RESUMO

Financial stress and lack of financial well-being are significant contributors to physician burnout. Many trainees believe little can contribute to developing financial freedom during their training years. However, residency is a pivotal moment in a young attending's life; strategic financial steps taken during this time can lead to a path of financial freedom and well-being for years to come. Methods: We introduce 12 effective financial steps physicians can take at the start of their careers. These essential steps were compiled both anecdotally and from published financial resources such as White Coat Investigator and the Millionaire Next Door. Steps include building your "why," becoming financially educated, eliminating debt, attaining insurance, optimizing contracts, awareness of self-net worth, budgeting, maximizing investment strategies, smart investing, wise spending, K.I.S.S, and creating a personal financial plan. Results: As an example, an IRA is a retirement account set up by you, and to take advantage of the tax benefits, you must have a modified adjusted gross income of less than $124,000 as a single tax filer for 2022. Most physicians are compensated at a rate higher than this; however, there is a legal loophole to take advantage of to allow earners to still contribute to a Roth IRA that is discussed. Conclusions: Financial education is the first step toward a path to financial success in a young physician's life. Implementation of these 12 financial steps early in a physician's career will enrich one's financial freedom and well-being.

RESUMO

To detail the early experience with and results of a transfeminine (TF) genital reconstruction at an established plastic surgery practice in Western New York. METHODS: Between June 2016 and June 2019, 30 patients underwent penile inversion vaginoplasty for TF gender reassignment. All patients fulfilled World Professional Association for Transgender Health and NY State criteria for reassignment surgery. All surgeries were carried out at a large, government-owned tertiary care center. RESULTS: There were 30 patients in this retrospective study, with a mean age of 37 years (SD 5.4) and a mean body mass index of 27.3 kg/m2 (SD 3.2 kg/m2). Nineteen patients never smoked, 4 were former smokers, and 7 were current smokers. Primary surgery was an orchiectomy and modified single-stage penile inversion vaginoplasty. Mean operative time was 6.0 hours. Mean initial hospital stay was 8.2 days. Three of the 30 (10%) patients required transfusion. There were 6 (20%) complications. Three complications (10%) required reoperation: 1 patient for wound dehiscence on postoperative day 7, 1 for rectal perforation identified on postoperative day 10, and 1 for urethrovaginal fistula. All complications were addressed without sequalae. Twenty of the 30 (66%) patients have undergone revision surgery. Indications for revision were prolapse correction/deepening, labiaplasty, clitoral hood construction/revision, meatal asymmetry, urinary fistula repair, and posterior vaginal flap revision. Twenty-one of 28 (75%) revisions were outpatient surgeries. There were no complications from these procedures. Overall satisfaction via survey was 92% (24 respondents). CONCLUSIONS: TF gender reassignment is a novel, challenging set of procedures for the specialty of plastic surgery. With appropriate consideration and technique, penile inversion vaginoplasty is a safe, effective means of achieving this goal.

RESUMO

OBJECTIVES/HYPOTHESIS: The indications for and efficacy of induction chemotherapy in the management of squamous cell carcinoma of the head and neck is controversial. With the advent of human papillomavirus (HPV)-related cancers, survival has improved significantly. Here we present a group of patients with tonsil cancer treated with induction chemotherapy followed by surgery. STUDY DESIGN: Retrospective cohort study. METHODS: Thirty-eight patients with tonsil cancer were treated with induction chemotherapy, consisting of cisplatin and docetaxel, followed by neck dissection and radical tonsillectomy. Twenty-six patients were HPV+, 28 were nonsmokers or long-term former smokers, and 28 were T1/T2. Fourteen patients required postoperative chemoradiotherapy (CRT). Median follow-up time was 4.1 years. RESULTS: A complete response to induction chemotherapy was achieved in 45% (17) of patients. In total, 76% (29/38) of patients were successfully treated: 53% (20/38) with chemotherapy and surgery alone, and 24% (9/38) required postoperative CRT. Almost 90% (23/26) of HPV+ and half (6/12) of HPV- patients are no evidence of disease (NED). HPV status is a significant prognostic factor (P = .02). Only 38% (5/13) of current smokers were NED compared to 96% (24/25) of nonsmokers (P = .0002). All HPV+ nonsmokers (20/20) were NED at last follow-up. CONCLUSIONS: In this study, the primary driver of prognosis was smoking status. HPV status and T stage were also important. The prognosis for HPV+ nonsmokers is extremely good; most likely regardless of treatment. Treatment failures have a poor chance of salvage, irrespective of treatment type. With the major exception of HPV- smokers, induction chemotherapy followed by surgery with selective CRT is a viable treatment option for tonsil cancer.

RESUMO

BACKGROUND AND OBJECTIVES: The management of the clinically N0 (cN0) neck is controversial for early stage squamous cell carcinoma of the oral cavity (OSCC). This paper represents a single institution series analyzing the efficacy of sentinel lymph node biopsy (SNB) for early stage oral cavity cancers. METHODS: From 2005 to 2017, 108 patients with cN0 OSCC were treated with primary resection and SNB. Patients with positive biopsy results proceeded to neck dissection with or without adjuvant chemoradiotherapy. Mean follow-up for the entire cohort was 50.8 months (range: 8-147 months). Clinically, 56 patients were T1N0, 49 patients were T2N0, and three patients were T3N0 or greater. RESULTS: Disease-specific survival was 93% within the entire cohort. Sentinel lymph nodes were identified in 95.4% of patients. Twenty one patients had a positive biopsy. There were seven false-negative biopsies. The overall rate of nodal disease was 26%. Accuracy of node biopsy was 93%, with sensitivity of 75%, and negative predictive value of 91%. Recurrence rate was 19% (20/108), with an overall survival of 60% in this subgroup. CONCLUSION: SNB is a safe, effective, and well tolerated method for staging cN0 OSCC.

RESUMO

Human papillomavirus 16 (HPV-16) infection and tobacco use are associated with human oropharyngeal cancers. We conducted a study of the role of HPV and tobacco use in base of the tongue (BOT) cancers. DNA from 34 such cancers was subjected to HPV-16 and HPV-18-specific polymerase chain reaction analysis. Demographic and clinicopathologic data were obtained from each patient's medical record. HPV-16 was detected in 68% of tumors. Tobacco use was the only factor found to be significantly associated with HPV status. Tumors from 100% of patients who had never used tobacco tested positive for HPV, compared with only 56% of those who had ever used tobacco (Fisher exact test, p = 0.024). All tumors were associated with either tobacco use or HPV infection. These findings are consistent with the hypothesis that either tobacco use or HPV infection is necessary to the etiology of BOT tumors, and they suggest that tongue base carcinoma may be prevented by combining HPV vaccination with tobacco avoidance.

RESUMO

IMPORTANCE: Neck dissection is the standard staging procedure to ascertain the pathologic status of cervical lymph nodes in patients with oral cavity squamous cell carcinoma (OSCC), but it results in multiple morbidities. OBJECTIVE: To examine outcomes of patients with OSCC who underwent sentinel node biopsy (SNB) as the sole neck staging procedure. DESIGN: Retrospective review of patients who underwent SNB during the period 2005 through 2011. SETTING: National Cancer Institute­designated comprehensive cancer center. PARTICIPANTS: Thirty-eight patients with clinically T1 or T2N0 OSCC. INTERVENTIONS: Preoperative lymphoscintigraphy with intraoperative gamma probe localization was used. Sentinel lymph nodes were serially sectioned, formalin fixed, and examined at 3 levels. All patients with positive SNB results underwent neck dissection, and the patients with negative SNB results were observed clinically. MAIN OUTCOMES AND MEASURES: Sensitivity and predictive value of SNB, recurrence rates, and disease-specific survival rates. RESULTS: There were 18 T1 and 20 T2 tumors. Five patients had positive SNB results, of whom 3 had additional positive nodes on subsequent neck dissection. Two of 33 patients with negative SNB results developed a regional recurrence. The sensitivity and negative predictive value for staging the neck with SNB alone were 71% (5 of 7) and 94% (31 of 33), respectively. Mean follow-up was 31 months. The mean disease-free survival duration for patients with positive and negative SNB results was 30 and 65 months, respectively (P = .08). The disease-specific survival rate for patients with positive and negative SNB results was 80% and 91%, respectively. There was no significant difference in disease-specific survival between patients with true-negative and false-negative SNB results (34 vs 44 months; P = .38). CONCLUSIONS AND RELEVANCE: The majority of patients with positive results on SNB had additional positive nodes on neck dissection. A low rate of isolated neck recurrence was found in patients with negative results on SNB. Individuals with negative results on SNB exhibited better overall and disease-specific survival than those with positive results.

RESUMO

BACKGROUND: A 270-degree partially tubed pectoralis major myocutaneous flap (PMMF) is an excellent option for total circumferential pharyngoesophageal defects in patients who are not candidates for more complex reconstructions. METHODS: Patients undergoing circumferential pharyngoesophageal reconstruction with partially tubed PMMF were reviewed. End points were stricture, fistula, resumption of oral intake, perioperative death, and recurrence. RESULTS: Eleven patients underwent 270-degree PMMF for reconstruction: 6 (55%) were men and 5 (45%) were women (mean, 62 years; range, 42-78 years). Three patients (27%) developed fistulas and 2 (18%) developed stenosis. Ten patients (91%) were able to resume adequate nutrition via oral intake. There were no perioperative deaths. CONCLUSIONS: Patients with severe comorbidities, metastatic disease, a lack of donor vessels, or a potentially hostile abdomen may not be ideal candidates for free tissue transfer. For these patients, partially tubed PMMF using the prevertebral fascia provides a reliable alternative for reconstruction with excellent functional results.

RESUMO

BACKGROUND: The purpose of this study was to quantify the effect of treatment duration on locoregional progression after definitive concurrent chemoradiation (CCRT) for squamous cell carcinoma of the head and neck (SCCHN). METHODS: We conducted a retrospective chart review of patients treated between 2004 and 2010. After a prior analysis, measures were taken to limit therapy beyond 7 weeks. Comparison of outcomes were made between cohorts 1 (2004-2007, n = 78) and 2 (2007-2010, n = 62). RESULTS: Median therapy duration was statistically significantly different between cohorts as follows: 51 days, cohort 1 and 46 days, cohort 2 (p < .01). Locoregional progression in cohorts 1 and 2 was 19% and 5% (p = .01), respectively. On multivariate analysis, patients with prolonged treatment (≥57 days) had an 8-fold increase in risk of locoregional progression compared to patients who completed on time (p < .01). CONCLUSION: Treatment duration was a significant predictor of locoregional progression in patients with SCCHN who received definitive CCRT.

RESUMO

BACKGROUND: This study was carried out to determine if markers of nutritional status predict for locoregional failure following intensity-modulated radiation therapy (IMRT) with concurrent chemoradiotherapy (CCRT) for squamous cell carcinoma of the head and neck (SCCHN). METHODS: We performed a retrospective chart review of 78 patients with SCCHN who received definitive CCRT. We compared patient factors, tumor characteristics, and nutritional status indicators between patients with and without locoregional failure. RESULTS: Fifteen of 78 patients (19%) experienced locoregional failure. Median follow-up for live patients was 38 months. On univariate analysis, pretreatment percentage of ideal body weight (%IBW) (p < .01), pretreatment hemoglobin (p = .04), and treatment duration (p < .01) were significant predictors of failure. On multivariate analysis, pretreatment %IBW (p = .04) and treatment time (p < .01) remained statistically significant. CONCLUSIONS: Although treatment time is an accepted risk factor for failure, differences in outcome for patients with head and neck cancer undergoing definitive CCRT based on pretreatment %IBW should be examined further.

RESUMO

Human papillomavirus (HPV) types 16 and 18 are causally related to a sub-set of oral cavity and oropharyngeal squamous cell cancers. However, a clear estimate of the prevalence of HPV-16/18 in oral cavity and oropharyngeal dysplasia (OOPD) is not available. This literature review and meta-analysis was conducted to provide a prevalence estimate for HPV-16/18 in OOPD. Twenty-two studies that reported prevalence of HPV-16 and/or 18 in 458 OOPD lesions were analyzed. Meta-analysis was used to evaluate the prevalence of HPV-16/18 and logistic regression was used for stratified analysis by age, gender, and histological grade. The overall prevalence of HPV-16/18 in OOPD lesions was 24.5% [95% confidence interval (CI), 16.4-36.7%)]. The individual prevalence for HPV-16 alone was 24.4%. The prevalence of HPV-16/18 in oral cavity lesions alone was 25.3% (95% CI, 14.2-45.2%). The odds of detection of HPV-16/18 in dysplastic lesions in males were twice that of females [odds ratio (OR), 2.44]. HPV-16/18 were 3 times more common in dysplastic lesions (OR, 3.29; 95% CI, 1.95-5.53%) and invasive cancers (OR, 3.43; 95% CI, 2.07-5.69%), when compared to normal biopsies. There was no significant difference in HPV-16/18 rates between dysplastic lesions and cancers or between mild, moderate or severe dysplastic lesions. This meta-analysis provides a quantification of the prevalence of HPV types 16/18 in OOPD lesions. These results also support the assumption that HPV-16/18 infection occurs during the early phase of the oral cavity and oropharyngeal carcinogenesis.

RESUMO

We describe a brief staff training program to improve the delivery of tobacco cessation services to patients with head and neck cancers. This study utilized a quasi-experimental design to compare the delivery of smoking cessation components and outcomes among patients exposed to either usual care (UC) or an enhanced cessation (EC) program implemented following a 1-h staff education program. Of the 179 subjects enrolled, 112 were recontacted by phone 1 month after their clinic visit. More patients in EC compared to UC reported that they were asked about their smoking status (94.2% vs. 76.6%, p = 0.01), advised to quit (92.3% vs. 72.3%, p = 0.01), prescribed cessation medications (30.8% vs. 3.3%, p < 0.001), and received a support call (53.8% vs. 11.7%, p < 0.001) at the 1-month follow-up. Quit attempts and quit rates between groups were similar. The EC intervention improved the delivery of cessation services in a busy clinical setting, but this failed to increase cessation rates after 1 month.

RESUMO

Early detection of oral premalignant lesions (OPL) and oral cancers (OC) is critical for improved survival. We evaluated if the addition of autofluorescence visualization (AFV) to conventional white-light examination (WLE) improved the ability to detect OPLs/OCs. Sixty high-risk patients, with suspicious oral lesions or recently diagnosed untreated OPLs/OCs, underwent sequential surveillance with WLE and AFV. Biopsies were obtained from all suspicious areas identified on both examinations (n = 189) and one normal-looking control area per person (n = 60). Sensitivity, specificity, and predictive values were calculated for WLE, AFV, and WLE + AFV. Estimates were calculated separately for lesions classified by histopathologic grades as low-grade lesions, high-grade lesions (HGL), and OCs. Sequential surveillance with WLE + AFV provided a greater sensitivity than WLE in detecting low-grade lesions (75% versus 44%), HGLs (100% versus 71%), and OCs (100% versus 80%). The specificity in detecting OPLs/OCs decreased from 70% with WLE to 38% with WLE + AFV. Thirteen of the 76 additional biopsies (17%) obtained based on AFV findings were HGLs/OCs. Five patients (8%) were diagnosed with a HGL/OC only because of the addition of AFV to WLE. In seven patients, additional HGL/OC foci or wider OC margins were detected on AFV. Additionally, AFV aided in the detection of metachronous HGL/OC in 6 of 26 patients (23%) with a history of previously treated head and neck cancer. Overall, the addition of AFV to WLE improved the ability to detect HGLs/OCs. In spite of the lower specificity, AFV + WLE can be a highly sensitive first-line surveillance tool for detecting OPLs/OCs in high-risk patients.

RESUMO

The overall purpose of this study was to establish human head and neck squamous cell carcinoma (HNSCC) xenografts in mice by transplantation of surgical tumor tissue and to characterize the growth, histologic and vascular properties of these xenografts. Primary surgical specimens of HNSCC were xenografted into eight-to-twelve week old severe combined immunodeficiency (SCID) mice. Histologic features of primary HNSCC specimens, initial and established xenografts were compared for tumors established from three different head and neck subsites, namely, oral cavity, larynx and base of tongue (one tumor per site). Growth rates of xenografts were compared along with magnetic resonance imaging (MRI) measures of tumor vascularity and correlative CD31-immunostaining. Initial and established xenografts from all three sites demonstrated a squamous phenotype similar to the original patient tumor histology. Established xenografts of oral cavity and larynx exhibited increased keratinization (H&E) compared to initial xenografts and the primary tumor. No differences in tumor growth rates were observed between established xenografts from the different subsites. Xenografts established from SCC of the larynx exhibited increased microvessel density and lumen area (CD31 staining) along with enhanced permeability to the MR contrast agent compared to oral cavity and base of tongue tumors. Our results show that the combination of non-invasive imaging along with histologic evaluation of patient tumor xenografts offers a valuable platform for preclinical investigations in head and neck cancer. However, it is important to recognize the influence of tumor-host interactions on the histologic phenotype of transplanted tumors.

RESUMO

Substantial evidence supports an association between chronic infections/inflammation, and cancer. The aim of this study was to assess the effect of chronic periodontitis on head and neck squamous cell carcinoma (HNSCC). The study population consisted of new patients at the Department of Dentistry and Maxillofacial Prosthetics, Roswell Park Cancer Institute between 1999 and 2005. Cases were patients diagnosed with primary HNSCC. Controls were all patients seen during the same time period but negative for malignancy. Patients age <21 years, edentulous, immunocompromised, and those with history of cancer were excluded. Periodontitis was measured by alveolar bone loss (ABL) from panoramic radiographs by one examiner blind to cancer status. A total of 473 patients (266 cases and 207 controls) were included in the study. Each millimeter of ABL was associated with >4-fold increased risk of HNSCC (odds ratio, 4.36; 95% confidence interval, 3.16-6.01) after adjustment for age, gender, race/ethnicity, marital status, smoking status, alcohol use, and missing teeth. The strength of the association was greatest in the oral cavity, followed by oropharynx and larynx. The association persisted in subjects who never used tobacco and alcohol. There was a significant interaction between smoking and ABL (P = 0.03). Patients with periodontitis were more likely to have poorly differentiated oral cavity SCC than those without periodontitis (32.8% versus 11.5%; P = 0.038). This study suggests that chronic periodontitis is an independent risk factor for HNSCC and smoking modifies this association. These results have implications for practical and safe strategies for prevention, diagnosis, and treatment of HNSCC.

RESUMO

OBJECTIVE: To determine the response of dysplasia, carcinoma in situ (CIS), and T1 carcinoma of the oral cavity and larynx to photodynamic therapy with porfimer sodium. DESIGN: Prospective trial. SETTING: A National Cancer Institute-designated cancer institute. PATIENTS: Patients with primary or recurrent moderate to severe oral or laryngeal dysplasia, CIS, or T1N0 carcinoma. INTERVENTION: Porfimer sodium, 2 mg/kg of body weight, was injected intravenously 48 hours before treatment. Light at 630 nm for photosensitizer activation was delivered from an argon laser or diode laser using lens or cylindrical diffuser fibers. The light dose was 50 J/cm(2) for dysplasia and CIS and 75 J/cm(2) for carcinoma. MAIN OUTCOME MEASURES: Response was evaluated at 1 week and at 1 month and then at 3-month intervals thereafter. Response options were complete (CR), partial (PR), and no (NR) response. Posttreatment biopsies were performed in all patients with persistent and recurrent visible lesions. RESULTS: Thirty patients were enrolled, and 26 were evaluable. Mean follow-up was 15 months (range, 7-52 months). Twenty-four patients had a CR, 1 had a PR, and 1 had NR. Three patients with oral dysplasia with an initial CR experienced recurrence in the treatment field. All the patients with NR, a PR, or recurrence after an initial CR underwent salvage treatment. Temporary morbidities included edema, pain, hoarseness, and skin phototoxicity. CONCLUSION: Photodynamic therapy with porfimer sodium is an effective treatment alternative, with no permanent sequelae, for oral and laryngeal dysplasia and early carcinoma. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT00530088.
