Oncological Outcome After Lymph Node Dissection for Cutaneous Squamous Cell Carcinoma.

BACKGROUND: Although cutaneous squamous cell carcinoma (cSCC) is common, lymph node metastases are relatively rare and are usually treated with lymph node dissection (LND). The aim of this study was to describe the clinical course and prognosis after LND for cSCC at all anatomical locations. METHODS: A retrospective search at three centres was performed to identify patients with lymph node metastases of cSCC who were treated with LND. Prognostic factors were identified by uni- and multivariable analysis. RESULTS: A total of 268 patients were identified with a median age of 74. All lymph node metastases were treated with LND, and 65% of the patients received adjuvant radiotherapy. After LND, 35% developed recurrent disease both locoregionally and distantly. Patients with more than one positive lymph node had an increased risk for recurrent disease. 165 (62%) patients died during follow-up of whom 77 (29%) due to cSCC. The 5-year OS- and DSS rate were 36% and 52%, respectively. Disease-specific survival was significantly worse in immunosuppressed patients, patients with primary tumors >2cm and patients with more than one positive lymph node. CONCLUSIONS: This study shows that LND for patients with lymph node metastases of cSCC leads to a 5-year DSS of 52%. After LND, approximately one-third of the patients develop recurrent disease (locoregional and/or distant), which underscores the need for better systemic treatment options for locally advanced cSCC. The size of the primary tumor, more than one positive lymph node, and immunosuppression are independent predictors for risk of recurrence and disease-specific survival after LND for cSCC.

Prognosis of Patients with Cutaneous Angiosarcoma After Surgical Resection with Curative Intent: Is There a Difference Between the Subtypes?

BACKGROUND: The etiology of cutaneous angiosarcoma (cAS) may be idiopathic (I-cAS), or arise secondary to radiotherapy (RT-cAS), in chronic lymphedema (ST-cAS), or related to UV exposure (UV-cAS). The aim of this study was to evaluate oncological outcomes of different cAS subtypes. PATIENTS AND METHODS: Non-metastatic cAS patients, treated with surgery for primary disease with curative intent, were retrospectively analyzed for oncological outcome, including local recurrence (LR), distant metastases (DM), and overall survival (OS). RESULTS: A total of 234 patients were identified; 60 I-cAS, 122 RT-cAS, 9 ST-cAS, and 43 UV-cAS. The majority was female (78%), the median age was 66 years (IQR 57-76 years), the median tumor size was 4.4 cm (IQR 2.5-7.0 cm), and most common site of disease was the breast (59%). Recurrence was identified in 66% (44% LR and/or 41% DM), with a median follow up of 26.5 months (IQR 12-60 months). The 5-year OS was estimated at 50%, LRFS at 47%, and DMFS at 50%. There was no significant difference in LR, DM, or OS between the subtypes. Age < 65 years and administration of radiotherapy (RT) were significantly associated with lower LR rates (HR 0.560, 95% CI 0.3373-0.840, p = 0.005 and HR 0.421, 95% CI 0.225-0.790, p = 0.007, respectively), however no prognostic factors were identified for development of DM. Development of DM, but not LR (p = 0.052), was significantly associated with decreased OS (HR 6.486, 95% CI 2.939-14.318 p < 0.001). CONCLUSION: We found no significant difference in oncological outcome between the different cAS subtypes. OS remains relatively poor, and RT is associated with lower LR rates.

Oncological Outcome After Diagnostic Biopsies in Gastrointestinal Stromal Tumors: A Retrospective Cohort Study.

OBJECTIVE: To analyze whether the route of preoperative biopsy influences oncological outcome in GIST patients. SUMMARY OF BACKGROUND DATA: Preoperative biopsies are widely used for diagnosing GIST. Little is known about the risk of tumor seeding after different routes of biopsy. METHODS: Patients who underwent resection of a primary GIST between 1996 and 2014 were identified from 2 databases from 2 tertiary referral centers. Survival data were obtained using the Kaplan-Meier method. Possible confounders were identified using Cox regression analysis. The primary endpoint was local recurrence free survival (RFS) and the secondary endpoint was DSS. RESULTS: A total of 228 patients were included, with a median age of 62 years (range 17-86) and a median follow-up time of 53 months (range 1-204). From these patients, 42 patients did not have a biopsy (18%), 70 underwent a transcutaneous biopsy (31%), and 116 a transluminal biopsy (51%). A total of 42 patients (19.0%) had a local and/or distant recurrence. From the 70 patients with a transcutaneous biopsy, only 1 patient developed a needle tract recurrence (1.4%). Local RFS and DSS were both significantly shorter in the transcutaneous biopsy group on univariate analysis compared to the other groups; however, in multivariate analysis the route of biopsy did not influence local RFS (P = 0.128) or DSS (P = 0.096). CONCLUSIONS: Transluminal or transcutaneous biopsies for diagnosing GIST do not significantly alter the risk of local recurrent disease or DSS in multivariate Cox regressions. The risk of needle tract seeding after transcutaneous biopsy was low.

[A woman with a skin lesion suspected for melanoma]. / Een vrouw met een voor melanoom verdachte plek.

We saw a 59-year-old patient who was treated with dabrafenib and trametinib because of metastatic melanoma. She had an asymptomatic, black-blue macula in the excision scar. Histopathology showed tumoral melanosis. This is an histological term for dermal aggregates of melanophages, associated with regression of melanoma.

Outcome after surgical treatment of dermatofibrosarcoma protuberans: Is clinical follow-up always indicated?

BACKGROUND: Dermatofibrosarcoma protuberans (DFSP) is a rare soft tissue sarcoma for which clinical examination up to 10 years is recommended. The objective of this study was to identify prognostic factors for recurrences and metastases that can be used to evaluate the validity of follow-up schedules after treatment for DFSP. METHODS: Patients with DFSP who received treatment between 1991 and 2016 at 3 tertiary centers were included. Cox regression analyses were conducted to identify variables associated with the primary endpoints. RESULTS: In total 357 patients were included, with a median age of 38 years (age range, 2-87 years) and a median follow-up of 60 months (interquartile range, 24-115 months). Eighty-one patients developed recurrent disease (22.7%), and the median time to recurrence was 55.5 months (interquartile range, 20-90 months). Of these, 50 tumors (61.7%) were identified by patient self-examination, whereas 3 recurrences (3.7%) were identified at clinical surveillance. For the remaining 28 tumors, no information was available on how the recurrences were identified (34.6%). Fibrosarcomatous change (hazard ratio, 21.865; P < .001), and positive resection margins (hazard ratio, 14.645; P < .001), were independent prognostic factors for recurrence. Metastases occurred in 4 patients (1.1%). All tumors were identified by imaging after patients presented with symptomatic metastases. Fibrosarcomatous change (P < .001) and tumor size >5 cm (P = .014) were associated with the development of metastases. CONCLUSIONS: Disease recurrence after resection of DFSP remains a significant issue, whereas metastases are uncommon. The majority of recurrences are identified by patient self-examination. Consideration should be given to individualized follow-up schedules based on risk factors for recurrences and metastases.

Isolated limb perfusion for unresectable extremity cutaneous squamous cell carcinoma; an effective limb saving strategy.

BACKGROUND: A small minority of patients present with locally advanced cutaneous Squamous Cell Carcinoma (cSCC). The aim of this study was to evaluate the effectiveness of Tumour necrosis factor α (TNF) and melphalan based isolated limb perfusion (TM-ILP) as a limb saving strategy for locally advanced extremity cSCC. METHODS: A retrospective search from prospectively maintained databases, at two tertiary referral centers, was performed to identify patients treated with TM-ILP for locally advanced cSSC of an extremity between 2000 and 2015. RESULTS: A total of 30 patients treated with TM-ILP for cSCC were identified, with a median age of 71 years (36-92) and 50% female. Response could not be evaluated in 3 patients. After a median follow up of 25 months, the overall response rate was 81% (n = 22), with 16 patients having a complete response (CR, 59%). A total of 7 patients developed local recurrence, with a median time to recurrence of 9 months (Interquartile Range 7-10). Progressive disease was observed in 5 patients (19%). Limb salvage rate was 80%. The overall 2-year survival was 67%. CONCLUSIONS: TM-ILP should be considered as an option in patients with locally advanced cSCC in specialised centers, resulting in a high limb salvage rate.

Practical Applications of Delayed-Immediate Autologous Breast Reconstruction: A Flexible and Safe Operative Strategy.

BACKGROUND: Timing is an important consideration in patients undergoing mastectomy for breast cancer. While immediate reconstruction results in superior aesthetic outcomes, the need for postmastectomy radiation can often only be ascertained after review of surgical pathology. Delayed-immediate autologous reconstruction (DIAR) is a reconstructive approach that consists of mastectomy with tissue expander placement in the first stage and flap-based breast reconstruction in the second stage. We describe our institution's experience with DIAR to characterize the reasons in which patients opt for this reconstructive approach and analyze its ultimate outcomes. METHODS: We conducted an institutional review board-approved retrospective chart review of all consecutive patients undergoing DIAR performed by the senior author from 2007 to 2016. Data gathered included demographics, operative techniques, and postoperative outcomes. RESULTS: In our study, 17 patients and 26 breasts underwent DIAR. Seven patients initially planned for and eventually underwent DIAR. Ten patients initially planned for implant-based reconstructions but ultimately underwent DIAR instead. Flap types included deep inferior epigastric perforator (n = 6), superficial inferior epigastric artery (n = 2), and muscle-sparing free transverse rectus abdominis myocutaneous (n = 18). The mean time between mastectomy and reconstruction was 208 days. Complications included tissue expander infection, vascular compromise, abscess formation, hematoma, and skin necrosis. CONCLUSIONS: The delayed-immediate approach allows for breast reconstruction with aesthetic and psychosocial benefits, while enabling postmastectomy radiation in patients with advanced disease. We describe modifications to DIAR, including use of a flap skin paddle and prolonged time between stages, which allow for broader applicability. We show that DIAR accommodates a range of patient preferences with few complications.

Analysis of Aesthetic Outcomes and Patient Satisfaction After Delayed-Immediate Autologous Breast Reconstruction.

BACKGROUND: Patients with breast cancer frequently opt to undergo breast reconstruction after mastectomy. The timing and aesthetic outcome of the breast reconstruction may be affected by the need for radiation therapy (RT). Delayed-immediate autologous reconstruction (DIAR) is a novel surgical approach for patients in whom the need for adjuvant RT after mastectomy is preoperatively unknown. AIM: We sought to evaluate the difference in clinical outcomes, patient satisfaction, and cosmetic results between DIAR and patients who underwent delayed autologous reconstruction. MATERIALS AND METHODS: A total of 19 DIAR and 19 delayed patients were retrospectively included.Patient demographics, surgical characteristics, and complications were obtained from patient files. Patients scored their satisfaction using the breast-Q questionnaire, and independent reviewers scored cosmetic outcomes, including skin quality/color, scar formation, symmetry, breast contour/size/position, and overall aesthetic outcome. The DIAR patients were matched to delayed patients based on age, body mass index, and unilateral or bilateral reconstruction. RESULTS: The median age in the delayed group was 48 years (range, 31-61 years) and 46 years (range, 29-64 years) in the DIAR group, with a median body mass index of 28.8 (range, 21.4-40.5) and 28.6 (range, 24-1.9), respectively.There were no significant differences in demographics between the two groups. In total, 16 patients underwent unilateral reconstruction and 22 patients bilateral reconstruction. Delayed-immediate autologous reconstruction was associated with a higher infection rate compared with delayed reconstruction, 8 and 1, respectively (P = 0.026). All infections in the DIAR group were tissue expander-related. The DIAR patients had significantly better breast contour/size/position and overall aesthetics compared with the delayed reconstruction group (P = 0.001). In addition, patients who did not receive RT had significant better cosmetic outcome (P < 0.001). There were no significant differences in patient satisfaction between the DIAR and delayed group. CONCLUSION: Delayed-immediate autologous reconstruction should be considered as an option for patients wanting autologous reconstruction when the need for RT remains unknown. Delayed-immediate autologous reconstruction demonstrates better breast contour/size/position and overall aesthetic outcome.

Critical Evaluation of Risk Factors of Infection Following 2-Stage Implant-Based Breast Reconstruction.

Infection is a dreaded complication following 2-stage implant-based breast reconstruction that can prolong the reconstructive process and lead to loss of implant. This study aimed to characterize outcomes of reconstructions complicated by infection, identify patient and surgical factors associated with infection, and use these to develop an infection management algorithm. METHODS: We performed a retrospective review of all consecutive implant-based breast reconstructions performed by the senior author (2006-2015) and collected data regarding patient demographics, medical history, operative variables, presence of other complications (necrosis, seroma, hematoma), and infection characteristics. Univariate and multivariate binomial logistic regression analyses were performed to identify independent predictors of infection. RESULTS: We captured 292 patients who underwent 469 breast reconstructions. In total, 14.1% (n = 66) of breasts were complicated by infection, 87.9% (n = 58) of those were admitted and given intravenous antibiotics, 80.3% (n = 53) of all infections were cleared after the first attempt, whereas the remaining recurred at least once. The most common outcome was explantation (40.9%; n = 27), followed by secondary implant insertion (21.2%; n = 14) and operative salvage (18.2%; n = 12). Logistic regression analysis demonstrated that body mass index (P = 0.01), preoperative radiation (P = 0.02), necrosis (P < 0.001), seroma (P < 0.001), and hematoma (P = 0.03) were independent predictors of infection. CONCLUSIONS: We observed an overall infectious complication rate of 14.1%. Heavier patients and patients who received preoperative radiation were more likely to develop infectious complications, suggesting that closer monitoring of high risk patients can potentially minimize infectious complications. Further, more aggressive management may be warranted for patients whose operations are complicated by necrosis, seroma, or hematoma.

The Impact of a Plastic Surgeon's Gender on Patient Choice.

Background: In the patient-driven market of aesthetic surgery, an understanding of the factors that patients consider in their choice of surgeon can inform the individual plastic surgeon's marketing strategy. Previous studies have investigated patient gender preferences for physicians in other specialties, but none has investigated whether patients consider gender when choosing a plastic surgeon. Objectives: The purpose of this study is to determine the impact of a plastic surgeon's gender on patient choice. Methods: A prospective study was conducted in a single private practice of two plastic surgeons, one male and one female, both closely matched in training, experience, and reputation. Two hundred consecutive patients calling for a consultation were asked if they preferred a male or female doctor; their preference, age, and area(s) of interest were recorded. Results: All patients were women. Nearly half (46%) had no gender preference, 26% requested a female surgeon, and 1% requested a male. Preference for a female surgeon was significant (Binomial-test: P < 0.001). The remaining 27% requested a specific doctor, with slightly more requesting (53.7%) the male surgeon by name, than requested the female surgeon by name (46.3%), a difference that was not statistically significant (P = 0.683). Conclusions: Most female patients interested in aesthetic surgery have no gender preference. Of those who do, nearly all requested a female plastic surgeon. More important than a plastic surgeon's gender, however, is a plastic surgeon's reputation.
