ABSTRACT

Introducción: La herida es una pérdida de continuidad de la piel o mucosa producida por algún agente físico o químico. Una herida es "compleja" cuando por su extensión, localización, profundidad o exposición de elementos nobles, necesita para su curación una terapéutica especial. Este es el caso de heridas con compromiso tisular que afecta a estructuras como músculos, fascias, tendones, huesos, vasos sanguíneos, nervios o las lesiones de lenta evolución como úlceras o escaras. Objetivos: Determinar el método de reconstrucción más utilizado en el manejo terapéutico de las heridas complejas del tercio distal de la pierna en los pacientes atendidos en el Hospital de Trauma y en la Unidad de Cirugía Plástica de la FCM - UNA. Materiales y métodos: Estudio de diseño observacional, tipo de estudio descriptivo y retrospectivo. Fueron incluidos pacientes de ambos sexos, mayores de edad, con heridas complejas en el tercio distal de la pierna, atendidos en el Hospital de Trauma y en la Unidad de Cirugía Plástica de la FCM - UNA, durante el periodo 2010 al 2019. Resultados: Se incluyó a 112 pacientes de los cuales el 80,36 % fue hombres y el 19,64 % mujeres. Las edades estaban comprendidas entre los 18 y los 73 años y una media de 33,8 ± 14 años. La edad más frecuente fue 18 años. La mediana de edad es de 30 años, lo que implica que la mitad de la muestra tuvo por lo menos dicha edad. En cuanto a la procedencia, el 41,07 % era del interior, el 30,36 % del departamento Central y el 28,57 % restante de Asunción. En cuanto al mecanismo de la lesión, se puede observar que el mecanismo más frecuente fue el accidente de tráfico, seguido por caída de altura, en un gran porcentaje. En cuanto a la evolución y complicaciones se puede ver que 92 individuos, o sea 82 % de los pacientes no tuvo ninguna evolución negativa o complicaciones. Lo más común fue la infección con 1,9% de prevalencia, la pérdida parcial del colgajo o piel representan el 2,4%, dehiscencia de la sutura el 0,9 %, hematoma 0,6 % y pérdida total del colgajo 0,54 %. En cuanto al tratamiento aplicado, se debe tener en cuenta que los pacientes pudieron haber recibido más de un tratamiento por lo que el tamaño de la muestra se refiere a las visitas. El tratamiento más frecuente fue el colgajo sural con 28,57%, tutor externo con el 20,19%, injerto de piel 16,46%, toillete 12,73% y colgajo fascio - cutáneo en 6,21%. Conclusión: La gran mayoría de los casos tratados corresponde a algún tipo de accidente de tránsito. Se necesita de un equipo multidisciplinario: ortopedistas, cirujanos plásticos, cirujanos vasculares, fisioterapeutas, etc. en trabajo coordinado para tratar estas graves lesiones de forma a obtener resultados favorables. Para la cobertura de la pierna traumatizada, con exposición ósea, recurrimos a los colgajos musculares, en el 1/3 proximal el gemelo, en el 1/3 medio el sóleo. Para la cobertura del 1/3 distal de la pierna utilizamos el colgajo neuro-veno-fascio-cutáneo (sural) a pedículo distal.


Introduction: The wound is a loss of continuity of the skin or mucosa produced by some physical or chemical agent. A wound is "complex" when due to its extension, location, depth, exposure of noble elements, it requires special therapy to heal. This is the case of wounds with tissue involvement that affects structures such as muscles, fascia, tendons, bones, blood vessels, nerves, or slowly evolving lesions such as ulcers or bedsores. Objectives: Determine the reconstruction method most used in the therapeutic management of complex wounds of the distal third of the leg in patients treated at the Trauma Hospital and the Plastic Surgery Unit of the FCM - UNA. Materials and methods: Observational, descriptive, and temporally retrospective study. Patients of both sexes, of legal age, with complex wounds in the distal third of the leg, treated at the Trauma Hospital and in the Plastic Surgery Unit of the FCM - UNA, during the period 2010 to 2019, were included. Results: 112 patients were included, of which 80.36% are men and 19.64% are women. The ages range from 18 to 73 years and an average of 33.8 ± 14 years. The most common age was 18 years. The median age is 30 years, which implies that half of the sample is at least that age. Regarding origin, 41.07% are from the interior, 30.36% from the Central department and the remaining 28.57% from Asunción. Regarding the mechanism of injury, the most frequent mechanism was a traffic accident, followed by a fall from a height, in a large percentage. Regarding the evolution and complications, 92, that is, 82% of the patients do not have any negative evolution or complications. The most common was infection with 1.9%, partial loss of the flap or skin represented 2.4%, suture dehiscence with 0.9%, hematoma 0.6%, and total loss of the flap 0.54. %. Regarding the treatment applied, it must be considered that patients may have received more than one treatment, so the sample size refers to visits. The most frequent treatment was the sural flap with 28.57%, external tutor with 20.19%, skin graft 16.46%, toilette 12.73% and fasciocutaneous flap in 6.21%. Conclusion: Most cases treated correspond to some type of traffic accident. A multidisciplinary team is needed: orthopedists, plastic surgeons, vascular surgeons, physiotherapists, etc. in coordinated work to treat these serious injuries to obtain favorable results. To cover the traumatized leg, with bone exposure, we resort to muscle flaps. In the proximal 1/3, the gastrocnemius. In the middle 1/3, the soleus. To cover the distal 1/3 of the leg we used the neuro-veno-fascio-cutaneous (sural) flap to the distal pedicle.

ABSTRACT

Objective: To investigate the efficacy of humanized anti-CD25 monoclonal antibody for steroid-refractory acute graft-versus-host disease (SR-aGVHD) in allogeneic hematopoietic stem cell transplantation (allo-HSCT) recipients. Methods: A total of 64 patients with SR-aGVHD between June 2019 and October 2020 in Suchow Hopes Hematology Hospital were enrolled in this study. Humanized anti-CD25 monoclonal antibodies 1 mg·kg(-1)·d(-1) were administered on days 1, 3, and 8, and then once per week according to the disease progression. Efficacy was assessed at days 7, 14, and 28 after humanized anti-CD 25 treatment. Results: Of the 64 patients with a median age of 31 (15-63) years, 38 (59.4%) were male and 26 (40.6%) were female. The overall response (OR) rate of the humanized CD25 monoclonal antibody in 64 patients with SR-aGVHD on days 7, 14, and 28 were 48.4% (31/64), 53.1% (34/64), and 79.7% (51/64), respectively. Liver involvement is an independent risk factor for poor efficacy of humanized CD25 monoclonal antibody for SR-aGVHD at day 28 (OR=9.588, 95% CI 0.004-0.291, P=0.002). The median follow-up time for all patients was 17.1 (0.2-50.8) months from the start of humanized CD25 monoclonal antibody therapy. The 1- and 2-year OS rates were 63.2% (95% CI 57.1% -69.3%) and 52.6% (95% CI 46.1% -59.1%), respectively. The 1- and 2-year DFS rates were 58.4% (95% CI 52.1% -64.7%) and 49.8% (95% CI 43.4% -56.2%), respectively. The 1- and 2-year NRM rates were 28.8% (95% CI 23.1% -34.5%) and 32.9% (95% CI 26.8% -39.0%), respectively. The results of the multifactorial analysis showed that liver involvement (OR=0.308, 95% CI 0.108-0.876, P=0.027) and GVHD grade Ⅲ/Ⅳ (OR=9.438, 95% CI 1.211-73.577, P=0.032) were independent risk factors for OS. Conclusion: Humanized CD25 monoclonal antibody has good efficacy and safety for SR-aGVHD. This study shows that SR-aGVHD with pretreatment grade Ⅲ/Ⅳ GVHD and GVHD involving the liver has poor efficacy and prognosis and requires early intervention.

ABSTRACT

ABSTRACT Purpose: Prostate cancer (PCa) is the second most common oncologic disease among men. Radical treatment with curative intent provides good oncological results for PCa survivors, although definitive therapy is associated with significant number of serious side-effects. In modern-era of medicine tissue-sparing techniques, such as focal HIFU, have been proposed for PCa patients in order to provide cancer control equivalent to the standard-of-care procedures while reducing morbidities and complications. The aim of this systematic review was to summarise the available evidence about focal HIFU therapy as a primary treatment for localized PCa. Material and methods: We conducted a comprehensive literature review of focal HIFU therapy in the MEDLINE database (PROSPERO: CRD42021235581). Articles published in the English language between 2010 and 2020 with more than 50 patients were included. Results: Clinically significant in-field recurrence and out-of-field progression were detected to 22% and 29% PCa patients, respectively. Higher ISUP grade group, more positive cores at biopsy and bilateral disease were identified as the main risk factors for disease recurrence. The most common strategy for recurrence management was definitive therapy. Six months after focal HIFU therapy 98% of patients were totally continent and 80% of patients retained sufficient erections for sexual intercourse. The majority of complications presented in the early postoperative period and were classified as low-grade. Conclusions: This review highlights that focal HIFU therapy appears to be a safe procedure, while short-term cancer control rate is encouraging. Though, second-line treatment or active surveillance seems to be necessary in a significant number of patients.

ABSTRACT

Objective: To investigate the survival outcomes and prognostic factors of patients with salvage surgery for hypopharyngeal carcinoma after radiotherapy. Methods: A retrospective analysis was performed, including 26 patients treated in Ningbo Medical Center Lihuili Hospital between January 2010 and December 2015. All patients were males, aged 48-83 years, of whom 8 cases were local residual after radiotherapy alone, 8 cases were local recurrence after postoperative radiotherapy, 2 cases were residual of cervical lymph nodes after radiotherapy alone, 2 cases were recurrence of cervical lymph nodes after radiotherapy alone, 2 cases were recurrence of cervical lymph nodes after postoperative radiotherapy and 4 cases were recurrence of tracheal stoma. The salvage operations included: local resection, local resection with neck dissection, simple neck dissection, tumor resection of tracheostomy, and additional repair according to the defect. Chi square test was used for recurrence and metastasis analysis, Kaplan-Meier method for survival analysis, Log-rank test for univariate analysis, and Cox regression model for multivariate analysis. Results: The complication rate of salvage surgery was 23.1% (6/26). The recurrence rate was 65.4% (17/26) and the distant metastasis rate was 42.3% (11/26) in the 5-year follow-up after salvage surgery. Patient's age and tumor invasion extent were correlated with recurrence. Initial treatment, tumor persistence or recurrence after radiotherapy, recurrence location and tumor invasion extent were correlated with distant metastasis (all P<0.05). Overall, 3 year and 5 year survival rates were 42.3% and 23.1% respectively. Age, recurrence location, surgical margin and tumor invasion extent were related to prognosis (χ²=6.56, 10.68, 9.32, and 7.90 respectively, all P<0.05). Multivariate analysis showed that surgical margin and tumor invasion extent were independent risk factors for prognosis (OR (95%CI) = 3.19 (1.03-9.84), 14.37 (2.46-84.08), both P<0.05). Conclusion: Salvage surgery is the first choice for patients with recurrence after radiotherapy for hypopharyngeal carcinoma. Safe surgical margin should be ensured, especially in tumors invading muscle, bone tissue or lymph node capsule.

ABSTRACT

To efficiently remove all recurrent lymph nodes (rLNs) and minimize complications, we developed a combination approach that consisted of 68Gallium prostate-specific membrane antigen (PSMA) ligand positron emission tomography (PET)/computed tomography (CT) and integrated indocyanine green (ICG)-guided salvage lymph node dissection (sLND) for rLNs after radical prostatectomy (RP). Nineteen patients were enrolled to receive such treatment. 68Ga-PSMA ligand PET/CT was used to identify rLNs, and 5 mg of ICG was injected into the space between the rectum and bladder before surgery. Fluorescent laparoscopy was used to perform sLND. While extensive LN dissection was performed at level I, another 5 mg of ICG was injected via the intravenous route to intensify the fluorescent signal, and laparoscopy was introduced to intensively target stained LNs along levels I and II, specifically around suspicious LNs, with 68Ga-PSMA ligand PET/CT. Next, both lateral peritonea were exposed longitudinally to facilitate the removal of fluorescently stained LNs at levels III and IV. In total, pathological analysis confirmed that 42 nodes were rLNs. Among 145 positive LNs stained with ICG, 24 suspicious LNs identified with 68Ga-PSMA ligand PET/CT were included. The sensitivity and specificity of 68Ga-PSMA ligand PET/CT for detecting rLNs were 42.9% and 96.6%, respectively. For ICG, the sensitivity was 92.8% and the specificity was 39.1%. At a median follow-up of 15 (interquartile range [IQR]: 6-31) months, 15 patients experienced complete biochemical remission (BR, prostate-specific antigen [PSA] <0.2 ng ml-1), and 4 patients had a decline in the PSA level, but it remained >0.2 ng ml-1. Therefore, 68Ga-PSMA ligand PET/CT integrating ICG-guided sLND provides efficient sLND with few complications for patients with rLNs after RP.

ABSTRACT

ABSTRACT Prostate cancer is the most common invasive cancer in men. Radical prostatectomy (RP) is a definitive treatment option, but biochemical recurrence can reach 40%. Salvage lymphadenectomy is a relatively recent approach to oligometasis and has been rapidly diffused primarily due to improvement in imaging diagnosis and results showing possibly promising therapy. A systematic literature review was performed in March 2020, according to the PRISMA statement. We excluded studies with patients with suspicion or confirmation of visceral and / or bone metastases. A total of 27 articles were included in the study. All studies evaluated were single arm, and there were no randomized studies in the literature. A total of 1,714 patients received salvage lymphadenectomy after previous treatment for localized prostate cancer. RP was the most used initial therapeutic approach, and relapses were based on PET / CT diagnosis, with Coline-11C being the most widely used radiopharmaceutical. Biochemical response rates ranged from 0% to 80%. The 5 years - Free Survival Biochemical recurrence was analyzed in 16 studies with rates of 0% up to 56.1%. The articles do not present high levels of evidence to draw strong conclusions. However, even if significant rates of biochemical recurrence are not evident in all studies, therapy directed to lymph node metastases may present good oncological results and postpone the onset of systemic therapy. The long-term impact in overall survival and quality of life, as well as the best strategies for case selection remains to be determined.

ABSTRACT

La recurrencia de carcinoma de células escamosas orofaríngeo (CCEOF) se asocia a mal pronóstico, particularmente en recurrencias en etapa avanzada. La cirugía en el contexto de rescate es más complicada por el tratamiento oncológico del tumor primario, por lo tanto, tiene un mayor riesgo de complicaciones y estadía hospitalaria. Sin embargo, la cirugía de rescate es la mejor oportunidad del paciente como tratamiento curativo y para supervivencia a largo plazo. La población de pacientes que reciben tratamiento para CCEOF ha cambiado en la última década, se ha reconocido que la incidencia de virus papiloma humano (VPH) asociado a CCEOF ha generado el gran aumento de CCEOF y el cambio asociado en las características de la población de pacientes, ahora los pacientes son más jóvenes y tienen menos comorbilidades. Con el aumento exponencial en la incidencia de CCEOF, la necesidad de cirugía de rescate en CCEOF podría verse en aumento. En vista del aumento de la incidencia de casos con carcinoma escamoso de orofaringe y su importante relación con el VPH, esta revisión se enfoca en la supervivencia tras cirugía de rescate con intención curativa y evaluar si con los avances en su tratamiento ha mejorado su pronóstico.


Recurrence of oropharyngeal squamous cell carcinoma (OPSCC) is associated with poor prognosis, particularly in advanced stage recurrences. Salvage surgery is complicated by previous oncological treatment of the primary tumor, therefore, it has a higher risk of complications and hospital stay. However, salvage surgery is the patient's best opportunity as a curative treatment and for long-term survival. The population of patients receiving treatment for OPSCC has changed in the last decade, it has been recognized that the incidence of human papilloma virus (HPV) associated OPSCC has generated an increase of OPSCC and changes in the epidemiology of the patient population, with younger patients and with less comorbidities. With the exponential increase in the incidence of OPSCC, the need for salvage surgery in OPSCC could increase in the future. In view of the increase in the incidence of cases with squamous oropharyngeal carcinoma and its relationship with HPV, this review focuses on survival after salvage surgery with curative intent and assessing whether the progress in its treatment has improved its prognosis.

ABSTRACT

INTRODUCCIÓN Y OBJETIVOS La artroplastia de resección de hombro (ARH) se presenta como una técnica obsoleta y una opción no válida en la actualidad, debido a la evolución de las técnicas quirúrgicas y de los implantes. Pero, como consecuencia del aumento exponencial del uso de artroplastias de hombro, están aumentando en paralelo el número de fracasos e infecciones, con necesidad de revisión y rescate. Es por ello que, en determinadas situaciones y pacientes, esa técnica vuelve a ser una opción necesaria como salvataje, aunque tiene un alto coste funcional. El objetivo de nuestro trabajo, es presentar dos casos de artroplastia de resección de hombro como una opción válida de tratamiento en la actualidad y la revisión de la literatura. CASOS Se presentan dos casos de ARH como tratamiento de rescate, en un caso de osteomielitis crónica de cabeza humeral y un caso de infección de hemiartroplastia de hombro. Ambos pacientes se encontraban sin dolor y libres de infección con un seguimiento de más de 30 meses. En un caso la funcionalidad fue limitada con un Constant de 45 pero el otro caso la funcionalidad fue aceptable con un Constant de 67. CONCLUSIONES La ARH sigue siendo una técnica útil tras el fracaso de procedimientos de revisión, para resolver infecciones protésicas recalcitrantes u osteomielitis. Los resultados funcionales son pobres, por lo que debe reservarse para pacientes con baja demanda funcional y como salvataje, tras agotar otras opciones.


INTRODUCTION AND OBJECTIVES shoulder resection arthroplasty (SRA) is currently considered as an outdated technique, due to the advances in surgical techniques and new prosthesis designs. However, with the exponential increase in the use of shoulder arthroplasties, the number of failures and infections is equally increasing, as well as the revisions and salvage procedures. In certain situations, SRA is therefore a necessary solution, although it grossly compromise shoulder function. The aim of our study is to present two cases who underwent SRA as a valid treatment option nowadays and a literature review. CASES We present two cases of SRA as salvatage treatment. First case in a chronic humeral head osteomyelitis and second in a partial shoulder prosthesis recalcitrant infection. Both patients had complete pain relief and infection was solved with a follow-up over 30 months. In the first case, postoperative shoulder function was limited with a Constant­Murley score of 45. In the second case, function was fairly good with a Constant of 67. CONCLUSIONS SRA remains a valuable technique after the failure of revision procedures, as a salvage for recalcitrant prosthetic infections or osteomyelitis. The functional results are poor, so it should be reserved for patients with low functional demand and as salvatage procedure, after assess other options.

ABSTRACT

Diabetic foot ulcers (DFUs) is a severe complication of the diabetes mellitus, which is the first leading cause of non-traumatic lower limbs amputations. The pathogenesis of diabetic foot involves a variety of mechanisms, treatment involves the department of foot and ankle surgery, department of vascular surgery, endocrinology, and infection control. Treatment need multidisciplinary diagnosis and treatment. Debridement is the basis of treating diabetic foot ulcers, and the normal anatomical structure should be maintained during the process. Vacuum sealing drainage (VSD) and antibiotic-laden bone cement (ALBC) have more advantages of controlling infection and ulceration wound healing, which could receive good clinical effect. Tendon lengthening could alleviate the problem of ulcer occurrence and progression caused by stress concentration on the bottom of foot, which has widely application and has advantages of preventing formation of foot ulcers. Flap transplantation could solve the problem of wound healing, but it is necessary to consider whether the transplanted flap could bear the same function as plantar tissue. Tibial bone transverse distraction is a relatively new technique, and the mechanism is not clear, but it has certain application prospects from the perspective of clinical efficacy.

ABSTRACT

Penile prosthesis implant (PPI) remains an effective and safe treatment option for men with erectile dysfunction (ED). However, PPI surgery can be associated with a higher risk of complications in certain populations. This article provides a critical review of relevant publications pertaining to PPI in men with diabetes, significant corporal fibrosis, spinal cord injury, concurrent continence surgery, and complex salvage cases. The discussion of each category of special populations includes a brief review of the surgical challenges and a practical action-based set of recommendations. While specific patient populations posed considerable challenges in PPI surgery, strict pre- and postoperative management coupled with safe surgical practice is a prerequisite to achieving excellent clinical outcomes and high patient satisfaction rate.

ABSTRACT

OBJECTIVES: The outcomes of refractory and relapsed acute myeloid leukemia (AML) patients in developing countries are underreported, even though the similar classic regimens are widely used. METHODS: We conducted a retrospective comparison of "MEC" (mitoxantrone, etoposide, and cytarabine) and "FLAG-IDA" (fludarabine, cytarabine, idarubicin, and filgrastim) in adults with first relapse or refractory AML. RESULTS: In total, 60 patients were included, of which 28 patients received MEC and 32 received FLAG-IDA. A complete response (CR) rate of 48.3% was observed. Of the included patients, 16 (27%) died before undergoing bone marrow assessment. No statiscally significant difference in CR rate was found between the two protocols (p=0.447). The median survival in the total cohort was 4 months, with a 3-year overall survival (OS) rate of 9.7%. In a multivariable model including age, fms-like tyrosine kinase 3 (FLT3) status, and stem-cell transplantation (SCT), only the last two indicators remained significant: FLT3-ITD mutation (hazard ratio [HR]=4.6, p<0.001) and SCT (HR=0.43, p=0.01). CONCLUSION: In our analysis, there were no significant differences between the chosen regimens. High rates of early toxicity were found, emphasizing the role of supportive care and judicious selection of patients who are eligible for intensive salvage therapy in this setting. The FLT3-ITD mutation and SCT remained significant factors for survival in our study, in line with the results of previous studies.

ABSTRACT

ABSTRACT Objective: To build a model to evaluate the impact of salvage radiotherapy (SRT) in men with PSA rise or persistent PSA after undergoing radical prostatectomy (RP). Materials and Methods: The study included 107 node-negative patients treated with SRT after RP at a single institution. Patients received SRT for either prostate-specific antigen (PSA) rising, or PSA persistence after RP. All patients received local radiation to the prostate / seminal vesicle bed. The primary measured outcome was the biochemical recurrence (BCR) free survival. Multivariable Cox regression analysis was used to develop a risk-stratification group to identify predictive factors associated with the probability of BCR at 5yr. Results: At a median follow-up of 52 months, the BCR free survival rate and overall survival in 5 years was 73% and 94%, respectively. At multivariable analysis, pre-SRT PSA level > 0.35ng / mL (p = 0.023), negative margins (p = 0.038), and seminal vesicles invasion (p = 0.001) were significantly associated with BCR free survival. Three risk groups using regression analysis for SRT administration was built. Low-, intermediate- and the high-risk groups had a BCR free survival in 5-years of 96%, 84%, and 44% (p = 0.0001), respectively. Conclusions: We developed a risk group stratification to show the impact of SRT based on prostate cancer characteristics. SRT showed to be extremely beneficial for patients with low- and intermediate-risk tumors. Moreover, the risk-group built could identify patients classified as high-risk who might benefit from more aggressive treatment for SRT.

ABSTRACT

RESUMEN El cáncer de laringe avanzado y el cáncer de hipofaringe pueden ser tratados con terapia de conservación de órganos con radioquimioterapia, sin embargo, cuando esta última fracasa, la cirugía es la última opción para esta patología. El cáncer de hipofaringe posee una pobre sobrevida en estados avanzados, y su tratamiento quirúrgico después de radioterapia siempre se transforma en un desafío quirúrgico por las condiciones del tejido irradiado. Este artículo realiza una revisión general de las opciones de reconstrucción para defectos faringolaríngeos tanto parciales como circunferenciales, ante el caso eventual de que por la extensión tumoral y su tratamiento ablativo no sea posible un cierre primario. Se revisan distintos resultados de los principales colgajos utilizados en reconstrucción en cabeza y cuello, como son los colgajos libres fasciocutáneos, colgajo pectoral mayor y colgajos viscerales como el yeyuno, comparando tasas de fistulas faringocutáneas, resultados en deglución y rehabilitación fonatoria posterior, intentando realizar una aproximación a una recomendación terapéutica. Por último cabe mencionar que todo servicio de cabeza y cuello debe conocer las opciones existentes para cada paciente en particular, ya que además de buscar resultados oncológicos, se debe intentar lograr buenos resultados funcionales que no empobrezcan la calidad de vida de nuestros pacientes.


ABSTRACT Advanced laryngeal cancer and hypopharyngeal cancer can be treated with organ preservation therapy with radiochemotherapy. However, when the latter fails, surgery is the last option for this pathology. Hypopharyngeal cancer has a poor survival in advanced stages, and its surgical treatment after radiotherapy always becomes a surgical challenge due to the conditions of the irradiated tissue. This article makes a general review of the reconstruction options for both partial and circumferential pharyngolaryngeal defects, in the case where tumor extensions and ablative treatments do not permit a primary closure. Different results of the main flaps used in head and neck reconstruction are reviewed, such as the fasciocutaneous free flaps, pectoralis major flap and visceral flaps such as the jejunum. We then compare the rates of pharyngocutaneous fistulas, swallowing results and posterior phonation rehabilitation, while trying to perform an approach to a therapeutic recommendation. Finally, it should be mentioned that all head and neck services must know the existing options for each patient in particular, since in addition to looking for oncological results, one should try to achieve good functional results that do not impoverish the quality of life of our patients.

ABSTRACT

PURPOSE: We evaluated the oncologic outcomes of organ-preserving strategies in patients with rectal cancer treated with preoperative chemoradiotherapy (PCRT). METHODS: Between January 2008 and January 2013, 74 patients who underwent wait-and-watch (WW) (n = 42) and local excision (LE) (n = 32) were enrolled. Organ-preserving strategies were determined based on a combination of magnetic resonance imaging, sigmoidoscopy, and physical examination 4–6 weeks after completion of PCRT. The rectum sparing rate, 5-year recurrence-free survival (RFS), and overall survival (OS) were evaluated. RESULTS: The rectum was more frequently spared in the LE (100% vs. 87.5%, P = 0.018) at last follow-up. Recurrence occurred in 9 (28.1%) WW and 7 (16.7%) LE (P = 0.169). In the WW, 7 patients had only luminal regrowth and 2 had combined lung metastasis. In the LE, 2 (4.8%) had local recurrence only, 4 patients had distant metastasis, and 1 patient had local and distant metastasis. Among 13 patients who indicated salvage surgery (WW, n = 7; LE, n = 11), all in the WW received but all of LE refused salvage surgery (P = 0.048). The 5-year OS and 5-year RFS in overall patients was 92.7% and 76.9%, respectively, and were not different between WW and LE (P = 0.725, P = 0.129). CONCLUSION: WW and LE were comparable in terms of 5-year OS and RFS. In the LE group, salvage treatment was performed much less among indicated patients. Therefore, methods to improve the oncologic outcomes of patients indicated for salvage treatment should be considered before local excision.

ABSTRACT

To explore the clinical efficacy and toxicity of the NAPD regimen(vinorelbine, cytarabine, cisplatin, and dexamethasone) in the treatment of recurrent refractory non-Hodgkin' s lymphoma.
 Methods: A total of 67 patients identified with recurrent refractory non-Hodgkin's lymphoma were enrolled for this retrospective study. The curative efficacy of NAPD regimen was evaluated after 2 consecutive cycles. The toxicities and side effects were evaluated after 1 cycle. The objective response rate (ORR), overall survival (OS), progress free survival (PFS), 1, 2 or 4 years of OS and PFS rates were analyzed. The prognosis was evaluated with univariate and multivariate analysis.
 Results: The ORR was 53.8% after two cycles, including 5(7.5%) complete responses and 31(46.3%) partial responses. The clinical benefit rate (CBR) was 88.7% (59/67). The median OS was 22 (1.5-140.0) months. 1, 2 or 4 years of OS rates were 70.9%, 49.0%, and 35.0%, respectively. The median PFS was 14 (1.5-140.0) months; and 1, 2 or 4 years of PFS rates were 57.5%, 38.3%, and 29.8%, respectively. The main side effect was myelosuppression. The rates of Grade III/IV leukopenia and thrombocytopenia were 13.4% (9 cases) and 3.0% (2 cases), respectively. Gastrointestinal toxicity was at Grade I or II and 6% patients displayed gastrointestinal toxicity at Grade III/IV. No severe cardiac and hepatorenal functional toxicity was observed.
 Conclusion: The NAPD regimen for recurrent refractory non-Hodgkin's lymphoma is effective, and its toxicity is well tolerated. It is a salvage chemotherapy regimen and be of worth to be verified.

ABSTRACT

Acute gastroesophageal variceal hemorrhage is a dreaded complication in patients with liver cirrhosis. Endoscopic therapy and radiologic intervention for gastroesophageal bleeding have rapidly developed in the recent decades. Endoscopic treatment is initially performed to stop variceal hemorrhage. For the treatment of esophageal variceal bleeding, endoscopic variceal ligation (EVL) is considered the endoscopic treatment of choice. In cases of gastric variceal hemorrhage, the type of gastric varices (GVs) is important in deciding the strategy of endoscopic treatment. Endoscopic variceal obturation (EVO) is recommended for fundal variceal bleeding. For the management of gastroesophageal varix type 1 bleeding, both EVO and EVL are available treatment options; however, EVO is preferred over EVL. If endoscopic management fails to control variceal hemorrhage, radiologic interventional modalities could be considered. Transjugular intrahepatic portosystemic shunt is a good option for rescue treatment in refractory variceal bleeding. In cases of refractory hemorrhage of GVs in patients with a gastrorenal shunt, balloon-occluded retrograde transvenous obliteration could be considered as a salvage treatment.

ABSTRACT

OBJECTIVES: Length of in-hospital stay (LOS) is often regarded as a surrogate marker of efficiency in medical care. A shorter stay can redistribute medical resources to more patients if patient outcomes would not be worsened. However, the adequate LOS remains largely understudied for a complex head and neck cancer (HNC) surgery and free flap reconstruction. METHODS: Active management of LOS (14-day LOS program) included detailed preoperative surgical planning, intensive wound care, postoperative early ambulation and positive psychological encouragement. It was applied to 43 patients undergoing HNC surgery and free flap reconstruction. Outcomes such as noninferior oncological results, rates of timely adjuvant treatments and complications were compared with those of 125 patients without active management of LOS. In addition, the medical costs of shortened LOS were compared with those of the control group. Cases undergoing HNC surgery as a salvage treatment were excluded from both groups for analyses. RESULTS: Active management of LOS resulted in less in-hospital period compared to the control group (15.0 vs. 21.0 days, P=0.001), and reduced medical costs significantly. Incidence of postoperative complications was comparable between the two groups. Oncological outcomes did not differ significantly according to LOS. In all patients in both groups, initial high T status (T3–4) and occurrence of postoperative complications were independent risk factors for long LOS (>30 days). CONCLUSION: In patients undergoing HNC surgery with free flap reconstruction as an initial treatment, a 14-day LOS could be safe in terms of comparable oncological outcomes and postoperative complications. To achieve this goal safely, careful management for T3–4 tumors and prevention of postoperative complications seem to be necessary.
