RESUMO

INTRODUCTION: Idiopathic granulomatous mastitis (IGM) often mimics breast cancer. Presentation includes pain, palpable mass, suppuration or suspicious imaging. Widely reported in Asia and the Middle East, IGM is diagnosed after excluding specific granulomatous mastitis (SGM). Aetiology remains unknown. Lactation, prolactinaemia, ethnicity, autoimmune disease and Corynebacteria are associated. Treatment is controversial and the prevalence rising. Surgery and non-operative treatments including antibiotics, non-steroidal anti-inflammatory drugs (NSAIDs), steroids, methotrexate and observation have advocates. METHODS: A retrospective chart review of 63 patients with IGM from 2008 to 2018 was undertaken focusing on birthplace, age, clinical presentation, wound cultures, imaging, treatments and outcomes. RESULTS: Sixty-one of 63 patients were Hispanic; 53 were Mexican-born women aged 23-46. Clinical presentation included pain, painful mass, painless mass, suppuration and abnormal imaging. Some 31/61 ultrasound examinations and 17/33 mammograms were deemed Breast Imaging Reporting and Data System (BI-RADS) score 4 or 5. Management included antibiotics (43), incision and drainage (24), NSAIDs (29), steroids (8), lumpectomy (18) and observation (12). Some 12/20 patients with painless masses resolved with observation, 3 received NSAIDs, 2 received steroids and 3 underwent lumpectomies. Antibiotics resolved 8/43 cases, 5 needed incision and drainage, 26 received NSAIDs, 6 received steroids and 5 underwent lumpectomies. Nineteen patients had indolent disease or recurrence. CONCLUSIONS: Excluding malignancy is critical, treatment challenging and recurrence common in IGM. A preponderance of patients were Mexican-born, similar to other reports from the USA. Over 50% of IGM cases had suspicious BI-RADS scores. Best management remains a challenge and ranges from observation to lumpectomy.

RESUMO

INTRODUCTION: The negative appendicectomy rate (NAR) is a quality metric in the management of appendicitis. While computed tomography (CT) has been associated with a low NAR, Alvarado scoring produces an acceptable NAR. The definition of negative appendicectomy may affect the NAR. This study examined the impact of CT, Alvarado score and definition on the NAR. METHODS: The charts of 1,306 emergency appendicectomy patients from 1996 to 2010 were reviewed. Three five-year cohorts were created (Cohort A: 1996-2000, Cohort B: 2001-2005, Cohort C: 2006-2010) and the NAR was calculated for each cohort using two definitions of negative appendicectomy: absence of inflammation (NAR-STD) and absence of intramural neutrophils (NAR-STR). NAR-STD was correlated to the CT rate for Cohorts B and C and also to Alvarado score for Cohort C. RESULTS: When the definition of negative appendicectomy was changed, the NAR rose from 9.2% to 15.8% (p=0.0097) for Cohort A, from 2.8% to 8.6% (p=0.0180) for Cohort B (CT rate: 80.6%) and from 3.0% to 6.7% (p=0.0255) for Cohort C (CT rate: 92.4%). The introduction of CT lowered NAR-STD from 1996-2000 (9.2%) to 2001-2010 (2.9%) but increasing the CT rate from 2001-2010 had no impact on the NAR. The positive predictive value for Alvarado score (98.60%) and CT (99.03%) were similar. CONCLUSIONS: The definition of a negative appendicectomy determines the NAR. CT reduces the NAR regardless of definition but routine CT is unnecessary for male patients with positive Alvarado scores. Early/mild appendicitis may resolve without surgery and CT may contribute to unnecessary surgery. Alvarado scoring allows selective use of CT in suspected appendicitis.

RESUMO

Metastatic melanoma continues to be one of the most devastating of all cancers. It is a heterogeneous solid tumor whose treatment is challenging and difficult. It afflicts thousands of otherwise healthy patients annually, and clinicians have yet to discover an effective treatment for locally advanced disease. Over the years, much attention has been devoted to the development of an effective adjuvant treatment for patients with resected melanoma who remain at high risk for recurrence. The new advances in the understanding of melanoma's microenvironment and the complexity of its disease process, makes it clear that the treatment approach to this disease needs to be multi-directional. Numerous studies have tested various immunotherapeutic strategies in the treatment of advanced melanoma, in particular. These strategies include melanoma vaccines, interferon-alpha, interleukin-2 (IL-2), and dendritic cell vaccines. The Dr. Wallack's Surgery Research Laboratory has been studying melanoma vaccines for the past three decades. The first generation melanoma vaccine proposed by the Laboratory showed promising results in a subset of patients. Recently, the same Laboratory has produced a second generation melanoma vaccine (DC-Melvac) that consists of five human melanoma cell lines, a recombinant vaccinia virus that encodes for IL-2, as well as dendritic cells that have been programmed to recognize certain melanoma associated antigens. DC-MelVac was recently approved by the Food and Drug Administration for its use in Phase I clinical trials. These trials are expected to be underway in the near future. The ensuing review discusses many of the immunotherapeutic strategies that have been studied in the treatment of melanoma, including DC-MelVac.

RESUMO

A phase III, randomized, double-blind, multi-institutional vaccinia melanoma oncolysate (VMO) trial was performed for patients with stage III (AJCC) melanoma. When compared with the control vaccinia virus (V) therapy, VMO therapy did not show clinical efficacy in the final analysis of data from this trial. However, the data did allude to significant therapeutic efficacy with VMO therapy if it had been compared with an observation arm. Therefore, a comparative overview statistical analysis was performed to identify the therapeutic efficacy of VMO. This review compares VMO results with data from the treatment and observation arms of other prominent randomized anti-melanoma biologic trials (i.e., ECOG EST 1684; SWOG, IFN-gamma (J. Natl. Cancer Inst. 87 (1995) 1710); WHO IFN-alfa-2a (ASCO 14 (1995) 410); Mayo IFN-alfa-2a (J. Clin. Oncol. 13 (1995) 2776); French IFN-alfa-2a (ASCO 15 (1996) 437). The analysis was carried out comparing the disease-free interval (DFI) and overall survival (OS). The analysis shows that the VMO results are fairly comparable to the results of the treatment arms from the ECOG and Mayo trials at the 5-year mark; percent DFI 0.37, 0.37, and 0.4, percent OS 0.48, 0.46, 0.47, respectively. In some cases, VMO DFI is superior to the observation arms from other studies; ECOG, Mayo, and WHO; 0.37 versus 0.26, 0.3, 0.27 (4 years), respectively. These comparative results suggest that the vaccinia arm is not a true observation arm in the VMO trial, and the VMO could have shown an enhanced efficacy had the trial included a no-treatment observation control arm.

RESUMO

Ectopic supernumerary kidney is a rare congenital urinary tract abnormality. Because of the scarcity of published cases and atypical presenting symptomatology this entity frequently causes a diagnostic as well as therapeutic dilemma. We report a case of an unusually symptomatic supernumerary kidney that presented as back pain. Noncontrast CT scan showed a suspicious left-sided para-aortic mass, which prompted a percutaneous biopsy. Intravenous contrast CT scan revealed an anatomically and functionally free supernumerary kidney. The approach to diagnosis as well as management of supernumerary kidneys is discussed herein.

RESUMO

BACKGROUND AND PURPOSE: Laparoscopic cholecystectomy (LC) is a routine procedure for most general surgeons, yet the technical aspects of gaining access to the peritoneal cavity continue to be quite diverse. We describe a prospective review of 180 LCs using three access techniques: open balloon blunt-tip trocar (BBTT), open Hasson (HA), and closed Veress needle (VN). We favor the BBTT because it is designed to avoid all sharp instrumentation and offers superior seal and mobility, as well as expeditious and easy abdominal access. PATIENTS AND METHODS: The techniques and devices were evaluated prospectively with regard to simplicity of access, leakage of carbon dioxide, access time, and complications. All patients underwent LC by one of two Board-certified surgeons. RESULTS: The mean time to insertion of the laparoscope for the BBTT (3.5 +/- 0.99 minutes) was significantly less than the insertion time for the VN technique (5.2 +/- 0.9 minutes, P < 0.05). The insertion time for the BBTT was also less than for the standard HA approach (4.25 +/- 1.0 minutes; P < 0.05). There were no visceral or vascular injuries noted, but CO2 leakage and subcutaneous insufflation of gas experienced in the standard HA and VN groups resulted in lengthened operative times. One patient in the BBTT group experienced a postoperative port-site herniation, which was repaired primarily without consequence. CONCLUSION: The BBTT is an established, safe alternative to blind access for LC. Our technique is simple and rapid and avoids most of the technical difficulties encountered by other open access devices. We believe this method provides surgeons with an option that is efficient and easier to perform than most other conventional open-access laparoscopic techniques.

RESUMO

Early dislodgment or malfunction of pacemaker leads can result in significant morbidity and therefore must be corrected promptly. We describe a method of changing pacemaker leads that is atraumatic, maintains central venous access, and eliminates the need for venipuncture. Our technique is simple, highly reproducible, and can be performed with standard operating room instruments.

RESUMO

Malignant chondroid syringoma, or mixed tumor of the skin, salivary gland type, is an uncommon neoplasm believed to originate in sweat glands. This neoplasm occurs mostly in women and is typically seen in the extremities and torso. A case of recurrent malignant chondroid syringoma of the right foot in a man aged 34 years is described with a review of pertinent literature. The surgically excised neoplasm was evaluated by routine histology, immunohistochemistry, and transmission electron microscopy. The malignant chondroid syringoma showed microscopic dermal satellite tumor nodules. Immunohistochemical staining was positive for keratin and S100 and negative for actin and p53. Ki-67 showed <10% positive staining. Ultrastructurally, the neoplasm was composed of epithelial cells with tonofilaments, cell junctions, and electron-dense amorphous keratin-like substance in the intercellular spaces. No evidence of myoepithelial differentiation was noted. Given the tumoral size, acral location, and histologic findings, the neoplasm was classified as a malignant chondroid syringoma. After reviewing the literature, it became apparent that wide surgical excision, adjuvant radiation therapy as well as patient education are critical in facilitating long-term survival.

RESUMO

Patients with advanced or recurrent gastric cancer affecting the upper and lower gastrointestinal tract usually experience obstructive symptoms, causing a severe compromise in their quality of life. Surgery may not be feasible because of the patient's precarious medical condition and multilevel tumor infiltration. When faced with these circumstances, surgeons have few options. Parenteral nutrition and comfort measures are utilized when surgical bypass is not a tenable option. We herein describe a unique case of multilevel upper and lower gastrointestinal obstruction secondary to recurrent gastric cancer. The patient was treated palliatively through a combined surgical, radiological, and endoscopic approach by implanting a series of self-expanding metallic stents. To our knowledge, there are no previous reports of successful management of simultaneous strictures of the upper and lower gastrointestinal tract using this technique.

RESUMO

A replication-deficient recombinant vaccinia virus, NYVAC, was developed by deleting 18 open reading frames in the vaccinia virus genome. Recombinant NYVAC, encoding the murine T cell co-stimulatory gene B7.1 (CD 80) (NYVAC-B7.1) and the murine interleukin-2 gene (NYVAC-IL-2), were prepared and the expression of B7.1 and the secretion of IL-2 were respectively confirmed in vitro. The use of these viruses to prepare a potent tumor cell vaccine was studied in a syngeneic murine CC-36 colon adenocarcinoma model. Mice were immunized on days 1 and 8 with 10(6) irradiated CC-36 cells that were infected with 10(7) plaque-forming units of either NYVAC-B7.1, NYVAC-IL-2 or a control virus, NYVAC-HR, which encodes a vaccinia virus host-range gene. These mice were then challenged with 10(8) viable CC-36 tumor cells on day 15. All mice (10/10) in a group that had received no vaccination and all mice (20/20) in a group that had received a control vaccine of CC-36/NYVAC-HR developed tumor 4-weeks after tumor cell challenge. Interestingly, only 16/20 mice in a group that had received CC-36/ NYVAC-B7.1 showed the development of tumor after the same interval. The protection against tumor development and the reduction in tumor burden (as mean tumor diameter, 4 weeks after tumor challenge) were significant in this group when compared to groups that were either unvaccinated or vaccinated with CC-36/NYVAC-HR (mean tumor diameter = 6.51+/-3.2 mm compared to 26.5+/-0.9 mm or 26.2+/-1.8 mm respectively) (P = < 0.05). The protection against tumor in a group of mice that received CC-36/ NYVAC-IL-2 vaccination was similar to that in the unvaccinated group or the group receiving a CC-36/NYVAC-HR control vaccination. However, in a survival experiment, mice that received either CC36/NYVAC-B7.1 or CC-36/ NYVAC-IL-2 vaccination on the day of tumor transplantation survived significantly longer than mice that had not been vaccinated (median survival 60+ days, 60+ days or 23.5 days respectively) (P = < 0.05). Interestingly, when a therapeutic tumor vaccination was performed on day 4 after tumor transplantation, mice that had been vaccinated with either CC36/NYVAC-B7.1 or CC-36/NYVAC-IL-2 did not show an improved survival when compared to mice in the control that had not been vaccinated (median survival 28 days compared to 26 days or 25 days respectively). However, mice that had received a therapeutic vaccination with CC-36 cells infected with both NYVAC-B7.1 and NYVAC-IL-2, 4 days after tumor transplantation, survived significantly longer than control mice that had not received any vaccination (median survival 29.5 days compared to 25 days respectively) (P<0.05). These results suggest that a replication-deficient recombinant NYVAC encoding the B7.1 gene and NYVAC encoding the IL-2 gene can be used to produce an effective vaccinia-virus-augmented tumor cell vaccine.

RESUMO

BACKGROUND: A phase III, randomized, double-blind, multicenter trial of active specific immunotherapy (ASI) using vaccinia melanoma oncolysate (VMO) was performed in patients with stage III (American Joint Commission on Cancer) melanoma to determine the efficacy of VMO to increase the disease-free interval (DFI) or overall survival (OS) in these patients. Two interim analyses of data from this trial were performed in May 1994 and June 1995. Although the results from these analyses showed no statistically significant improvement in DFI or OS in all patients using VMO, two subsets-men aged 44-57 years with one to five positive nodes and all patients with clinical stage I and pathologic stage II disease-showed an overall survival advantage with VMO therapy. A final analysis of data from this trial was performed in May 1996 and is reported here. The design of future melanoma vaccine trials is discussed based on information learned from this first randomized, multicenter trial of ASI therapy. STUDY DESIGN: A polyvalent VMO was prepared using melanoma cells derived from four melanoma cell lines and vaccinia vaccine virus (V). Patients were accrued from 11 United States institutions and were randomized by the Statistical Center at the University of Alabama, Birmingham. Two hundred fifty patients were randomized to treatment with either VMO (1 U containing 2 mg of total protein derived from 5 x 10(6) melanoma cells and 10(5.6) 50% tissue culture infectious dose of vaccinia virus) or control V (1 U containing 10(5.4) 50% tissue culture infectious dose of vaccinia virus) once a week for 13 weeks and then once every 2 weeks for a total of 12 months, or until recurrence. Patient data were collected by the Statistical Center and analyzed as of May 1996 for DFI and OS using Wilcoxon test and log-rank analysis. RESULTS: Two hundred seventeen patients were found to be eligible according to the inclusion criteria. Data from these patients were analyzed for DFI and OS after a median followup of 46.3 months (50.2 months for VMO and 41.3 months for V). This final analysis showed no statistically significant increase in either DFI (p = 0.61) or OS (p = 0.79) of patients treated with VMO (n = 104) compared with V (n = 113). At 2-, 3-, and 5-year intervals, 47.8%, 43.8%, and 41.7% of patients treated with VMO were disease-free, respectively, compared with 51.2%, 44.8%, and 40.4% of patients treated with V. At the same intervals, 70.0%, 60.0%, and 48.6% of patients treated with VMO survived, compared with 65.4%, 55.6%, and 48.2% of patients treated with V. In a retrospective subset analysis, male patients aged 44-57 years (n = 20) with one to five positive nodes showed 18.9%, 26.82%, and 21.3% improvement in survival at 2-, 3-, and 5-year intervals, respectively, after treatment with VMO when compared with V (n = 18) (p = 0.046). CONCLUSIONS: This study was a randomized, multicenter, placebo-controlled evaluation of an active specific immunotherapeutic agent to increase the DFI or OS of patients with stage III melanoma in a surgical adjuvant setting. In this trial, ASI with VMO when compared with V showed no difference in either DFI or OS. In a retrospective subset analysis, however, a subset of men with one to five positive nodes, between the ages of 44 and 57 years, showed a survival advantage with VMO. This result suggests that one must include a detailed subset analysis in the design of future trials of ASI for patients with American Joint Commission on Cancer stage III melanoma. An appropriate control arm also must be included in ASI trials.

RESUMO

Tracheostomy tube insertion is periodically performed when patients with acquired immunodeficiency syndrome (AIDS) require prolonged mechanical ventilation. In this population, bedside percutaneous tracheostomy may be a better technique than conventional operating room tracheostomy because it reduces procedural cost, requires no patient transport, and requires few sharp instruments, thereby potentially decreasing risk to surgical staff. A retrospective review was conducted in the Department of Medical Records at St. Vincents Hospital and Medical Center of New York City. Nine consecutive patients diagnosed with AIDS and undergoing percutaneous tracheostomy from January 1, 1992, to December 31, 1996, were identified. All patients were males (mean age 32.1 +/- 4 years, CD4 count average 145) and were ventilator-dependent for mean of 24 +/- 3 days. The procedure was successful and without complications in all patients. Follow-up was 27 months (range 1-42 months) and in-hospital mortality was 77 per cent. The average length of survival for those patients who died in the hospital was 29 days (range, 3-120). Two patients survived the hospitalization after undergoing decannulation on postoperative days 29 and 52, respectively. Despite the poor prognosis after tracheostomy in patients with AIDS this procedure allows better oral care and may improve patient comfort. Bedside percutaneous tracheostomy can be performed with less risk to surgical personnel and patient when compared to conventional surgery. This minimally invasive procedure safely and efficiently provides prolonged tracheal access in patients with AIDS.

RESUMO

Anorectal melanoma is a rare disease and, unlike cutaneous melanoma, there are few guidelines regarding optimal management. It has a reputation for having a poor prognosis, which has been attributed to a delay in diagnosis and to a lack of effective systemic therapy. It has also been suggested that the biology of this tumor may differ from that of cutaneous melanoma. An interesting case of anorectal melanoma is presented which highlights the unique considerations and challenges encountered by medical oncologists and surgeons who treat this disease.

RESUMO

A retrospective study was conducted to determine the influence of the acquired immunodeficiency syndrome (AIDS) epidemic on the incidence, clinical presentation, and outcome of primary gastrointestinal lymphoma (stages I and II) over a 20-year period at a single institution. Between 1971 and 1981, there were seven cases. Fifty-eight patients were diagnosed between 1983 and 1993, and 81 per cent were AIDS-related. The mean age overall was 50 years; 81 per cent were male, and 35 per cent presented with acute complications. All tumors were high or intermediate grade B cell lymphomas, and 48 per cent had bulky or advanced disease at presentation. The overall actuarial 5-year survival was 9 per cent. Human immunodeficiency virus status and stage were significant independent prognostic factors. The AIDS-related subgroup had a mean age of 43 years, and 91 per cent were male. Tumor resection was performed in 38 per cent, and the 5-year survival was 2 per cent. The mean age for the non-AIDS-related subgroup was 71 years, and 55 per cent were male. Resection was performed in 39 per cent, and 5-year survival was 28 per cent. AIDS-related disease accounted for the dramatic increase in incidence of primary gastrointestinal lymphoma since 1983. The prognosis for these patients is poor and is dominated by the underlying immunocompromise.

RESUMO

Gestational breast cancer is occurring with increasing incidence because more women are delaying childbirth into their thirties and forties. Although breast cancer during pregnancy or within the first year postpartum is occurring more often, there is still some confusion regarding its treatment. Although breast conservation therapy has evolved as the major treatment in breast cancer, it has been thought that pregnancy was a contraindication for this type of breast cancer therapy due to risks imposed on the fetus by chemotherapy and radiation. However, recent studies have shown that the use of chemotherapeutics during the second and third trimesters is possible. Also, if chemotherapy is initiated after a lumpectomy, radiation can be withheld until after the birth of the baby when the cancer is detected in the second or third trimester.

RESUMO

BACKGROUND: Tracheostomy tube (TT) insertion for respiratory failure in patients with acquired immunodeficiency syndrome has been associated with an early mortality rate of 100%. We have reviewed our experience with tracheostomy to determine if there is a role for this procedure among certain subgroups. METHODS: A retrospective review was conducted of 47 patients diagnosed with acquired immunodeficiency syndrome who underwent tracheostomy from 1988 to 1995. Patients were divided into three groups based on indications for tracheostomy: group 1, Pneumocystis carinii pneumonia (PCP); group 2, non-PCP pneumonia; and group 3, others (including neurosyphilis, endocarditis, and trauma). RESULTS: All groups were similar with regard to demographic details and laboratory values (mean age, 38 +/- 1.4 years; 95% male; CD4 count = 21.8 +/- 3.6 cells/microL). In the vast majority of cases the decision to place a TT was elective. Forty-three percent of all patients had signed do not resuscitate orders before endotracheal tube intubation. The mean time from endotracheal tube to TT insertion was 14.1 +/- 1.6 days. Early mortality after TT placement was dismal (91%) for group 1 patients but significantly better (47%) in group 2 patients (p = 0.04). Early mortality usually occurred within 3 weeks of TT placement (range, 1 to 54 days). The cause of pneumonia (PCP versus non-PCP) was the only statistically significant variable in predicting outcome. For those who survived to TT removal (26%), the average time to removal of TT was 67 +/- 11 days. Long-term survival was noted in 8 group 2 patients (mean, 584 days) and in 2 group 1 patients (450 days). CONCLUSIONS: Outcome after tracheostomy in patients with AIDS is generally poor. Patients with PCP should not undergo TT placement; however, patients with non-PCP pneumonia have a reasonable expected survival and should undergo the operation.
