Preoperative localization of sentinel lymph node in breast cancer patients by silver wire insertion or liquid charcoal injection guided by CT lymphography.

Dual localization of SLN in breast cancer patients using isotope & dye is the best-approved modality with limitations such as high cost of radioactive materials, complex logistic preparations & scheduling issues, especially in developing countries. We investigated the feasibility & accuracy of a novel technique for SLN localization using silver wire insertion or liquid charcoal injection guided by CT lymphography. 120 patients with clinically node-negative breast cancer were enrolled. In the test group, SLN was localized using preoperative CTLG guided injection of liquid charcoal or by placing a 3 cm silver wire. In addition, intraoperative SLN mapping was performed using methylene blue dye followed by searching for the SLN localized by both methods. In the control group, SLN was localized by the blue dye only. Feasibility, accuracy, detection rates, and number of SLNs retrieved were reported as well as matching between the LN detected with the CTLG and that detected with the dye technique. SLN could be detected in 59 out of 60 patients (98.3%) in the test group and in 54 out of 60 patients (90%) in the control group (P = .057). In self-controlled analysis of the test group comparing CTLG only to dye only was significant (P = .050). Comparing charcoal to silver wire in detection was statistically insignificant (P = .5). This novel method can offer advantages which are as follows: being more accurate than the dye alone, saving operative time, abandoning complex logistic preparations for the radioisotope, and solving the problem of timing.

Feasibility of early postoperative bladder catheter removal without prior bladder-training exercises after laparoscopic nerve sparing radical hysterectomy.

The aim of the study is to evaluate the feasibility of early postoperative bladder catheter removal without prior bladder-training exercises after laparoscopic nerve sparing radical hysterectomy (LNSRH). The post-operative bladder catheterisation period of 30 patients who underwent LNSRH at two institutes in Egypt and Italy were prospectively evaluated with postoperative drainage of the bladder through a Foley catheter for two days without performing bladder-training exercise. The median duration for postoperative bladder catheterisation was 3.5 (3-5) days. Within the fifth postoperative day, 82.7% had a PVR urine volume less than 100 ml. None of the patients had PVR urine more than 100 ml more than 10 days after the operation with no need for self-catheterisation. These results support early postoperative bladder catheter removal without prior bladder-training exercises following LNSRH. IMPACT STATEMENT What is already known on this subject? Bladder-training exercise was used routinely following radical hysterectomy (RH) operations before bladder catheter removal. Only two studies reported that these exercises could be omitted, but one study was done on both laparoscopic and open RH patients and the other did not show whether the operation was nerve-sparing and whether it was done by laparoscopy or open technique. What the results of this study add? This study's results support early postoperative bladder catheter removal without prior bladder-training exercises after laparoscopic nerve sparing RH. What the implications are of these findings for clinical practice and/or further research? Excluding the unnecessary procedure of bladder training, which is time- and effort-consuming, after the operation.

Male Breast Huge Malignant Phyllodes.

Introduction: Phyllodes tumors are rare breast tumors. The best treatment is wide local excision with 1 cm safety margin unless metastatic. The three pathological types (benign, borderline and malignant were reported in men. Case presentation: A 73year-old male with huge left breast swelling extending from the clavicle to the left hypochondriac region. Core needle biopsy suggested malignant phyllodes tumor. Postcontrast CT revealed a huge mass seen at the left anterolateral chest wall measuring about (22 x 25 x 26 cm). Simple mastectomy was performed en bloc with the tumor. The microscopic examination led to the diagnosis of high grade malignant phyllodes. IHC showed diffuse positive vimentin, CD10 and negative CK in the neoplastic cells. The patient lost follow up for three months.Then he was presented with fungating local recurrence with bilateral metastatic pulmonary. The patient underwent palliative excision. After the second surgery, he was prepared for palliative chemoradiotherapy but the patient died one month later at home. Discussion and conclusions: Very few cases of phyllodes tumor were reported in men. Pathologically, phyllodes tumors are subdivided into three types: benign, borderline and malignant according to mitotic frequency, nature of margins, stromal growth, cellularity and atypia. Malignant phyllodes tumors tend to spread via hematological route mainly to the lung, then to the bone. Phyllodes tumors even benign type tend to recur even after complete excision with higher tendency for malignant cases. Wide local excision is the standard of care for phyllodes tumors with or without adjuvant radiotherapy in malignant lesions- with no proved value for chemotherapy or hormonal therapy.

The outcome of oncoplastic techniques in defect reconstruction after resection of central breast tumors.

BACKGROUND: Traditionally, conservative breast surgery was contraindicated in centrally located breast tumors, with total mastectomy as the treatment of choice. However, restorations of the central defects by the oncoplastic volume displacement or replacement techniques have been shown to be effective. The aim of the current study was to assess the surgical outcome of oncoplastic techniques after central breast tumors resection. METHODS: Thirty patients with central breast cancer, including two patients with Paget disease, treated at the Oncology Center of Mansoura University (Egypt) between June 2011 and December 2014 were included in this study. The oncoplastic techniques performed were Grisotti advancement rotational flap in eight (26.7%) patients, classic skin-sparing mastectomy (SSM) with latissimus dorsi pedicled flap in 20 (66.7%) patients, and skin-reducing mastectomy (SRM) with latissimus dorsi pedicled flap using wise pattern inverted T incision in two (6.7%) patients. The choice of the oncoplastic techniques depends on the achievement of free safety margins, the breast volume, and its ptotic degree. RESULTS: The median age was 40.5 years (range; 23-55). There were no major complications that require repeating the oncoplastic techniques. Recorded complications included wound dehiscence (4/30, 13.3%) donor site seroma (4/30, 13.3%), and surgical site infection (1/30, 3.3%). The 6-month subjective patient satisfaction was excellent in 21 (70%) patients, good in 6 (20%) patients, and fair in 3 (10%) patients. There was no episode of local recurrence or systemic metastasis after an average follow-up duration of 24 months (range; 6-42). CONCLUSIONS: Restoring the central defect after resection of the central breast tumors can be safely achieved using oncoplastic procedures including the Grisotti technique or the design of SSM or SRM with immediate breast reconstruction. In our patients, these procedures yield a satisfactory esthetic outcome with lower morbidity.

A retrospective analysis of survival and prognostic factors of male breast cancer from a single center.

BACKGROUND: Less than 1% of all breast cancer cases are found in men, who reportedly have inferior outcomes compared with matched women patients. Ethnic differences may also affect their prognosis. Here, we investigated overall survival (OS) and major prognostic factors for male breast cancer (MBC) in a cohort of Egyptian patients. METHODS: We retrospectively analyzed OS in a cohort of 69 male patients with MBC who were surgically treated at the Mansoura Cancer Center, Egypt between 2000 and 2007. We registered demographic data, age, height, weight and body mass index, tumor size, histology, number of infiltrated axillary lymph nodes, hormone receptor (HR) status and metastatic presence, and TNM staging. Patients' OS was the primary endpoint. Patients received treatment to the medical standards at the time of their diagnosis. RESULTS: In the 69 patients who met the inclusion criteria and had complete stored patient data, tumors ranged from T1c to T3. We could gather cancer-related survival data from only 56 patients. The collective 5-year survival in this cohort was 46.4%. Only five patients had distant metastasis at diagnosis, but they showed a null percent 5-year survival, whereas those with no lymph node infiltration showed a 100% 5-year survival. Lymph node status and tumor grading were the only prognostic factors that significantly affected OS. CONCLUSIONS: Lymph node status and tumor grade are the most important prognostic factors for overall survival of MBC in Egyptian male patients; whereas even remarkably low HR expression in MBC did not significantly affect OS. Further research is needed to understand the factors that affect this disease.

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

BACKGROUND: The aim of this study is to define an algorithm for the choice of reconstructive method for defects after laryngo-pharyngo-esophagectomy for hypopharyngeal carcinoma. METHODS: One 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. RESULTS: Pectoralis 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). CONCLUSION: Free 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.

Computed Tomographic Angiography in Planning Thoraco-dorsal Artery Perforator Flap in Breast and Soft Tissue Reconstruction: A Systematic Review.

OBJECTIVES: Thoraco-dorsal Artery Perforator (TDAP) flaps have been increasingly used in breast and soft tissue reconstruction. Perforator localization is often done using a hand-held doppler, however, false results are not uncommon. This study aimed to systematically review the literature on the value of preoperative Computed Tomographic Angiography (CTA) in TDAP flaps examining scanning protocol, mapping technique, concordance with operative findings and disadvantages. METHODS: A PRISMA-compliant comprehensive search of Medline, Embase, Cochrane Library and CINAHL databases was conducted in November 2023. We included studies evaluating CTA mapping of free and pedicled TDAPs for breast or soft tissue reconstruction using The Joanna Briggs Institute (JBI) Critical Appraisal Tools. RESULTS: Five studies were included and considered at high risk of bias. The studies included 72 patients with a mean age of 43.8 years. Concordance between CT findings and Doppler mapping or operative visualization was reported in two studies. In three studies, CTA was combined with Doppler flowmetry, whilst dynamic infrared thermography was used in one study. Standardized scanning protocol and patient positioning were lacking in all reports. CONCLUSIONS: This study highlights the paucity of evidence on the value of CTA in TDA perforator mapping with inconsistent outcomes and non-standardized scanning protocols. Despite difficult imaging acquisition and interpretation, 3D reconstructed images and detailed vascular anatomy may facilitate planning. ADVANCES IN KNOWLEDGE: Further research is required to explore the practical value of CTA in TDAP planning and standardizing protocols.

Quality of life among Egyptian women with breast cancer after sparing mastectomy and immediate autologous breast reconstruction: a comparative study.

Breast reconstruction is considered as an integrated part of the modern breast surgery. The aim of this study is to evaluate whether immediate autologous breast reconstruction influences QOL and patient satisfaction outcomes among Egyptian women with breast cancer in comparison to the traditional mastectomy. This is a prospective study in which 200 Egyptian women with non metastatic breast cancer were included; group I (100 patients) underwent sparing mastectomy with immediate autologous breast reconstruction and group II (100 patients) underwent traditional mastectomy. The patient satisfaction with breast reconstruction was evaluated by special questionnaire and the reasons given by traditional mastectomy patients for not having breast reconstruction were recorded. Both breast impact of treatment scale (BITS) and body satisfaction scale (BSS) were evaluated in both groups. Patient satisfaction with breast reconstruction had a high mean score of 14.44 out of total degrees of 20 and most of them voted yes for having the same reconstruction again if they were offered it and would recommend reconstruction to other patients. No difference was found between the two groups as regard the BITS score. However, the BSS score showed a higher score among the reconstruction group. Egyptian ladies with breast cancer show better QOL and body image satisfaction outcomes following immediate breast reconstruction.

Pectoralis major myo-parenchymal flap for local reconstruction of partial mastectomy defects: Description of a new technique.

INTRODUCTION: Breast conservation is the standard of care for early breast cancer. Several oncoplastic approaches have been described for the reconstruction of partial breast defects. The multiplicity of techniques indicates that the ideal reconstructive technique is yet to be identified. There has been a recent emphasis on minimizing the magnitude of surgery. In this report, we describe our experience using the pectoralis major muscle to fill relatively large post-tumorectomy breast defects. PATIENTS AND TECHNIQUE: Nine patients were operated on for malignant breast lesions. Tumorectomy resection with surgical margin rendered a 40-50% breast defect. The parenchymal defect was repaired with an advancement muscle flap of the ipsilateral pectoralis major muscle. RESULTS: All patients experienced a non-eventful postoperative course. The early cosmetic outcome was excellent in four patients, good in another four, and fair in one patient. CONCLUSION: The pectoralis major flap is useful for local repair of upper half partial breast defects in non-ptosed, cup A-B breasts.

Continent catheterizable umbilical low-pressure intestinal pouch with split ileal end seromuscular anti-reflux technique.

BACKGROUND: Cosmesis, better function, and stomal stricture avoidance are important issues in constructing continent urinary abdominal stomas for bladder cancer patients when orthotopic urinary diversion is not feasible. This study aims to evaluate the outcome of continent catheterizable umbilical low-pressure intestinal pouch incorporating a new split ileal end anti-reflux technique. METHODS: Twenty-three patients underwent a continent umbilical low-pressure intestinal pouch incorporating a new seromuscular antireflux technique (split ileal end) after radical cystectomy when orthotopic reconstruction was not feasible. Mean operative time was 210 min (130 min for radical cystectomy and 80 min for reconstruction of the pouch). The mean follow-up after surgery was 18 mo (range 6-30 mo). RESULTS: The most common early postoperative complications were urinary leak that occurred in nine patients: seven were conservatively managed and two by re-exploration. Late postoperative complications occurred in eight patients, of whom three developed stomal stenosis and treated successfully with repeated dilatation. Thirteen patients were totally continent, seven were fairly continent, and only two were poorly continent. CONCLUSIONS: The functional results with this catheterizable umbilical low pressure intestinal pouch incorporating our new anti-reflux technique were satisfactory with better cosmesis.

Levator anguli oris muscle based flaps for nasal reconstruction following resection of nasal skin tumours.

BACKGROUND: surgical excision remains the best tool for management of skin tumors affecting nasal skin, however many surgical techniques have been used for reconstruction of the nasal defects caused by excisional surgery. The aim of this work is the evaluation of the feasibility and outcome of levator anguli oris muscle based flaps. METHODS: Ninety patients of malignant nasal skin tumours were included in this study. Age was ranged from four to 78 years. For small unilateral defects affecting only one side ala nasi, levator anguli oris myocautaneous (LAOMC) flap was used in 45 patients. For unilateral compound loss of skin and mucus membrane, levator anguli oris myocautaneous mucosal (LAOMCM) flap was used in 23 patients. Very large defects; bilateral either LAOMC or LAOMCM flaps combined with forehead glabellar flaps were used to reconstruct the defect in 22 patients. RESULTS: Wound dehiscence was the commonest complication. Minor complications, in the form of haematoma and minor flap loss were managed conservatively. Partial flap loss was encountered in 6 patients with relatively larger tumours or diabetic co-morbidity, three of whom were required operative re-intervention in the form of debridement and flap refashioning, while total flap loss was not occurred at all. CONCLUSIONS: Immediate nasal reconstruction for nasal skin and mucosal tumours with levator anguli oris muscle based flaps (LAOMC, LAOMCM) is feasible and spares the patient the psychic trauma due to organ loss.

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

BACKGROUND: Reconstruction of large scalp defects after tumor resection is a challenging problem. We aimed at putting an algorithm for reconstruction of those defects. METHODS: Forty-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. RESULTS: No peri-operative mortality was encountered. Usage of free flaps was superior in cosmoses and function with an acceptable rate of complications. CONCLUSION: for scalp defects wider than 100 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.

Sentinel lymph node biopsy in breast cancer guided by CT lymphography; History, evolution and current applications.

Sentinel lymph node biopsy (SLNB) has efficiently replaced axillary lymph node dissection (ALND) in axillary staging in node-negative breast cancer patients. Dual sentinel lymph node (SLN) localization using radioisotopes and blue dye is the standard technique for SLN mapping. Yet, nuclear medicine facilities are not widely available worldwide. In Japan, Computed tomography lymphography (CTLG) is presented as an SLN mapping technique which was first suggested in 2003 by Suga et al. Multiple subsequent studies confirmed the efficacy of CTLG in SLN mapping in breast cancer. Further applications of the technique followed; such as prediction of SLN metastasis using CTLG, the use of CTLG guided SLN biopsy after neoadjuvant therapy, video-assisted CTLG guided SLN biopsy, the use of real-time virtual sonography with 3-D CTLG, and preoperative localization of the CTLG mapped SLN using either real-time virtual sonography (RVS) guided Indocyanine green (ICG) injection or its marking using liquid charcoal and silver wire and the use of SPIO enhanced magnetic resonance imaging (MRI) for prediction of metastasis in SLNs detected by CTLG. This efficacy and variable applications open the door for conducting wide-scale randomized controlled trials to suggest using CTLG as an efficient alternative for the use of radioisotopes in SLN mapping in breast cancer patients, especially in low and middle-income countries.

Alterations of PTEN and SMAD4 methylation in diagnosis of breast cancer: implications of methyl II PCR assay.

BACKGROUND: Diagnosis of breast cancer is more complicated due to lack of minimal invasive biomarker with sufficient precision. DNA methylation is a promising marker for cancer diagnosis. In this study, authors evaluated methylation patterns for PTEN and SMAD4 in blood samples using EpiTect Methyl II QPCR assay quantitative PCR technology. RESULTS: Methylation status for PTEN and SMAD4 were statistically significant as breast cancer patients reported hypermethylation compared to benign and control groups (77.1 ± 17.9 vs. 24.9 ± 4.5 and 15.1 ± 1.4 and 70.1 ± 14.4 vs. 28.2 ± 0.61 and 29.5 ± 3.6, respectively). ROC curve analysis revealed that both PTEN (AUC = 0.992) and SMAD4 (AUC = 0.853) had good discriminative power for differentiating BC from all non-cancer individuals (benign and healthy combined) compared to routine tumor markers CEA (AUC = 0.538) and CA15.3 (AUC = 0.686). High PTEN methylation degree was associated with late stages (84.2 ± 17.4), positive lymph node (84.2 ± 18.5), positive ER (81.3 ± 19.7), positive PgR (79.5 ± 19.1), and positive HER2 (80.7 ± 19.0) vs. 67.4 ± 13.8, 70.6 ± 14.8, 72.8 ± 14.9, 72.5 ± 14.7, and 70.2 ± 13.5 in early stages, negative lymph node, negative ER, negative PgR, and negative HER2, respectively. Similar results were obtained regarding SMAD4 methylation. Sensitivity, specificity, positive and negative predictive values, and accuracy for methylated PTEN were 100%, 95%, 99.1%, 100%, and 95%, respectively when differentiated BC from all-non cancer controls. Interestingly, PTEN could distinguish early BC stages with good sensitivity 84.4%, 51.4%, 69.1%, 72%, and 70%, respectively. CONCLUSION: Methylation status of PTEN and SMAD4 is a promising blood marker for early detection of breast cancer. Future studies are needed for their role as prognostic markers.

Invasive ductal carcinoma: correlation of apparent diffusion coefficient value with pathological prognostic factors.

The aim of this study was to correlate the apparent diffusion coefficient (ADC) value of invasive ductal carcinoma with pathological prognostic factors. A prospective study was conducted on 59 untreated female patients (mean age 46 years) with invasive ductal carcinoma. All patients were examined at 1.5 Tesla using dedicated bilateral breast coil. They underwent diffusion weighted MR imaging of the breast using a single shot echo planar imaging with a b-factor of 200 and 400 sec/mm2. Apparent diffusion coefficient (ADC) maps were reconstructed. The ADC value of the breast cancer was calculated and correlated with the pathologic prognostic factors (tumor size, grade and lymph nodes). The mean ADC values of invasive ductal carcinoma were significantly lower in patients with high grade, large breast cancer as well as those with axillary lymph nodes metastasis in a statistically significant way (p = 0.001 for the three factors). The mean ADC value of invasive ductal carcinoma was correlated with histologic grade (r = -0.675, p = 0.001), tumor size (r = 0.504, p = 0.001) and showed lower ADC values with positive lymph node metastasis. Apparent diffusion coefficient value is correlated with pathological parameters of invasive ductal carcinoma. The lower ADC values are associated with higher histological grade, larger tumor size and presence of axillary lymph nodes. So, the ADC value can be considered as a promising prognostic parameter that may identify highly aggressive breast cancer.

Cost-effectiveness of clinical breast assessment-based screening in rural Egypt.

INTRODUCTION: Breast cancer is the most common cancer in Egyptian women. However, the mean tumor size at diagnosis is 4.5 cm, and the median age is approximately 46 years. Both of these factors decrease the utility and cost-effectiveness of a mammography-based screening program typically designed for developed countries. We report the first clinical breast assessment-based screening project in an entirely rural Egyptian community. METHODS: Targeted population: Women aged 25-65 years in three municipal regions of Dakahlia province, Egypt. The estimated targeted population was 57,500 and participation was voluntary. First stage was performed at primary health care points. Surgeons performed systematic clinical breast examination. All data were collected at Mansoura University. Abnormal findings in the primary examination led to an invitation to the Oncology Center--Mansoura University--where the second stage of the study took place. It comprised repeat examination, ultrasonography, and/or mammography. Therapeutic interventions were performed at the governmentally funded Mansoura Oncology Center. RESULTS: Voluntary participation reached 10.2% of the target group and abnormal clinical examination represented 3.2% (191/5,900). The screen-detected cancers were (18/5,900) of examined population, and thus the cancer detection rate of clinical breast assessment-based screening was 30.5 per 100,000 of participating women during 2 years. The tumor size was 1.5 cm (median) and 1.3 cm (mean). The cost of screening per cancer case detected was approximately 415 US$, and the overall cost of treating a screen-detected cancer was 1,015-1,215 US$. CONCLUSIONS: Clinical breast assessment-based screening with selective mammography is an effective modality, which improves the results of breast cancer management in Egypt.

The role and limitations of mammary ductoscope in management of pathologic nipple discharge.

Mammary ductoscope allows visualization of the breast ductal wall and sampling of the abnormal area for diagnostic purposes. We are reporting our center experience in application of mammary ductoscope in detecting the underlying etiology of pathologic nipple discharge. Between November 2005 and December 2006 a total of 54 women, with spontaneous persistent nonlactational unilateral uniductal nipple discharge of no palpable lesions and negative breast sono-mammography, were included in the study for morphologic assessment of ductal epithelium, ductal lavage and ductoscopically guided procedures as punch biopsy and ductoscopically guided microdochectomy. Forty-one patients (76%) with nipple discharge were positive ductoscopically. Thirteen patients (24%) appeared normal. Ductoscopic lavage has a much more cellular yield than ordinary squeezing cytology. Ductal thickening by the ductoscope (11 cases) revealed to be hyperplasia on pathology (five cases), papilloma (two cases), atypical ductal hyperplasia (two cases), ductal carcinoma in situ (one case), and invasive breast carcinoma (one case). There was a significant association between intraductal visual observations and histopathologic diagnosis. Mammary Ductoscope is a promising tool in management of pathologic nipple discharge. Biopsy and ablation techniques can be performed during ductoscopy with correlation between visual findings and histopathology, but there are still some limitations of in clinical practice.

Complete Mesocolic Excision With Central Vascular Ligation in Comparison With Conventional Surgery for Patients With Colon Cancer - The Experiences at Two Centers.

PURPOSE: Revolutions have occurred over the last 3 decades in the management of patients with colorectal cancer. Most advances were in rectal cancer surgery, especially after the introduction of the total mesorectal excision (TME) by Heald. However, no parallel advances regarding colon cancer surgeries have occurred. In 2009, Hohenberger introduced a new concept trying to translate the survival advantages of TME to patients with colon cancer. This relatively new concept of a complete mesocolic excision (CME) with central vascular ligation (CVL) in the management of patients with colon cancer represents an evolution in operative technique. We performed a comparative study between CME with CVL and conventional surgery for patients with colon cancer at Italian and Egyptian cancer centers, considering surgical quality and clinical outcome. METHODS: Seventy-nine Egyptian patients underwent conventional surgery (non-CME group) while 52 Italian patients underwent CME with sharp dissection between the embryological planes and CVL of the supplying vessels (CME group). RESULTS: Significantly better results were observed in terms of lymph node yield (CME group: 22.5 vs. non-CME group: 12; P < 0.0001) and lymph node ratio (CME group: 0.03 vs. non-CME group: 0.22; P < 0.0001). Regarding surgical morbidity, no significant difference was noted (CME group: 2 vs. non-CME group: 5; P < 0.702). CONCLUSION: CME appears to be a safe procedure when performed by experienced hands through proper embryological planes. It also provides a superior specimen, with a higher lymph node yield, which consequently affects the lymph node ratio. Eventually, CME with CVL should be increasingly adopted and studied more deeply.

Propensity score-matched comparison between complete mesocolic excision and classic right hemicolectomy for colon cancer.

BACKGROUND: The prognosis of right colon cancer remains disappointing. Complete mesocolic excision (CME) with central vascular ligation (CVL), based on the same oncological principles of total mesorectal excision, has been speculated to result in a better outcome. To evaluate the oncological adequacy of CME with CVL, we carried out a comparative study with propensity score-matched analysis between two different surgical procedures performed at Italian and Egyptian University cancer centers. METHODS: Forty-six Egyptian patients underwent conventional right hemicolectomy, while eighty-eight Italian patients underwent CME with sharp dissection between the embryological planes, exposure of the superior mesenteric vessels with extended lymphadenectomy, and CVL. RESULTS: All operations were successful with no increase in postoperative complications (10% in the patients undergoing CME vs. 19.5% in Egyptian patients). Number of harvested nodes (21 vs. 13) and lymph node ratio (0.08 vs. 0.22) were significantly different in patients undergoing CME (P=0.0001 and P=0.005, respectively). In these patients, the risk of cancer relapse was reduced to as much as one third (8% vs. 22%), even in node-positive tumors, and locoregional recurrences were never experienced. The classic operation was significantly associated with poor outcome (5-year disease-free survival rates were 89.2% in the group undergoing CME and 49.1% in the classic group, P=0.02). Propensity score-matched analysis warranted optimal balance and confirmed overall results. CONCLUSIONS: Right colon cancer patients undergoing CME benefitted from more oncological adequacy, with no increased postoperative complication rate, a decreased locoregional recurrence rate, and a better long-term outcome than patients operated on with the conventional procedure.

Parotid Quadrantectomy Is a Safe Management for Localized Pleomorphic Adenoma.

AIM: Pleomorphic adenoma is the most common benign tumor of the parotid gland and is classically treated with superficial or total parotidectomy. Less radical surgeries have been proposed to minimize the risk of facial nerve injury. The oncological safety of these procedures remains controversial. We conducted this study to evaluate the safety of superficial hemi-lobectomy (quadrantectomy). PATIENTS AND METHODS: Retrospective analysis was conducted on the paraffin sections of archived superficial parotidectomy specimens from 11 male and 6 female patients (median age 33 years). The microscopic extent of extra-capsular extension was determined on pathological revision. In addition, prospective evaluation of 12 quadrantectomy procedures (M/F = 7/5, median age = 36 years) compared to 24 radical surgeries (M = F, median age = 40 years) regarding temporary and persistent facial nerve dysfunction on routine clinical assessment and recurrence rate. RESULTS: On retrospective pathological revision, pleomorphic adenomata had a median microscopic spread of 3 mm beyond capsule in paraffin sections (SD = 3.6). On prospective analysis with a median follow-up of 33 months (range = 18-54 months), quadrantectomy had similar relative risk of temporary facial nerve dysfunction evaluated at the immediate postoperative period as well as persistent nerve dysfunction assessed at 3 months (P = 0.701 and P = 0.902, respectively). Of the whole study population, one case of recurrence after total parotidectomy was observed at mid-term follow-up (P = 1.000). CONCLUSION: Parotid quadrantectomy is a safe management for smaller pleomorphic adenomata localized close to one of the two divisions of the facial nerve.
