was the most common reported one (63.9%) with grade III in 13.9% followed by nausea and vomiting (47.2%). After a median follow-up of 23 months, progression-free and overall survival estimates at 2 years were 72% and 91.7%, respectively. Distant relapses were recoded in 16.7%, the main distant failure sites were lung and liver, and local relapse was found in 5.6%.ConclusionCombined chemoradiotherapy of irinotecan, 5-fluorouracil and radiotherapy for locally advanced non metastatic rectal adenocarcinoma is effective and safe. A prospective, randomized trial is needed to confirm these results in larger numbers and to compare this regimen with other non-irinotecan-based chemoradiotherapy regimens.

Genetic polymorphisms of NFκB1-94ins/delATTG and NFκBIA-881A/G genes in Egyptian patients with colorectal cancer

To assess the association of genetic polymorphisms of NFκB1 and NFκBIA genes with the susceptibility to colorectal cancer (CRC). Subjects included 100 Egyptian patients with CRC (60 males and 40 females) in addition to 85 healthy controls (47 males and 38 females) from the same locality. For all participants, genetic polymorphisms of NFκB1-94ins/delATTG (rs28362491) and NFκBIA-881A/G (rs3138053) were detected by using restriction fragment length polymorphism polymerase chain reaction (RFLP–PCR). CRC patients showed a significantly higher frequency of the NFκB1-94ins/ins genotype than controls (30 vs. 4.7%) that was significant in the recessive (OR 17.69, 95% CI   5.41–57.82, p < 0.0001) and codominant models (OR   18.28, 95% CI   4.87–68.6, p < 0.0001). The NFκB1-94ins allele frequency was significantly higher among patients than controls (58 vs. 39%, OR  2.18, 95% CI  1.4–3.3, p = 0.0004). We also noticed that the genotype G/G of NFκBIA-881 polymorphism was present in patients (4%) while it was absent (0%) in controls with increased frequency of the NFκBIA-881G allele in patients compared to controls (23 vs. 14%, p = 0.041). These polymorphisms were more associated with smoking and advanced tumor staging. This study indicates that the NFκB1-94ins/ins genotype was associated with the risk of developing colorectal cancer in Egyptian subjects. Also, CRC cases showed an increase in the frequency of NFκBIA-881G allele but not reaching statistical significance for multiple comparisons.

Safety and esthetic outcomes of therapeutic mammoplasty using medial pedicle for early breast cancer

Background Although therapeutic mammoplasty (TM) was introduced for treatment of localized ductal carcinoma in situ and invasive breast carcinoma (stages I and II) in females with large breast size, the suitability of medial pedicle TM for treatment of breast tumors at different locations has not been established. The objective of this study was to assess the safety and esthetic outcome of medial pedicle TM for breast tumors at different locations. Methods The study was conducted from February 2012 to July 2014. Consecutive patients with early breast carcinoma with medium- and large-sized breasts, with or without ptosis, who were offered medial pedicle TM were included in the study. Patients who were not candidates for breast-conserving surgery or those with tumors located along the medial pedicle were excluded. All patients received immediate postoperative adjuvant chemoradiotherapy. Results Thirty patients with a mean age of 48.5 years received medial pedicle TM in the breast harboring the tumor or, additionally, the other breast (N=14). The tumors were in the upper (60.0%), lower (26.7%), and lateral (13.3%) quadrants. Minor complications occurred in five cases (5/30, 16.7%) in the ipsilateral and in two (2/14, 14.3%) contralateral breasts. No wound dehiscence or areolar necrosis was recorded. A total of 22 (73.3%) patients were scored as excellent cosmesis. After a median follow-up of 20 months, no locoregional recurrence or distant metastases were observed. Conclusion TM using a medial pedicle is a safe and appealing technique among women with tumors at different locations.

Accuracy of Sentinel Lymph Node Biopsy after Neoadjuvant Chemotherapy in Breast Cancer Patients; Single Center Experience

Purpose: Most important factor affecting prognosis of breast cancer is axillary nodal involvement. Several studies evaluated the accuracy of Sentinel lymph node biopsy in breast cancer patients post neoadjuvant chemotherapy. In this study, we will examine accuracy and feasibility of using Sentinel lymph node biopsy in predicting axillary lymph node status in breast cancer patients after neoadjuvant chemotherapy. Methods: 45 female patients with resectable, nonmetastatic breast carcinoma cases who received neoadjuvant chemotherapy were enrolled in this study according to the routine Mansoura Oncology Center—guidelines of management of breast cancer. Methylene blue dye used for detection of Sentinel lymph node. Results: Successful Sentinel lymph node detection was 82.2%. Skin involvement (T4 disease) were linked to a low identification (P = 0.005). False negative rate equals 11/27 = (40.7%).With advancement of the stage of the tumor, the incidence of false negative results increases significantly (p = 0.012) with 95% confidence interval; 1.2 - 5.4. Conclusion: Sentinel lymph node should be adopted to be the standard method for axillary staging with T1-3 tumors after receiving neoadjuvant chemotherapy, in T4 patients, it is associated with low detection rate & high false negative rate making it doubtful technique for axillary staging.

A Totally Laparoendoscopic Approach for Low Rectal Cancer with Inguinal Nodal Metastasis

BACKGROUND AND AIMS Isolated inguinal nodal metastasis from rectal cancer is rare with better oncological outcome in case of surgical resection. METHODS We report a rectal cancer case with inguinal nodal metastasis that was operated using a totally endoscopic approach. Laparoscopic intersphincteric resection was done for rectal cancer and video endoscopic inguinal lymphadenectomy (VEIL) for inguinal lymph nodes. The patient was presented to and managed in the Oncology Center, Mansoura University, Egypt. RESULTS The patient had an uneventful postoperative course with better outcome than open surgery. CONCLUSIONS Incorporation of minimally invasive approaches such as laparoscopy and VEIL in the management of inguinal nodal metastasis from rectal cancer can have a great impact on the patients quality of life without affecting the oncologic outcome.
