Acr appropriateness Criteria management of vaginal cancer.

Due to its rarity, treatment guidelines for vaginal cancer are extrapolated from institutional reports and prospective studies of cervical and anal cancer. An expert panel was convened to reach consensus on the selection of imaging and therapeutic modalities. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed every 2 years by a multidisciplinary expert panel. The guideline development and review include an extensive analysis of current medical literature from peer-reviewed journals and the application of a well-established consensus methodology (modified Delphi) used by the panel to rate the appropriateness of imaging and treatment procedures. In those instances where evidence is lacking or not definitive, expert opinion may be used to recommend imaging or treatment. Four variants were developed to represent clinical scenarios in vaginal cancer management. Group members reached consensus on the appropriateness of the pretreatment evaluation and therapeutic interventions. This article represents the consensus opinion of an expert panel and may be used to inform clinical recommendations in vaginal cancer management.

ACR Appropriateness Criteria® role of adjuvant therapy in the management of early stage cervical cancer.

OBJECTIVE: The use of adjuvant treatment(s) following initial hysterectomy and retroperitoneal nodal harvesting of patients with clinical stage I and II cervical carcinoma is (are) presently based on the pathological assessment of surgical specimens. This report sought to delineate further the clinical application of potential therapeutic interventions and associated follow-up investigations of this patient cohort. METHODS: The American College of Radiology (ACR) Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed every two years by a multidisciplinary expert panel. The guideline development and review include an extensive analysis of current medical literature from peer reviewed journal and the application of a well-established consensus methodology (modified Delphi) to rate appropriateness of imaging and treatment procedures by the panel. In those instances where evidence is lacking or not definitive, expert opinion may be used to recommend imaging or treatment. RESULTS: From this process, 5 unique clinical variants were developed. These scenarios pertained to options of adjuvant radiation therapy and chemotherapy, methods of delivery of radiotherapy to optimize target volume coverage while simultaneously minimizing radiation exposure of adjacent healthy organs, and recommendations for patient follow-up care. Group members reached consensus of topic ratings in descending order of importance. A risk assessment breakdown was established to highlight the most likely indications for adjuvant treatment(s). CONCLUSION: This assembly by the ACR of physicians involved in the management of patients with early stage cervical cancer was able to describe appropriateness criteria to aid other practitioners in selecting reasonable implementation of postoperative therapies and subsequent surveillance studies. These guidelines await further validation and refinement by both current and future prospectively randomized clinical studies regarding this patient population.

Role of Stereotactic Body Radiation Therapy Before Orthotopic Liver Transplantation: Retrospective Evaluation of Pathologic Response and Outcomes.

PURPOSE: To analyze the results of stereotactic body radiation therapy (SBRT) in patients with early-stage, localized hepatocellular carcinoma who underwent definitive orthotopic liver transplantation (OLT). METHODS AND MATERIALS: The subjects of this retrospective report are 38 patients diagnosed with hepatocellular carcinoma who underwent SBRT per institutional phase 1 to 2 eligibility criteria, before definitive OLT. Pre-OLT radiographs were compared with pathologic gold standard. Analysis of treatment failures and deaths was undertaken. RESULTS: With median follow-up of 4.8 years from OLT, 9 of 38 patients (24%) recurred, whereas 10 of 38 patients (26%) died. Kaplan-Meier estimates of 3-year overall survival and disease-free survival are 77% and 74%, respectively. Sum longest dimension of tumors was significantly associated with disease-free survival (hazard ratio 1.93, P=.026). Pathologic response rate (complete plus partial response) was 68%. Radiographic scoring criteria performed poorly; modified Response Evaluation Criteria in Solid Tumors produced highest concordance (κ = 0.224). Explants revealed viable tumor in 74% of evaluable patients. Treatment failures had statistically larger sum longest dimension of tumors (4.0 cm vs 2.8 cm, P=.014) and non-statistically significant higher rates of lymphovascular space invasion (44% vs 17%), cT2 disease (44% vs 21%), ≥pT2 disease (67% vs 34%), multifocal tumors at time of SBRT (44% vs 21%), and less robust mean α-fetoprotein response (-25 IU/mL vs -162 IU/mL). CONCLUSIONS: Stereotactic body radiation therapy before to OLT is a well-tolerated treatment providing 68% pathologic response, though 74% of explants ultimately contained viable tumor. Radiographic response criteria poorly approximate pathology. Our data suggest further stratification of patients according to initial disease burden and treatment response.

ACR appropriateness Criteria® advanced stage endometrial cancer.

OBJECTIVES: Patients with advanced stage endometrial carcinoma constitute a heterogeneous group of patients with different stages, tumor histologic types, and involved sites. Hysterectomy, bilateral salpingo-ophorectomy, and surgical staging are the cornerstone of surgical management in these patients. The optimal adjuvant therapy is yet to be established. An expert panel was convened to reach consensus on the most appropriate management options in this group of patients. METHODS: The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed every 3 years by a multidisciplinary expert panel. The guideline development and review include an extensive analysis of current medical literature from peer-reviewed journals and the application of a well-established consensus methodology (modified Delphi) to rate the appropriateness of imaging and treatment procedures by the panel. In those instances where evidence is lacking or not definitive, expert opinion may be used to recommend imaging or treatment. RESULTS: Four clinical variants were developed to address common scenarios in the management of women with advanced-stage endometrial carcinoma. Group members reached consensus on the appropriateness of specific evaluation and treatment approaches with numerical ratings. CONCLUSIONS: In combining available medical literature and expert opinions, this manuscript may serve as an aid for other practitioners in the appropriate management of women with advanced-stage endometrial carcinoma.

ACR Appropriateness Criteria® management of locoregionally advanced squamous cell carcinoma of the vulva.

OBJECTIVES: Locoregionally advanced vulvar cancer (LRAVC) is a rare disease that presents many challenging medical decisions. An expert panel was convened to reach consensus on the most appropriate pretreatment assessment and therapeutic interventions in LRAVC patients. METHODS: The American College of Radiology Appropriateness Criteria are evidenced-based guidelines for specific clinical conditions that are reviewed every 2 years by a multidisciplinary expert panel. The guideline development and review include an extensive analysis of current medical literature from peer-reviewed journal and the application of a well-established consensus methodology (modified Delphi) to rate appropriateness of imaging and treatment procedures by the panel. In those instances where evidence is lacking or not definitive, expert opinion may be used to formulate recommendations. RESULTS: Three clinical variants were developed to address common scenarios in the management of LRAVC. Group members reached consensus on the appropriateness of specific evaluation and treatment approaches, with numerical ratings and descriptive commentary. CONCLUSIONS: In combining available medical literature and expert opinion, this manuscript may serve as an aid for other practitioners in the appropriate management of patients with LRAVC.

ACR Appropriateness Criteria® pretreatment planning of invasive cancer of the cervix.

The prognosis of cervical cancer is linked to lymph node involvement, and this is predicted clinically and pathologically by the stage of the disease, as well as the volume and grade of the tumor. Staging of cervical cancer based on International Federation of Gynecology and Obstetrics (FIGO) staging uses physical examination, cystoscopy, proctoscopy, intravenous urography, and barium enema. It does not include CT or MRI. Evaluation of the parametrium is limited in FIGO staging, and lymph node metastasis, an important prognostic factor, is not included in FIGO staging. The most important role for imaging is to distinguish stages Ia, Ib, and IIa disease treated with surgery from advanced disease treated with radiation therapy with or without chemotherapy. This article reviews the current role of imaging in pretreatment planning of invasive cervical cancer. The ACR Appropriateness Criteria(®) are evidence-based guidelines for specific clinical conditions that are reviewed every 2 years by a multidisciplinary expert panel. The guideline development and review include an extensive analysis of current medical literature from peer-reviewed journals and the application of a well-established consensus methodology (modified Delphi) to rate the appropriateness of imaging and treatment procedures by the panel. In those instances in which evidence is lacking or not definitive, expert opinion may be used to recommend imaging or treatment.

ACR appropriateness Criteria® pretreatment evaluation and follow-up of endometrial cancer of the uterus.

Endometrial cancer is one of the common malignancies in the female genital tract. Imaging in pretreatment evaluation may play an important role in an assessment of morphological prognostic factors including tumor size, depth of myometrial invasion, endocervical extent, and lymph node status. Imaging is also useful in posttreatment evaluation of patients with clinically suspected recurrence. Various modalities including MRI, CT ultrasound and FDG PET-CT-CT have been used for evaluation of the endometrial cancer in both before and after treatment settings. Literature on the indications and usefulness of these imaging studies for endometrial cancer is reviewed.

Treatment of anal carcinoma in immune-compromised patients.

BACKGROUND: Immune-compromised populations show an increased incidence of anogenital tract neoplasms. This study was undertaken to evaluate local control (LC), overall survival (OS) and toxicity in immune-compromised patients with anal carcinoma treated with radiotherapy with or without chemotherapy. METHODS: We identified 25 patients with anal carcinoma and human immunodeficiency virus (HIV) infection or history of solid-organ transplant on chronic medical immune-suppression. Median age and follow-up were 44 years and 26 months respectively. AJCC T-stages were Tis (4%), T1 (8%), T2 (58%) and T3 (29%). N-stages were N0 (79%), N1 (4%), N2 (13%) and N3 (4%). One patient had metastatic disease at diagnosis. Seventy-five percent received concurrent chemoradiotherapy. Median radiation dose to the primary tumour was 50 Gy. RESULTS: One-, 3- and 5-year LC without salvage therapy was 87%, 87% and 70% respectively. One-, 3- and 5-year actuarial OS was 96%, 73% and 61% respectively. One-, 3- and 5-year OS was 100% for treatment time (TT) <50 days and 57%, 38% and 0% for TT > or =50 days (p=0.0009). All patients had acute grade 2-3 skin toxicity. Acute grade 3-4 gastrointestinal (GI), genitourinary (GU) and haematological toxicity occurred in 8%, 0% and 38%. Late grade 3-4 skin, GI and GU toxicity occurred in 8%, 4% and 0%. CONCLUSIONS: Most HIV-positive and organ transplant patients receiving radiotherapy with or without chemotherapy experience acute toxicity but few have chronic complications. T-stage and CD4 level in HIV-positive patients predict for LC. T-stage and TT predict for OS.
