Prognosis of recurrent laryngeal carcinoma after laryngectomy

Background. Recurrence is common after total laryngectomy for advanced laryngeal carcinoma. The aim of the present study was to review the prognosis of recurrent laryngeal carcinoma after total laryngectomy. Methods. The records of 165 patients who developed recurrences after total laryngectomy for laryngeal squamous cell carcinoma between January 1971 and December 1990 were reviewed. Results. Of the 165 patients who developed recurrences, 34 (21%) patients had surgical salvage. The sites of recurrence of these 34 operable patients included 11 pharyngeal, 3 tracheostomal, 15 nodal, 2 pharyngeal with nodal, and 3 pulmonary metastasis. Pharyngeal recurrence had the highest salvage rate, followed by nodal and pulmonary recurrence. All patients with tracheostomal had recurrence after salvage surgery. After the surgical salvage, the tumor recurrence rate was 44% and the 5-year actuarial survival rate was 42%. Of the other 131 patients who had palliative treatment without surgical salvage, the 5-year actuarial survival rate was 2%. Conclusions. The present study showed that patients who had surgical salvage for recurrent tumor after total laryngectomy had satisfactory prognosis. Close follow-up of patients after initial operation is essential to detect recurrence early, while surgical salvage is still feasible.     

Conservation laryngeal surgery versus total laryngectomy for radiation failure in laryngeal cancer

BACKGROUND: Total laryngectomy is the standard of care for surgical salvage of radiation failure in laryngeal cancer. However, the role of conservation laryngeal surgery in this setting remains unclear. The objective was to compare the efficacy of conservation versus total laryngectomy for salvage of radiation failure in patients who initially presented with T1 or T2 squamous cancer of the larynx. METHODS: A 21-year retrospective analysis of patients who received surgery at a single comprehensive cancer center after definitive radiation therapy is reported. At recurrence, the patients were reevaluated and then underwent a total laryngectomy or, if possible, a conservation laryngeal procedure. The charts of 105 patients who failed radiation treatment for primary laryngeal cancer and who subsequently underwent surgical salvage were reviewed for this study. Eighty-nine were male (84.8%). The mean age was 60.3 years. The median follow-up time after surgery was 69.4 months. Most patients with recurrence after radiotherapy required total laryngectomy (69.5%; 73/105). Conservation laryngeal surgery was performed for 32 patients (31.5%). Concomitant neck dissections were performed on 45 patients (45.5%). RESULTS: In 14 patients, local or regional recurrence developed after salvage surgery: 9 patients after total laryngectomy (12.3%; 9/73), and 5 patients (15.6%; 5/32) after conservation laryngeal surgery. This difference was not statistically significant, nor was there a difference in disease-free interval for the two procedures (p = .634, by log-rank test). Distant metastasis developed in 13 patients. Most developed in the setting of local and/or regional recurrence, but distant metastasis occurred as the only site of failure in 6 of the patients who had undergone total laryngectomy but in 1 of the conservation surgery patients treated for a supraglottic laryngeal cancer. The overall mortality for patients who underwent total laryngectomy was also higher: 73.74% (54/73) versus 59.4% (19/32) for patients who underwent a conservation approach (p = .011 by log-rank test). CONCLUSIONS: Although conservation laryngeal surgery was possible in a few patients with local failure after radiotherapy, conservation laryngeal surgery is an oncologically sound alternative to total laryngectomy for these patients.     

Videofiberoptic examination of the pharyngoesophageal segment and esophagus in patients after total laryngectomy

BACKGROUND: Posttreatment follow-up in patients with squamous cell carcinoma of the head and neck is critical because of the high risk of recurrence or a new primary tumor. However, in patients who have undergone total laryngectomy, evaluation of the pharyngoesophageal segment (PES) and esophagus is difficult. METHODS: Sixty patients who had undergone total laryngectomy received a videofiberoptic examination of the PES and esophagus at the OPD office during follow-up. RESULTS: Satisfactory examination was achieved in 56 (93%) of the patients. Each procedure was completed within 15 minutes. Although only 11 (18%) of the patients were symptomatic at follow-up, 19 patients (34%) had significant findings, including one local recurrence and two secondary esophageal cancers. Patients were asymptomatic in all three cases. CONCLUSIONS: Videofiberoptic examination is a simple, effective, and relatively noninvasive method that can be performed in the OPD office to evaluate the PES and esophagus in patients after total laryngectomy.     

Stomal recurrence after total laryngectomy for squamous cell carcinoma of the larynx.

OBJECTIVE: Stomal recurrence after total laryngectomy is one of the most serious issues in the management of laryngeal carcinoma. The management of stomal recurrence, including chemotherapy, radiotherapy, and surgery, has been reported as unsatisfactory. STUDY DESIGN AND SETTING: From 1985 to 1995, 69 patients underwent total laryngectomy for the treatment of laryngeal cancer at the University of Tokyo Hospital. To identify the risk factors for stomal recurrence, we analyzed these patients according to various clinicopathological factors. RESULTS: Stomal recurrence developed in 6 of 69 patients who underwent total laryngectomy for laryngeal carcinoma. Statistical analysis reveals that primary site, preoperative tracheotomy, and paratracheal lymph node metastasis are significant risk factors for stomal recurrence. CONCLUSION: Intensive follow-up should be performed for patients with glottic carcinoma who had preoperative tracheotomy, paratracheal lymph node metastasis, or both to detect stomal recurrence at an early stage.     

Outcome after partial frontolateral laryngectomy

The purpose of this study was to determine the recurrence rate and the long-term survival of patients treated with frontolateral laryngectomy for early glottic cancer. The study is a retrospective analysis of a cohort of patients who underwent frontolateral laryngectomy from 1995 to 2002 with a median follow-up of 48 months. This was a consecutive series of 30 patients with T1bN0 and T2N0 vocal fold carcinoma. Previously treated patients were excluded. Surgical treatment consisted of frontolateral partial vertical laryngectomy and reconstruction with bipedicle sternohyoid muscle flap. Twenty-five patients have been alive with no evidence of the disease. The median follow-up was 48 months (range, 6-85 months). Five patients experienced local recurrence. One of them underwent salvage partial hemilaryngectomy, and 4 underwent wide-field total laryngectomy with adjuvant postoperative radiation therapy. Four of five patients with retreatment were ultimately salvaged, with a median follow-up of 30 months. We had one death caused by the disease. Frontolateral laryngectomy is an efficient treatment for selected cases of early glottic carcinoma.     

A nine-year institutional experience with near-total laryngectomy

BACKGROUND: Pearson's near-total laryngectomy (NTL) is an alternative procedure to total laryngectomy in selected patients with advanced laryngeal cancer. Based on our experience with NTL for >9 years, we present here the functional results, complications, and survival rates. METHODS: A retrospective study was carried out from January 1993 to May 2002. We studied 15 patients with advanced laryngeal, oropharyngeal, and hypopharyngeal cancer who underwent NTL. Survival rates were calculated using the Kaplan-Meier method. RESULTS: The most common complication was fistula (8 of 15) followed by minor aspiration (4 of 15 patients). Eleven patients (73.5%) attained a good voice; 3 patients (19.9%) obtained a bad voice; and 1 did not achieved vocal ability. Three patients (19.9%) had local recurrence; no patients had neck recurrence; and 2 patients (13.3%) had distant metastasis. Six patients (40%) died from their disease, and 2 (13.3%) patients died from other causes. The 3-year actuarial survival rate was 81.6%. CONCLUSIONS: NTL is useful in the treatment of selected patients with advanced laryngeal, oropharyngeal, and hypopharyngeal cancer and results in good control and survival rates. Satisfactory functional results can be attained in the majority of patients. When the surgical margins are positive or close, TL must be carried out.     

Long-term follow-up of cartilaginous tumors of the larynx.

BACKGROUND: Cartilaginous tumors of the larynx are uncommon. A literature review disclosed approximately 250 cases since 1816; the cricoid cartilage is the most common site. The rarity of these tumors has made for limited experience and, as a consequence, our knowledge is incomplete. OBJECTIVE: To report surgical results as well as long-term follow-up on 6 patients with cartilaginous tumors of the larynx. DESIGN: A 28-year retrospective study with the patients followed-up from 6 to 28 years (average, 17.8 years). METHODS: Six adult white male patients with cartilaginous tumors of the larynx: 4 low-grade chondrosarcoma (1 of the thyroid and 3 of the cricoid) and 2 chondroma of the cricoid. Surgical treatment included total laryngectomy of the thyroid and 1 of the cricoid chondrosarcoma, and conservation surgery of the other 4 cricoid tumors: the 2 patients with chondrosarcoma had total resection of the cricoid cartilage with thyrotracheal anastomosis, and the 2 patients with chondroma had local tumor resection using a laryngofissure approach. RESULTS: The margins of the specimen were negative for tumor in the 6 patients. On follow-up, none of the patients had regional or distant metastasis or tumor-related death. One of the patients with cricoid chondrosarcoma developed recurrence 8 years after conservation surgery, and required a total laryngectomy for salvage. Survival rate tumor-free at 5 years was 100% and at 10 years 67%, co-morbidity being responsible for the decrease in survival rate. CONCLUSIONS: Based on this small series of patients, the long-term follow-up of benign and low-grade malignant tumors suggests that the surgical approach and prognosis does not depend on histologic distinction and, importantly, underdiagnosed malignancy on tumor sampling and recurrent chondrosarcoma, managed with salvage surgery, have no adverse impact on patient survival. Total resection of the cricoid cartilage with thyrotracheal anastomosis over a stent proved an alternative surgical technique in chondrosarcoma who otherwise would have been treated by total laryngectomy.     

Screening for local and regional cancer recurrence in patients curatively treated for laryngeal cancer: definition of a high-risk group and estimation of the lead time

BACKGROUND: All patients treated for laryngeal cancer are offered the same follow-up schedule to detect asymptomatic locoregional recurrences. In this study, we evaluated the prognostic profile of patients for cancer recurrence and estimated the lead time. METHODS: A cohort study was performed between 1990 and 1995. Cox proportional hazards model was used to analyze the prognostic factors. The effect of altering the follow-up for asymptomatic recurrence detection was determined after estimating the lead time. RESULTS: The variables cT classification, smoking, and histologic grade proved to be prognostic factors. The risk of locoregional failure was 15% in the low-risk group versus 29% in the high-risk group. The estimated lead time was 2 to 4 weeks. CONCLUSION: Risk profiles for locoregional relapse were defined. Intensifying the follow-up schedule is not advisable because the lead time is very short. An excessively high number of routine visits would have to be performed to increase the detection rate for asymptomatic recurrences.     

Clinical outcome following total laryngectomy for cancer

Background: Patients with advanced cancers of the larynx and hypopharynx have been treated with total laryngectomy at the Department of Head and Neck Surgery, Royal Prince Alfred Hospital, Sydney in the past. Increasingly, these patients are being managed with organ‐sparing protocols using chemo­therapy and radiotherapy. The aim of the present study was to review complication, recurrence and survival rates following total laryngectomy. Methods: Patients who had total laryngectomy for squamous carcinomas of the larynx or hypopharynx between 1987 and 1998 and whose clinicopathological data had been prospectively accessioned onto the computerized database of the Department of Head and Neck Surgery, Royal Prince Alfred Hospital, were reviewed. Patients whose laryngectomy was a salvage procedure for failed previous treatment were included. Results: A total of 147 patients met the inclusion criteria for the study, including 128 men and 19 women with a median age of 63 years. Primary cancers involved the larynx in 90 patients and hypopharynx in 57. There were 30 patients who had recurrent (n = 24) or persistent disease (n = 6) after previous treatment with radiotherapy (26 larynx cases and four hypopharynx cases). Pharyngo‐cutaneous fistulas occurred in 26 cases (17.7%) and, using multivariate analysis, the incidence did not correlate with T stage, previous treatment or concomitant neck dissection. Local control rates were 86% for the larynx and 77% for the hypo­pharynx groups and neck control was 84% and 75%, respectively. Five‐year survival for the larynx cancer group was 67% and this was significantly influenced by T stage and clinical and pathological N stage. Survival in the hypopharynx group was 37% at 5 years and this did not significantly correlate with T or N stage. There was a non‐significant trend to improved survival among previously treated patients whose laryngectomy was a salvage procedure. Conclusion: Patients with cancer of the larynx had a significantly better survival following total laryngectomy than patients with hypopharyngeal cancer. Those whose laryngectomy was carried out as a salvage procedure following failed previous treatment did not have a worse outcome than previously untreated patients.     

Supracricoid laryngectomy with CHEP: functional results and outcome.

OBJECTIVES: To assess whether supracricoid laryngectomy with cricohiodoepiglottopexy could successfully reach the cure and preserve the voice in glottic laryngeal cancer, we studied 27 patients with T2/T3 squamous cell carcinoma of the larynx treated in our institution with cricohiodoepiglottopexy. STUDY DESIGN: A retrospective analysis has been carried out between 1995 through 1997. We classified 11 patients as T2N0M0 and 16 patients as T3N0M0. Nineteen patients had bilateral selective lateral neck dissection, 3 patients had unilateral lateral neck dissection, and 5 patients had undissected neck. Survival was analyzed under the Kaplan-Meyer method. RESULTS: Five patients had postoperative complications, 2 were treated with a total laryngectomy. The remaining 25 patients kept the normal airway, swallowing, and speech. None of the patients in the neck dissection group had neck metastasis. Two patients had recurrences, 1 with local recurrence was treated with a total laryngectomy and is alive without disease; the other patient had neck recurrence, was treated with radical neck dissection plus radiotherapy, and is dead of the disease. One patient had a second tumor in oropharynx treated with palliative radiotherapy and is dead of the disease. Three years disease-free survival was 75% for T2 and 79% for T3. CONCLUSIONS: This technique is useful in the treatment of selected cases of T3/T2 glottic cancer regarding the extent of disease. The incidence of complications in need of a complete laryngectomy does not compromise the functionality of this technique. The survival is comparable to patients who submitted to total laryngectomy and near-total laryngectomy, regarding the extent of the lesion.     

Changes in treatment of advanced laryngeal cancer 1985-2001

OBJECTIVE: In 1991, a randomized study was published and demonstrated that use of nonsurgical therapy (chemoradiation) provided similar survival to total laryngectomy (the gold standard) for patients with advanced-stage laryngeal cancer. The purpose of this study was to assess how treatment of advanced laryngeal cancer was influenced by such developments in non-surgical therapy. STUDY DESIGN: Patterns of care study using National Cancer Database (1985-2001). RESULTS: The percentage of advanced-stage patients treated with chemoradiation increased from 8.3% to 20.8% while the proportion treated with radiation alone decreased from 38.9% to 23.0%. Use of chemoradiation increased at a significantly faster rate after the 1991 publication at both community cancer centers and teaching research facilities. The use of total laryngectomy decreased slightly during this period. CONCLUSIONS: The use of chemoradiation increased after the 1991 publication. It was impossible to determine from the NCDB whether additional patients who could benefit from chemo-RT were not offered or did not complete this treatment option. We recommend that treatment recommendations discussed at tumor boards be recorded in cancer registries.     

CO2-laser treatment of recurrent glottic carcinoma.

BACKGROUND: Evaluation of the results of CO2 laser treatment of recurrent glottic carcinoma after radiotherapy. METHODS: Records of all patients treated in the University Hospital Rotterdam and the Dr. Daniel den Hoed Cancer Center between 1980 and 1996 by CO2 laser for recurrent glottic carcinoma were studied. RESULTS: Forty patients were treated by laser surgery. Average follow-up was 77 months. Twenty-three patients (58%) had another recurrence develop after laser surgery. Three were cured by a second laser procedure. Therefore, 20 patients (50%) were successfully treated with laser surgery. In 23 patients the recurrence did not extend into the anterior commissure; in 57% a total laryngectomy could be avoided. In 17 patients the recurrence did extend into the anterior commissure; in 41% a total laryngectomy was avoided. CONCLUSION: Most patients with recurrent carcinoma of the larynx after radiotherapy can be cured by laser surgery if the tumor does not extend into the anterior commissure.     

Is Intensive Follow-Up Really Able to Improve Prognosis of Patients With Local Recurrence After Curative Surgery for Rectal Cancer?

Background: Because more than 90% of local recurrences after curative surgery for rectal cancer appear within the first 36 months after surgery, an intensive and strict follow-up program during this period could improve early diagnosis and, thus, prognosis of patients.Methods: Of the 216 patients who underwent surgery for rectal cancer, 127 entered an intensive follow-up program (median follow-up: 42 months); the clinical outcome of the remaining 89 patients was reconstructed with the help of their general practitioners.Results: Fifty eight (26.8%) of the 216 patients who were treated with curative surgery alone developed a local recurrence; pelvic recurrences were prevalent. Eleven (30.5%) of the 36 patients who had recurrence during follow-up, and 6 of the 22 who had not undergone follow-up, had a reoperation with curative intent; the median survival was 19 months vs. 8 months, respectively (P 5 ns). Four (44.4%) curative reoperations were performed on the 9 asymptomatic patients and in 13 (26.5%) of the 49 cases with symptomatic local recurrences. Median survival was 15 months vs. 14 months, respectively (P 5 n.s). All patients except one (living after 42 months from reoperation) died within 48 months.Conclusions: In our study, adherence to a strict follow-up program unfortunately proved to be ineffective for improving long-term survival for patients who underwent reoperation with curative intent.     

Thyroid dysfunction in laryngectomees-10 years after treatment

BACKGROUND: Hypothyroidism is 1 of the complications that follow treatment of various head and neck cancers. In the literature, reviews using different primary sites and differences in treatment modalities make comparison of post-treatment hypothyroidism not possible. The objective of this study was to evaluate the incidence of hypothyroidism in a homogenous group of patients who were treated with total laryngectomy and irradiation for laryngeal carcinoma and to assess the importance of different variables in the occurrence of hypothyroidism. METHODS: A retrospective review of 147 total laryngectomy patients between 1993 and 2003 was carried out. Serum thyroxine level and free T4 levels were assessed in all patients. Hypothyroidism was classified as subclinical (increased thyroid-stimulating hormone and normal free T4 levels) and clinical (increased thyroid-stimulating hormone and decreased free T4 levels). RESULTS: The results showed that the overall incidence of hypothyroidism was 49% (44% subclinical and 5% clinical). Hemithyroidectomy and advanced tumor staging were risk factors for the development of hypothyroidism in these patients (p < .05) with a relative risk of 2.1 (CI 95%, 1.4-3.1) and 1.3 (CI 95%, 1.1-1.6), respectively. During follow-up, 19.9% of patients developed hypothyroidism at 3 years, 38.6% at 6 years; at 10 year follow-up, 93.3% of them had hypothyroidism. CONCLUSIONS: In conclusion, hypothyroidism is a frequent complication in patients treated with radiotherapy and total laryngectomy for laryngeal cancer, especially when treatment includes hemithyroidectomy. These patients should have their thyroid function evaluated periodically even 10 years after treatment.     

Second Biopsy of Axillary Sentinel Lymph Node for Reappearing Breast Cancer After Previous Sentinel Lymph Node Biopsy

Background Sentinel lymph node biopsy (SLNB) is a safe and accurate axillary staging procedure for patients with primary operable breast cancer. An increasing proportion of these patients undergo breast-conserving surgery, and 5% to 15% will develop local relapses that necessitate reoperation. Although a previous SLNB is often considered a contraindication for a subsequent SLNB, few data support this concern. Methods Between January 2000 and June 2004, 79 patients who were previously treated at our institution with breast-conserving surgery and who had a negative SLNB for early breast cancer developed, during follow-up, local recurrence that was amenable to reoperation. Eighteen of these patients were offered a second SLNB because of a clinically negative axillary status an average of 26.1 months after the primary event. Results In all 18 patients (7 with ductal carcinoma-in-situ and 11 with invasive recurrences), preoperative lymphoscintigraphy showed an axillary sentinel lymph node, with a preoperative identification rate of 100%, and 1 or more SLNs (an average of 1.3 per patient) were surgically removed. Sentinel lymph node metastases were detected in two patients with invasive recurrence, and a complete axillary dissection followed. At a median follow up of 12.7 months, no axillary recurrences have occurred in patients who did not undergo axillary dissection. Conclusions Second SLNB after previous SLNB is technically feasible and likely effective in selected breast cancer patients. A larger population and longer follow-up are necessary to confirm these preliminary data.     

Prognostic value of histologic tumor regression, thymidylate synthase, thymidine phosphorylase, and dihydropyrimidine dehydrogenase in rectal cancer UICC Stage II/III after neoadjuvant chemoradiotherapy

Histologic tumor regression (TR) in rectal cancer after preoperative chemoradiotherapy (CT/RT) may be useful as a surrogate end point for early treatment efficacy, but little is known about its prognostic value. The aim of this follow-up study was to evaluate whether TR is able to predict prognosis in rectal cancer patients. Furthermore, the prognostic value of thymidylate synthase (TS)-gene, thymidine phosphorylase (TP)-gene, and dihydropyrimidine dehydrogenase (DPD)-gene expression after neoadjuvant CT/RT was determined. Forty patients with rectal cancer cUICC stage II/III, receiving preoperative 5-fluorouracil (5-FU) based CT/RT were studied for therapy-induced TR and categorized as "responders" or "nonresponders" according to their TR-grade. Posttherapeutical TS-gene, TP-gene, and DPD-gene expression on surgical resection specimens was quantified by TaqMan real-time PCR after microdissection. During a median follow-up of 58 months, cancer recurrence occurred in 28%. A significant correlation was seen between disease-free survival and lymph node status (P<0.001). All patients, who developed cancer recurrence had a posttherapeutical positive lymph node status. The majority of patients with cancer recurrence were "responders" (91%) after CT/RT. There was a significant correlation between posttherapeutical TS-gene expression and cancer recurrence within the subgroup of "responders." TS-gene expression was significantly higher in patients with cancer recurrence than in those, who are disease-free up to date (P=0.028). In conclusion, lymph node status remains the most important prognostic marker in rectal cancer patients, whereas posttreatment TR by itself has no prognostic significance. Furthermore, measurement of posttherapeutical TS-gene expression may help to identify patients at higher risk for cancer recurrence.     

Postlaryngectomy pharyngocutaneous fistula: incidence, predisposing factors, and therapy.

OBJECTIVE: The pharyngocutaneous fistula (PCF) is a serious complication after total laryngectomy, and its etiology is not well understood yet. The aim of our study was to evaluate predisposing factors, incidence, and management of this complication. STUDY DESIGN AND SETTING: This was a retrospective study of 268 patients who underwent total laryngectomy in our clinic (January 1990-December 2001). A number of factors potentially predisposing to PCF formation were evaluated. RESULTS: A PCF was observed in 16% of patients. Systemic diseases, previous radiotherapy, supraglottic origin of tumor, and concurrent radical neck dissection were significantly associated with PCF. Spontaneous closure was noted in 28 patients, whereas a surgical closure was necessary in 15 patients. CONCLUSIONS: In presence of a specific risk factor, PCF can be expected; nevertheless, its prevention remains very difficult. Moreover, given the high percentage of spontaneous closure, we suggest the "wait and see" approach for 28 days before proceeding with a surgical approach. EBM RATING: C.     

Effect of obesity on the prognosis and recurrence of prostate cancer after radical prostatectomy: a meta-analysis

BackgroundObesity has been found to be closely related to the increased risk of fatal prostate cancer (PCa), however there remains no evidence that further clarifies the relationship between obesity and the postoperative recurrence and poor prognosis of PCa. In this study, a systematic review and meta-analysis were performed to systematically evaluate the effect of obesity on the prognosis and recurrence of PCa after radical prostatectomy (RP).MethodsA literature search of the PubMed, Web of Science, and Embase databases was performed covering articles published between January 2013 and January 2020. Articles regarding the correlation between body mass index (BMI) and the prognosis and recurrence of PCa following RP were included in the meta-analysis. Two investigators independently screened the literature and extracted relevant data including publication information, key results, number of cancer cases, and multivariable-adjusted odds ratios (ORs) with 95% confidence intervals (CIs). Meta-analysis was performed using RevMan 5.3 and Stata 16.0 software, and forest plots, funnel plots, and sensitivity analysis were also conducted.ResultsA total of 14 articles were included, all of which were analyzed for clinicopathological characteristics. Eight articles reported the biochemical recurrence (BCR) with prostate-specific antigen (PSA) as the predictor, and six articles reported the positive surgical margins (PSM). The meta-analysis showed that obese PCa patients had more postoperative recurrence and poor prognosis compared with the normal weight PCa patients, and the difference was statistically significant (OR =1.25, 95% CI: 1.10, 1.43). BCR exhibited no significant difference between obese and non-obese PCa patients after surgery (OR =1.2, 95% CI: 0.96, 1.46), and there were also no notable differences in PSM between the groups (OR =1.16, 95% CI: 0.99, 1.36). Subgroup analysis showed that obese PCa patients in the Americas (95% CI: 1.11, 1.37) and Europe (95% CI: 1.11, 1.78) were more likely to have surgical recurrence and poor prognosis (OR =1.40). Obese patients in the Americas were also more likely to have BCR after surgery (95% CI: 1.07, 1.36).ConclusionsObesity easily leads to poor prognosis and recurrence of PCa after RP.     

Long-term prognosis of gallbladder cancer diagnosed after laparoscopic cholecystectomy

BACKGROUND: Several clinical and laboratory studies concerning port-site recurrence have raised the concern that laparoscopic procedures might worsen the prognosis of malignant disease. However, the long-term prognosis of patients with malignancy who undergo laparoscopic surgery is still unknown. The purpose of this study was to examine the long-term prognosis of patients with unexpected gallbladder cancer diagnosed after laparoscopic cholecystectomy (LC). METHODS: A clinicopathologic study was performed on 41 patients with postoperatively diagnosed gallbladder cancer from among 5,027 patients undergoing LC at 24 institutions. The cumulative survival rate was compared with that reported for gallbladder cancer diagnosed after open cholecystectomy (OC). RESULTS: Of 26 patients with early gallbladder cancer (pTis or pT1), 23 were simply followed up, and 9 of 15 patients with advanced cancer (pT2 or pT3) had additional resection after the diagnosis of gallbladder cancer. Port-site recurrence occurred in four patients, and two of them died of the cancer. However, at this writing, the other two are still alive after abdominal wall resection or radiation therapy, having survived for 31 and 71 months, respectively. The 5-year survival rate was 92% for early cancer and 59% for advanced cancer. These results were comparable with 5-year survival rates for gallbladder cancer diagnosed after OC. CONCLUSIONS: Although port-site recurrence occurred in four patients with advanced gallbladder cancer, the long-term prognosis of patients with undiagnosed gallbladder cancer who underwent LC was not worsened by the laparoscopic procedure. We conclude that surgeons can perform LC with reasonable confidence, even if the lesion is possibly malignant.
