    Full Text Available Basal cell carcinoma (BCC remains the most common form of nonmelanoma skin cancer (NMSC in Caucasians, with perhaps as many as 2 million new cases expected to occur in the United States in 2010. Many treatment options, including surgical interventions and nonsurgical alternatives, have been utilized to treat BCC. In this paper, two non-surgical options, imiquimod therapy and photodynamic therapy (PDT, will be discussed. Both modalities have demonstrated acceptable disease control rates, cosmetically superior outcomes, and short-term cost-effectiveness. Further studies evaluating long-term cure rates and long-term cost effectiveness of imiquimod therapy and PDT are needed.

    Family physicians are regularly faced with identifying, treating, and counseling patients with skin cancers. Nonmelanoma skin cancer, which encompasses basal cell and squamous cell carcinoma, is the most common cancer in the United States. Ultraviolet B exposure is a significant factor in the development of basal cell and squamous cell carcinoma. The use of tanning beds is associated with a 1.5-fold increase in the risk of basal cell carcinoma and a 2.5-fold increase in the risk of squamous cell carcinoma. Routine screening for skin cancer is controversial. The U.S. Preventive Services Task Force cites insufficient evidence to recommend for or against routine whole-body skin examination to screen for skin cancer. Basal cell carcinoma most commonly appears as a pearly white, dome-shaped papule with prominent telangiectatic surface vessels. Squamous cell carcinoma most commonly appears as a firm, smooth, or hyperkeratotic papule or plaque, often with central ulceration. Initial tissue sampling for diagnosis involves a shave technique if the lesion is raised, or a 2- to 4-mm punch biopsy of the most abnormal-appearing area of skin. Mohs micrographic surgery has the lowest recurrence rate among treatments, but is best considered for large, high-risk tumors. Smaller, lower-risk tumors may be treated with surgical excision, electrodesiccation and curettage, or cryotherapy. Topical imiquimod and fluorouracil are also potential, but less supported, treatments. Although there are no clear guidelines for follow-up after an index nonmelanoma skin cancer, monitoring for recurrence is prudent because the risk of subsequent skin cancer is 35 percent at three years and 50 percent at five years.

    The purpose of this study was to investigate the clinical findings, treatment, and outcome of patients with glassy cell carcinoma of cervix. We reviewed all cases of glassy cell carcinoma of the uterine cervix confirmed and treated at the Dongsan Medical Center, Keimyung University, between January 1993 and December 2005. There were 7 cases with histopathologically confirmed gassy cell carcinoma. A tumor was diagnosed as glassy cell carcinoma if over 50% of the tumor cell type displayed glassy cell features. Six patients with stage IB had radical hysterectomy and bilateral pelvic node dissection, and 2 of them received adjuvant external pelvic irradiation with concurrent chemotherapy. Remaining one patient with stage IIA had curative concurrent chemoradiotherapy with external pelvic irradiation and brachytherapy. There were 7 patients diagnosed as glassy cell carcinoma among the 3,745 (0.2%) patients of carcinoma of uterine cervix. The mean age of 7 patients was 44 years with range of 35 to 53 years of age. The most frequent symptom was vaginal bleeding (86%). By the punch biopsy undertaken before treatment of 7 cases, 2 only cases could diagnose as glassy cell carcinoma of uterine cervix, but remaining of them confirmed by surgical pathological examination. The mean follow up duration was 73 months with range of 13 to 150 months. All 7 patients were alive without disease after treatment. Glassy cell carcinoma of the uterine cervix is a distinct clinicopathologic entity that demonstrates an aggressive biologic behavior. However for early-stage disease, we may have more favorable clinical outcome with radical surgery followed by chemoradiotherapy

    Vismodegib is a first-in-class agent targeting the hedgehog signaling pathway for treatment of patients with locally advanced basal cell carcinoma (BCC) and metastatic BCC. There have been concerns about the development of squamous cell carcinoma (SCC) in patients treated with this drug. We sought to determine whether treatment with vismodegib is associated with an increase in the risk of cutaneous SCC. In this retrospective cohort study, patients treated with vismodegib as part of phase I and II clinical studies were compared with participants from the University of California, San Francisco, Nonmelanoma Skin Cancer Cohort who received standard therapy for primary BCC. In total, 1675 patients were included in the analysis, and the development of SCC after vismodegib exposure was assessed. The use of vismodegib was not associated with an increased risk of subsequent development of SCC (adjusted hazard ratio, 0.57; 95% confidence interval, 0.28-1.16). Covariates including age, sex, history of previous nonmelanoma skin cancer, and number of visits per year were significantly associated with the development of SCC. A limitation of the study was that a historic control cohort was used as a comparator. Vismodegib was not associated with an increased risk of subsequent SCC when compared with standard surgical treatment of BCC. Copyright © 2017 American Academy of Dermatology, Inc.

    Conclusion: Both primary surgery and RT/CRT organ preservation are effective treatments for tonsillar SCC. Single modality treatment, either surgery or RT/CRT, can typically be provided for stage I–II diseases. Although RT/CRT organ preservation is used more frequently for stage III–IV tonsillar SCC in recent years, primary surgery combined with adjuvant therapy still achieves equivalent outcomes. Multidisciplinary pretreatment counseling and the facilities and personnel available are therefore important for decision-making. In addition, if RT/CRT organ preservation is selected as the primary treatment, tumor tonsillectomy is not indicated.

    For most cutaneous basal cell and squamous cell carcinomas (nonmelanoma skin cancers [NMSC]) data are insufficient to permit evidence-based choices among treatments. To compare tumor recurrence after treatments, we conducted a prospective cohort study of consecutive patients with primary NMSC treated with the most common treatments in two practices in 1999–2000. Recurrence was determined from medical records by observers blinded to treatment type. 24.3% of tumors (N=361) were treated with destruction with electrodessication / curettage, 38.3% (N=571) with excision, and 37.4% (N=556) with histologically-guided serial excision (Mohs surgery). Follow-up was available for 1174 patients with 1488 tumors (93.8%) at median 7.4 years; overall 5-year tumor recurrence rate [95% Confidence Interval] was 3.3% [2.3, 4.4]. Unadjusted recurrence rates did not differ after treatments: 4.9% [2.3, 7.4] after destruction, 3.5% [1.8, 5.2] after excision, and 2.1% [0.6, 3.5] after Mohs surgery (P=0.26), and no difference was seen after adjustment for risk factors. In tumors treated only with excision or Mohs surgery, the hazard of recurrence was not significantly different, even after adjustment for propensity for treatment with Mohs surgery. These data indicate that common treatments for NMSC were at least 95% effective, and further studies are needed to guide therapeutic choices for different clinical subgroups. PMID:23190903

This breakthrough in science led to the development of a variety of small molecules inhibiting the VEGF-dependent angiogenic pathway, such as sunitinib and sorafenib. These agents prolong overall and progression-free survival, respectively. The result was the development of robust front-line therapies which ultimately fail and are associated with disease progression. In this setting, there existed an unmet need for developing second-line therapies for patients with refractory metastatic renal cell carcinoma (MRCC. Everolimus (RAD 001 is an oral inhibitor of the mammalian target of rapamycin (mTOR pathway. The double-blind, randomized, placebo-controlled phase III trial of everolimus (RECORD-1 conducted in MRCC patients after progression on sunitinib or sorafenib, or both, demonstrated a progression-free survival benefit favoring the study drug (4.9 months vs 1.9 months, HR 0.33, 95% CI 0.25 to 0.43, P ≤ 0 0.001. Everolimus thus established itself as a standard of care in the second-line setting for patients with MRCC who have failed treatment with VEGF receptor inhibitors.Keywords: mTOR inhibitor, mammalian target of rapamycin inhibitor, signal transduction inhibitor, renal cell carcinoma, targeted therapy

    To evaluate the early clinical experience associated with radiofrequency (RF) ablation in patients with renal cell carcinoma (RCC). The RF ablation treatment was performed on 17 tumors from 16 patients (mean age, 60.5 years; range, 43 73 years) with RCC. The treatment indications were localized, solid renal mass, comorbidities, high operation risk, and refusal to perform surgery. All tumors were treated by a percutaneous CT (n = 10), followed by an US-guided (n = 2), laparoscopy-assisted US (n = 2), and an open (n = 2) RF ablation. Furthermore, patients underwent a follow- up CT at one day, one week, one month, three and six months, and then every six months from the onset of treatment. We evaluated the technical success, technical effectiveness, ablation zone, benign periablation enhancement, irregular peripheral enhancement, and complications. All 17 exophytic tumors (mean size, 2.2 cm; range, 1.1 5.0 cm) were completely ablated. Technical success and effectiveness was achieved in all cases and the mean follow-up period was 23.8 months (range, 17 33 months). A local recurrence was not detected in any of the cases; however, five patients developed complications as a result of treatment, including hematuria (n = 2), mild thermal injury of the psoas muscle (n = 1), mild hydronephrosis (n = 1), and fistula formation (n = 1). The RF ablation is an alternative treatment for exophytic RCCs and represents a promising treatment for some patients with small RCCs.

    Between 1979 and 1995, 153 patients were treated for squamous cell carcinoma of the oropharynx (except the posterior wall region). All patients had a minimum 2-year follow-up and no patient was lost to follow-up. The distribution according to primary site was as follows: base of tongue region, 41 lesions; tonsillar fossa region, 71 lesions; and anterior tonsillar pillar and soft palate region, 41 lesions. The T1 and T2 tumors treated with surgery or radiotherapy had control rates of 29/33 (88%) and 48/66 (73%), respectively. The base of the tongue and tonsillar fossa region had good local control rates in both surgery and radiotherapy. In the anterior tonsillar pillar and soft palate region, however, the initial control by radiotherapy and surgery was T1 and T2 of 8/ 21 (38%) and T1 and T2 of 8/9 (89%) respectively. The ultimate local control rate after surgical salvage was 25 (83%) of 30 patients. Surgical salvage was often successful for early lesions. Surgery is an effective form of treatment for carcinoma of the soft palate and tonsillar pillar. (author)

  18. Sunitinib malate for the treatment of renal cell carcinoma.

    Wood, Lori

    2012-06-01

    Over the past decade, a greater understanding into the molecular pathogenesis of renal cell carcinoma (RCC) has led to major advances in treatment options. Sunitinib is an oral, small-molecule, multi-targeted receptor tyrosine kinase inhibitor (TKI) that targets a number of receptors, including vascular endothelial growth factor receptors (VEGFR) and platelet-derived growth factor receptors (PDGFR). Sunitinib was one of the first targeted agents studied in metastatic RCC (mRCC) and is currently used worldwide in the management of mRCC. This drug evaluation addresses the preclinical and clinical development of sunitinib. It provides an in-depth discussion of the Phase II data that led to its approval in mRCC and the subsequent Phase III clinical trial comparing sunitinib to interferon-α. More recent data from the large international expanded access trial, in non-clear cell carcinoma patients, different dosing schedule studies and safety issues are also discussed. Finally, areas for the future use of sunitinib, including in the adjuvant setting, are reviewed. Since the FDA approved sunitinib for advanced RCC in January 2006, much more has been learned about its efficacy and tolerability. Over the past decade of its clinical use, it has become clear that expertise is required when prescribing sunitinib, in terms of maximizing dose, anticipating and managing side effects, and assessing responses. In the future, a better understanding of sunitinib's role compared with other VEGF TKIs and mTOR inhibitors, and in other roles such as the adjuvant setting or in non-clear cell pathology, will become evident.

    Basal cell carcinoma represents is most common tumor in fair-skinned individuals. In Germany, age-standardized incidence rates are 63 (women) and 80 (men) per 100,000 population per year. Early lesions may be difficult to diagnose merely on clinical grounds. Here, noninvasive diagnostic tools such as optical coherence tomography and confocal laser scanning microscopy may be helpful. The clinical diagnosis is usually confirmed by histology. Standard therapy consists of complete excision with thorough histological examination, either by means of micrographic surgery or, depending on tumor size and location as well as infiltration, using surgical margins of 3-5 mm or more. In particular, multiple basal cell carcinomas (such as in Gorlin-Goltz syndrome) and locally advanced as well as rarely also metastatic basal cell carcinoma may pose a therapeutic challenge. In superficial basal cell carcinoma, nonsurgical therapies such as photodynamic therapy or topical agents may be considered. In case of locally advanced or metastatic basal cell carcinoma, an interdisciplinary tumor board should issue therapeutic recommendations. These include radiation therapy as well as systemic therapy with a hedgehog inhibitor. © 2015 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons Ltd.

    2015-01-01

    Introduction: The involvement of the histone deacetylases (HDACs) family in tumor development and progression is well demonstrated. HDAC inhibitors (HDACis) constitute a novel, heterogeneous family of highly selective anticancer agents that inhibit HDACs and present significant antitumor activity in several human malignancies, including oral squamous cell carcinoma (OSCC). Areas covered: This review summarizes the current research on the anticancer activity of HDACis against OSCC. The review also presents the molecular mechanisms of HDACis action and the existing studies evaluating their utilization in combined therapies of OSCC. Expert opinion: The currently available data support evidence that HDACis may provide new therapeutic options against OSCC, decreasing treatment side effects and allowing a more conservative therapeutic approach. Future research should be focused on in vivo and clinical evaluation of their utilization as combined therapies or monotherapies. Before HDACis can be brought into clinical practice as treatment options for OSCC, further evaluation is needed to determine their optimal dosage, the appropriate duration of treatment and whether they should be used in combination or as stand-alone therapeutics.

    2014-05-30

    With an incidence of 70 to over 800 new cases per 100 000 persons per year, basal cell carcinoma (BCC) is a very common disease, accounting for about 80% of all cases of non-melanoma skin cancer. It very rarely metastasizes. A variety of treatments are available for the different subtypes and stages of BCC. This review is based on pertinent literature retrieved by a selective search in the Medline database, as well as the American Cancer Society guidelines on BCC and the German guidelines on BCC and skin cancer prevention. The gold standard of treatment is surgical excision with histological control of excision margins, which has a 5-year recurrence rate of less than 3% on the face. For superficial BCC, approved medications such as imiquimod (total remission rate, 82-90%) and topical 5-fluorouracil (80%) are available, as is photodynamic therapy (71-87%). Other ablative methods (laser, cryosurgery) are applicable in some cases. Radiotherapy is an alternative treatment for invasive, inoperable BCC, with 5-year tumor control rates of 89-96%. Recently, drugs that inhibit an intracellular signaling pathway have become available for the treatment of locally advanced or metastatic BCC. Phase I and II clinical trials revealed that vismodegib was associated with objective response rates of 30-55% and tumor control rates of 80-90%. This drug was approved on the basis of a non-randomized trial with no control arm. It has side effects ranging from muscle cramps (71%) and hair loss (65%) to taste disturbances (55%) and birth defects. The established, standard treatments are generally highly effective. Vismodegib is a newly approved treatment option for locally advanced BCC that is not amenable to either surgery or radiotherapy.

    To determine the cost of treatment of oropharyngeal squamous cell carcinoma (OP SCCA) with transoral surgery with concomitant neck dissection (TOS), TOS with adjuvant radiation therapy (TOS + RT), TOS with adjuvant chemoradiation therapy (TOS + CRT), and primary chemoradiation therapy (CRT). Case series. Two tertiary care teaching hospitals. Using the databases of 2 teaching hospitals, patients were identified who had OP SCCA treated with TOS, TOS + RT, TOS + CRT, and primary CRT in 2009 to 2010. Costs were analyzed from an institutional perspective looking at reimbursement. Patients with government payers and patients with private payers in each group were identified, and net revenue data obtained for the 3-month period from diagnosis were calculated and averaged for each group. Cost was defined as the reimbursement for all charges surrounding the 3-month episode of treatment. All revenue associated with inpatient and outpatient care, including pharmacy charges, was included. The mean cost of TOS (private payers/government payers) was $37,435/$15,664 (range, $22,486-$48,746/$13,325-$16,885). The mean cost of TOS + RT (private payers/government payers) was $74,484/$34,343 (range, $72,400-$84,825/$31,565-$40,810). The mean cost of TOS + CRT (private payers/government payers) was $191,780/$53,245 (range, $145,450-$217,220/$49,400-$58,325). The mean cost of CRT (private payers/government payers) was $198,285/$57,429 (range, $168,216-$298,945/$52,900-$59,545). An algorithm of transoral surgical treatment of OP SCCA with adjuvant treatment as indicated by pathology is more cost conscious than an algorithm of treatment of all OP SCCA with CRT.

    Survival time of the patients with bronchogenic small cell anaplastic cancer was studied. Combined treatment with six-drug combination chemotherapy ''METVFC'' (mitomycin C + cyclophosphamide + toyomycin + vincristine + 5-FU + cytosine arabinoside) and radiotherapy (5,000 rads in total) was given to 14 cases of limited disease of small cell carcinoma. Median survival was 8 months, one year and two year survival rates were 47% and 27%, respectively. Combined treatment with METVFC and small dose radiotherapy of 100 or 200 rads irradiation 4 hours before chemotherapy, followed by remission consolidation of 3,000 -- 4,000 rads radiotherapy, thereafter second line chemotherapy of ''COAM'' (cyclophosphamide + vincristine + ACNU + methotrexate) was given to 4 cases of limited disease of small cell carcinoma. All cases survived more than 1.5 years and two of them have retained complete remission more than 1.5 years. There are 6 cases with small cell carcinoma survived more than 3 years out of total 128 cases. They are all those of limited disease. They received combined treatment of chemotherapy and radiotherapy simultaneously or alternatively, followed by remission maintenance chemotherapy. One case of them died from cancer. Two cases died from another disease without lung cancer. Three cases survived healthy more than 3 to 8 years. In the limited disease, small cell carcinoma of the lung might be curable if the complete remission could continue more than three years. (author)

    A 3-yr-old male panther chameleon (Furcifer pardalis) presented with bilateral raised crusted skin lesions along the lateral body wall that were found to be carcinoma in situ and squamous cell carcinoma. Similar lesions later developed on the caudal body wall and tail. A subcutaneous implantable carboplatin bead was placed in the first squamous cell carcinoma lesion identified. Additional new lesions sampled were also found to be squamous cell carcinomas, and viral polymerase chain reaction was negative for papillomaviruses and herpesviruses. Significant skin loss would have resulted from excision of all the lesions, so treatment with only carboplatin beads was used. No adverse effects were observed. Lesions not excised that were treated with beads decreased in size. This is the first description of cutaneous squamous cell carcinoma and treatment with carboplatin implantable beads in a panther chameleon.

    Full Text Available The most important prognostic factors for clear cell carcinoma (CCC are clinical and morphological signs and clinical stage of the disease. Analyses of 5-year survival in patients with I stage of CCC is 69 %, in II stage – 55 %, in III stage – 14 % and in IV stage – 4 % patients. We analyzed distant results of treatment of 71 patients with CCC and of 25 patients with mixed malignant ovaries neoplasm with obligatory clear cell component taking into consideration main clinical and morphological sings of disease. On the base of performed reseal we revealed that morphological structure of the tumors and stage of the disease exerted heist influence on the exponent of survival of the patients with clear CCC ovaries neoplasm. Besides, there is a correlation between exponent of patients’ survival and radicalized of surgery, character of tumor growth, differentiation degree, cell anaplasia and mitotic activity of tumor cells.

    Angiogenesis is a critical process in the progression of advanced renal cell carcinoma. Agents targeting angiogenesis have played a primary role in the treatment of metastatic renal cell carcinoma. However, resistance to anti-angiogenesis therapy almost always occurs, and major progress has been made in understanding its underlying molecular mechanism. Axitinib and everolimus have been used extensively in patients whom have had disease progression after prior anti-angiogenesis therapy. Recently, several new agents have been shown to improve overall survival in comparison with everolimus. This review provides an in-depth summary of drugs employable in the clinical setting, the rationale to their use, and the studies conducted leading to their approval for use and provides perspective on the paradigm shift in the treatment of renal cell carcinoma. Highlighted are the newly approved agents cabozantinib, nivolumab, and lenvatinib for advanced renal cell carcinoma patients treated with prior anti-angiogenesis therapy.

    Full Text Available Objective  To evaluate the clinical efficacy, the immune function and follow-up observation of autologous dendritic cells (DCs combined with cytokine-induced killer (CIK cells in the treatment of metastatic renal cell carcinoma. Methods  Peripheral blood mononuclear cells (PBMCs were collected from 27 patients with metastatic renal cell carcinoma, and cultured in vitro to produce DCs and CIK cells. After sterility test, phenotypic characterization by flow cytometry and cell count, the produced DCs and CIK cells were then returned to the patient. DCs were given subcutaneously on day 7, 9, 11 and 13 respectively, after PBMCs collection, and CIK cells were given intravenously on day 11 and 13 respectively. This treatment regimen was repeated at a 3 months interval until the disease progresses. Clinical outcomes and immune function were recorded during the treatment period. Results  After DCs-CIK cells treatment, clinical efficacy showed an objective response rate (ORR of 37%, a disease control rate (DCR of 85% and 2 years overall survival rate of 81.5%. There were no significant changes of T cell subsets including CD3 +CD4+CD8–, CD3+CD4–CD8+, CD3+CD19–, CD3–CD19+, CD3–CD16+CD56+, CD3+CD16+CD56+, CD3+HLA-DR–, CD3+HLA-DR+, CD3+CD28+CD8+ and Th2 cells except CD3+CD4+CD25+ T cells (Treg cells and Th1 in peripheral blood between pre-and post-treatment. No serious adverse events were observed. Conclusion  DCs-CIK cells immunotherapy provides a safe and effective treatment approach for patients with metastatic renal cell carcinoma, and may improve the immunosuppression status and enhance the anti-tumor immunity without obvious adverse reaction.

    Epidermal squamous cell carcinoma is an extremely common type of cancer. Early tumors can be successfully treated by surgery, but recurrent disease is aggressive and resistant to therapy. Cisplatin is often used as a treatment, but the outcome is rarely satisfactory. For this reason new strategies are required. Sulforaphane is a diet-derived cancer prevention agent that is effective in suppressing tumor growth in animal models of skin cancer. We monitored the efficacy of sulforaphane and cisplatin as a combined therapy for squamous cell carcinoma. Both agents suppress cell proliferation, growth of cancer stem cell spheroids, matrigel invasion and migration of SCC-13 and HaCaT cells, and combination treatment is more efficient. In addition, SCC-13 cell derived cancer stem cells are more responsive to these agents than non-stem cancer cells. Both agents suppress tumor formation, but enhanced suppression is observed with combined treatment. Moreover, both agents reduce the number of tumor-resident cancer stem cells. SFN treatment of cultured cells or tumors increases apoptosis and p21 Cip1 level, and both agents increase tumor apoptosis. We suggest that combined therapy with sulforaphane and cisplatin is efficient in suppressing tumor formation and may be a treatment option for advanced epidermal squamous cell carcinoma. © 2017 Wiley Periodicals, Inc.

    Basal cell carcinoma (BCC) is the most common cancer in the US population affecting approximately 2.8 million people per year. Basal cell carcinomas are usually slow-growing and rarely metastasize, but they do cause localized tissue destruction, compromised function, and cosmetic disfigurement. To provide clinicians with guidelines for the management of BCC based on evidence from a comprehensive literature review, and consensus among the authors. An extensive review of the medical literature was conducted to evaluate the optimal treatment methods for cutaneous BCC, taking into consideration cure rates, recurrence rates, aesthetic and functional outcomes, and cost-effectiveness of the procedures. Surgical approaches provide the best outcomes for BCCs. Mohs micrographic surgery provides the highest cure rates while maximizing tissue preservation, maintenance of function, and cosmesis. Mohs micrographic surgery is an efficient and cost-effective procedure and remains the treatment of choice for high-risk BCCs and for those in cosmetically sensitive locations. Nonsurgical modalities may be used for low-risk BCCs when surgery is contraindicated or impractical, but the cure rates are lower.

    The efficacy of hypofractionated radiation protocol for feline facial squamous cell carcinoma was evaluated. Hypofractionated radiation therapy was applied to five cats showing single or multiple facial squamous cell carcinomas, in a total of ten histologically confirmed neoplastic lesions. Of the lesions, two were staged as T{sub 1}, four as T{sub 2}, two as T{sub 3}, and two as T{sub 4}. The animals were submitted to four radiation fractions from 7.6 to 10 grays each, with one week intervals. The equipment was a linear accelerator with electrons beam. The cats were evaluated weekly during the treatment and 30 and 60 days after the end of the radiation therapy. In this study, 40% of the lesions had complete remission, 40% partial remission, and 20% did not respond to the treatment. Response rates were lower as compared to other protocols previously used. However, hypofractionated radiation protocol was considered safe for feline facial squamous cell carcinoma. (author)

  20. The effect of wool hydrolysates on squamous cell carcinoma cells in vitro. Possible implications for cancer treatment.

    Tatsiana Damps

    Full Text Available Squamous cell carcinoma of the skin is the second most common cutaneous malignancy. Despite various available treatment methods and advances in noninvasive diagnostic techniques, the incidence of metastatic cutaneous squamous cell carcinoma is rising. Deficiency in effective preventive or treatment methods of transformed keratinocytes leads to necessity of searching for new anticancer agents. The present study aims to evaluate the possibility of using wool hydrolysates as such agents. Commercially available compounds such as 5-fluorouracil, ingenol mebutate, diclofenac sodium salt were also used in this study. The process of wool degradation was based on chemical pre-activation and enzymatic digestion of wool. The effect of mentioned compounds on cell viability of squamous carcinoma cell line and healthy keratinocytes was evaluated. The obtained data show a significantly stronger effect of selected wool hydrolysates compared to commercial compounds (p<0.05 on viability of cells. The wool hydrolysates decreased squamous cell carcinoma cells viability by up to 67% comparing to untreated cells. These results indicate bioactive properties of wool hydrolysates, which affect the viability of squamous carcinoma cells and decrease their number. We hypothesize that these agents may be used topically for treatment of transformed keratinocytes in actinic keratosis and invasive squamous skin cancer in humans.

    To evaluate the efficacy and safety of ultrasound (US)-guided percutaneous microwave ablation (MWA) for renal cell carcinoma (RCC) adjacent to renal sinus. This retrospective study included 41 patients who underwent US-guided percutaneous MWA of 41 RCCs adjacent to the renal sinus from April 2006 to December 2015. Contrast-enhanced images of US and computed tomography (CT) or magnetic resonance (MR) imaging were performed at pre-ablation and 1day, 1 month, 3 months, and every 6 months after ablation. Initial ablation success (IAS), disease-free survival (DFS), RCC-related survival (RRS), and overall survival (OS) were recorded at the follow-up visits. IAS was achieved in 92.7% (38/41) of the study subjects. The IAS significantly differed between patients with RCCs ≤4cm (100%, 29/29) and RCCs >4cm (75%, 9/12, p=0.021). During the median follow-up of 37.6 (range, 3.0-97.3) months, the estimated 1-, 3-, and 5-year DFS of patients with an initial tumor of ≤4cm were 100%, 89.7%, and 81.5%, respectively. The 1-, 3-, and 5-year RRS were 100%, 93.3%, and 93.3%, respectively. The 1-, 3-, and 5-year OS were 97.1%, 87.8%, and 83.6%, respectively. The multivariate analysis using the Cox proportional hazard model revealed no independent predictor of recurrence among all the variables. There were no MWA-related deaths among the study subjects. One patient developed a retroperitoneal abscess after ablation. US-guided percutaneous MWA appears to be a promising method for RCCs adjacent to renal sinus, especially for tumors ≤4cm.

    To describe the oncological characteristics and evolution of patients 65 years or older who underwent surgery for renal-cell carcinoma (RCC). We reviewed our prospectively maintained database of patients with RCC treated surgically. Those ≥ 65 years old were selected. We analyzed clinical and pathological characteristics as well as oncological and functional outcomes. Overall survival (OS) was estimated with the Kaplan-Meier method. Multivariate Cox-proportional hazards model was used to determine predictors of OS. A total of 156 elderly patients with mean age 72.0±5.5 years (range 65-92) and median follow-up of 33 months were included. Surgical approach was open radical nephrectomy in 114 (73.5%), laparoscopic radical nephrectomy in 13 (8.4%), open partial nephrectomy in 23 (14.2%) and laparoscopic partial nephrectomy in 6 (3.9%). Pathological stage was: Stage I, 71 (45.5%); Stage II, 27 (17.3%); Stage III, 48 (30.8%); and Stage IV, 10 (6.4%). Lastly, 51 (32.6%) patients died, 22 (43.1%) from cancer. The 5-year OS according to pathological stage was 77.6%, 71.9%, 45.1% and 11.7% for stage I, II, III and IV, respectively (P<.001). On multivariate analysis, pathological stage independently predicted OS (HR 1.96, 95% CI [1.36-2.84], P=.0003). The surgical management of RCC appears to be safe in properly selected patients 65 years or older. Pathological stage predicts survival in this population. Copyright © 2016 AEU.

    Surgical excision is the treatment of choice for basal cell carcinoma and micrographic surgery considered the gold standard, however not yet used routinely worldwide available, as in Brazil. Considering this, a previously developed treatment guideline, which the majority of tumors were treated by conventional technique (not micrographic) was tested. To establish the recurrence rate of basal cell carcinomas treated according to this guideline. Between May 2001 and July 2012, 919 basal cell carcinoma lesions in 410 patients were treated according to the proposed guideline. Patients were followed-up and reviewed between September 2013 and February 2014 for clinical, dermatoscopic and histopathologic detection of possible recurrences. After application of exclusion criteria, 520 lesions were studied, with 88.3% primary and 11.7% recurrent tumors. Histological pattern was indolent in 85.5%, 48.6% were located in high risk areas and 70% small tumors. Only 7.3% were treated by Mohs micrographic surgery. The recurrence rate, in an average follow-up period of 4.37 years, was 1.3% for primary and 1.63% for recurrent tumors. Study limitations: unicenter study, with all patients operated on by the same surgeon. The treatment guideline utilized seems a helpful guide for surgical treatment of basal cell carcinoma, especially if micrographic surgery is not available.

    Although basal cell carcinoma can be effectively managed through surgical excision, the most suitable surgical margins have not yet been fully determined. Furthermore, micrographic surgery is not readily available in many places around the world. A review of the literature regarding the surgical treatment of basal cell carcinoma was conducted in order to develop an algorithm for the surgical treatment of basal cell carcinoma that could help the choice of surgical technique and safety margins, considering the major factors that affect cure rates. Through this review, it was found that surgical margins of 4mm seem to be suitable for small, primary, well-defined basal cell carcinomas, although some good results can be achieved with smaller margins and the use of margin control surgical techniques. For treatment of high-risk and recurrent tumors, margins of 5-6 mm or margin control of the surgical excision is required. Previous treatment, histological subtype, site and size of the lesion should be considered in surgical planning because these factors have been proven to affect cure rates. Thus, considering these factors, the algorithm can be a useful tool, especially for places where micrographic surgery is not widely available. PMID:26131869

    Full Text Available BACKGROUND: Merkel cell carcinoma (MCC is a rare, very aggressive tumour. The pathogenesis remains unclear, but UV radiation, immunosuppression, and the presence of Merkel cell polyomavirus in the tumour genome appear to have a key role. Merkel cell carcinoma is a highly aggressive tumour that often has a lethal end. CAS REPORT: A patient at 93 years of age comes for an examination by a dermatologist due to a rapidly growing nodular tumour growth in the forehead area. A tumour was about 3 cm in size. It had no signs of basal-cell carcinoma, no arborising vascularisation, no pigmentations on dermoscopy. Clinically, an eventual Merkel cell carcinoma was considered for the patient, but other primary skin tumours had to be excluded, as well as the possibility that regarding the patient’s age, it may be a metastatic deposit. A skin biopsy was performed, as well as H-E examination and immunohistochemical analyses (positive CD56, positivity of neuroendocrine markers synaptophysin, chromogranin which were in favour of Merkel cell carcinoma of the skin. After setting the diagnosis, our patient was treated with therapy which led to a complete withdrawal of a tumour. However, after 3 months the patient had repeated relapse of a tumour at the same site on the forehead and metastases in the retroauricular lymph nodes bilaterally. It shows that the radiotherapy as monotherapy has a great effect on the removal of the tumour formation, but unfortunately, it has no impact on lesion recurrence. It is also compatible with the literature data. CONCLUSION: In many adult patients, as our case suggests, radiotherapy could be a good palliative treatment opportunity that should be considered, as well as a combination of radiation therapy with other oncologic therapeutic options.

    Full Text Available Objective: to improve the results of treatment in patients with squamous cell carcinoma of the anal canal, by creating a new combination treatment option, and to increase the rate of organ-sparing treatment.Subjects and methods. A new combination treatment option for squamous cell carcinoma of the anal canal was created, which involved a combination of radiotherapy and a multiple radio modification program (ultrahigh-frequency (UHF hyperthermia and local metronidazole (MZ injection and systemic polychemotherapy (RF patent No. 2427399 “A treatment option for squamous cell carcinoma of the anal canal” registered on 27 August 2011. To evaluate the created treatment option, the latter was analyzed in 157 patients with Т1–4N0–3M0 squamous cell carcinoma of the anal canal, who had been treated in 1990 to 2012. In 22 patients, radiotherapy was performed in combination with 3–5 sessions of local UHF hyperthermia (thermoradiotherapy (TRT; 88 patients received the latter in combination with polychemotherapy (thermoradiochemotherapy (TRCT; in addition to TRCT, 47 patients used MZ (TRCT + MZ.Results. In the TRT, TRCT, and TRCT + MZ groups, organ-sparing treatment was performed in 11 (50 %, 71 (80.7 %, and 44 (93.6 % patients, respectively. In these groups, the median follow-up was 18.6; 51.7, and 15.5 months, respectively. In the 3 groups, the three-year overall survival rates were 71.4; 90.0, and 96.3 % and the three-year relapse free survival rates were 46.7; 60.6, and 75.0 %, respectively.Conclusion. The created combination thermochemoradiotherapy involving a polymer combination with MZ (TRCT + MZ makes it possible to achieve organ-sparing treatment in 93.6 % of the patients and to slightly improve 3-year overall and relapse-free survival rates in patients with squamous cell carcinoma of the anal canal who have received organ-sparing treatment although there is only a tendency for statistical survival difference in this patient group.

    Full Text Available Audrey Bellesoeur, Edith Carton, Jerome Alexandre, Francois Goldwasser, Olivier Huillard Department of Medical Oncology, Hopital Cochin AP-HP, Paris, France Abstract: Since 2005, the approved first-line treatment of metastatic renal cell carcinoma consists in tyrosine kinase inhibitors (TKIs targeting the vascular endothelial growth factor receptors (VEGFRs. Axitinib is an oral second-generation TKI and a potent VEGFR inhibitor with a half maximal inhibitory concentration for the VEGF family receptors 10-fold lower than other TKIs. Axitinib activity in renal cell carcinoma (RCC patients has been studied in various settings and particularly as second-line treatment. In this setting, axitinib with clinically based dose escalation compared to sorafenib has demonstrated an improvement in progression-free survival in a randomized Phase III trial leading to US Food and Drug Administration approval. In the first-line setting, axitinib failed to demonstrate improved efficacy over sorafenib, but the field of RCC treatment is rapidly changing with novel TKIs as cabozantinib or the emergence of check point inhibitors as nivolumab and the place of axitinib in therapy is therefore challenged. In this review, we focus on axitinib pharmacological and clinical properties in RCC patients and discuss its place in the treatment of patients with RCC.

    An adult, female Malayan sun bear (Helarctos malayanus) was diagnosed with squamous cell carcinoma of the rostral mandible. Initial treatment included bilateral mandibulectomy rostral to the lingual frenulum followed by intra- and perilesional cisplatin injections. Recovery after the procedure was uneventful and the Malayan sun bear adapted well to a shortened mandible. Histopathology indicated incomplete surgical excision of the tumor; therefore, radiation therapy was instituted weekly for four treatments at 2 Gy in parallel opposed fields (total 4 Gy each treatment) with one additional cisplatin treatment. Two years after initial presentation, the animal showed no recurrence of neoplasia.

    To determine whether doxorubicin-piroxicam combination is safe and has activity against transitional cell carcinoma in dogs. Data was collected retrospectively from 34 dogs from two institutions over a 6-year period. Signalment, clinical presentation, treatment specifics, adverse events, response, progression-free survival and overall survival time were evaluated. Dogs received doxorubicin every 3 weeks and daily piroxicam; 17 dogs (50%) had surgery. Clinical presentations were those typically reported for transitional cell carcinoma. Mean number of doses administered was 3·5. Of the 23 dogs with measurable disease, 14 (60·5%) had stable disease, 7 (30·5%) had progressive disease and 2 (9%) a partial response. Adverse events were generally manageable, and gastrointestinal in origin; one dog died of treatment-related complications. Overall median progression-free survival and overall survival were 103 and 168 days, respectively. Cytoreductive surgery did not result in prolongation of progression-free survival, but significantly prolonged overall survival. All dogs but one died as a result of disease progression. Doxorubicin-piroxicam combination therapy is well-tolerated in dogs with transitional cell carcinoma although progression-free survival, overall survival and biological response rates appear modest. Combination with surgery appears to offer a survival advantage; however, this may reflect tumour location and volume. Prospective studies are necessary to compare activity of combination doxorubicin-piroxicam to currently applied therapies. © 2013 British Small Animal Veterinary Association.

    Full Text Available Recently, metastatic renal cell carcinoma (mRCC treatment has changed dramatically with the onset of new therapies against molecular targets replacing immunotherapy as standard treatment. We report the case of a 49-year-old patient with a moderately differentiated renal clear cell carcinoma without extracapsular extension who underwent radical nephrectomy. Eight months after surgery, he developed a thyroid metastasis which was also treated surgically with a hemithyroidectomy. Seventy-five months after nephrectomy, the patient presented an upper gastrointestinal bleeding due to a duodenal metastasis that infiltrates the head of the pancreas. The treatment applied was surgery by duodenopancreatectomy, with positive surgical margins in the pathologic study. In addition to this, the extension study showed lung metastases requiring initiation of systemic treatment with sunitinib. The patient presented an excellent response to treatment, showing complete clinical and radiological response at 5 months of treatment (RECIST criteria and a disease-free survival of 48 months until now, without evidence of toxicity. RCC has the potential to metastasize to almost any location, but thyroid and duodenal metastases in RCC are extremely rare. Moreover, this case also highlights the good responses that can be achieved in terms of disease-free survival, low toxicity and quality of life in this new era of therapies against molecular targets.

    Seven cases of basal cell carcinoma are reported in this paper. The incidence of this disease is two percent of all malignancies seen at the Miraj Medical Centre, Miraj, Maharashtra. There were five male and two female patients in this series. The youngest patient was 40 years old and the oldest 70 years. The average age of the patients was 57.3 years. All the cases in the series had lesions confined to the head and neck region. Radiation therapy was given to all the seven cases which was the primary form of treatment in five cases. In two cases surgical excision had been done and the growth in both the cases had recurred. Radiation therapy is considered more ideal and suitable in the treatment of basal cell carcinomas. (auth.)

    Spindle cell carcinoma (SCC) is a rare form of lung cancer representing 0.2 to 0.3% of all primary pulmonary malignancies. Even with combined surgery, chemotherapy, and radiation therapy, these tumors are associated with a poor prognosis and only 10% of patients survive 2 years after diagnosis. We describe a patient with an unresectable SCC who, following no response to conventional treatment with combined modality therapy, chose to medicate herself with daily doses of germanium obtained in a health food store. She noted prompt symptomatic improvement and remains clinically and radiographically free of disease 42 months after starting her alternative therapy.

    In humans, sex-determining region-Y (SRY) related high-mobility-group box 4 (SOX4) is linked to development and tumorigenesis. SOX4 is over-expressed in several cancers and has prognostic significance. This study evaluated whether SOX4 affects oncogenic behavior and chemoradiotherapy response in head and neck squamous cell carcinoma (HNSCC) cells, and documented the relationship between its expression and prognosis in oral squamous cell carcinoma (OSCC). We used small interfering RNA in HNSCC cells to evaluate the effect of SOX4 on cell proliferation, apoptosis, chemoradiation-induced apoptosis, invasion, and migration. SOX4 expression in OSCC tissues was investigated by immunohistochemistry. SOX4 knockdown (KO) decreased cell proliferation and induced apoptosis by activating caspases-3 and −7, and poly-ADP ribose polymerase and suppressing X-linked inhibitor of apoptosis protein in HNSCC cells; it also enhanced radiation/cisplatin-induced apoptosis; and suppressed tumor cell invasion and migration. Immunostaining showed SOX4 protein was significantly increased in OSCC tissues compared with adjacent normal mucosa. SOX4 expression was observed in 51.8 % of 85 OSCC tissues, and was significantly correlated with treatment failure (P = 0.032) and shorter overall survival (P = 0.036) in patients with OSCC. SOX4 may contribute to oncogenic phenotypes of HNSCC cells by promoting cell survival and causing chemoradioresistance. It could be a potential prognostic marker for OSCC.

    Sunitinib has recently become a standard treatment for metastatic renal cell carcinoma. However, various adverse events have been reported. We present the first case of clinically evident adrenal insufficiency during sunitinib therapy. A 72-year-old man began sunitinib therapy for bilateral lung and adrenal metastases of renal cell carcinoma. His adrenocorticotrophic hormone level was 93.6 pg/ml (7.2-63.3 pg/ml) before sunitinib treatment, indicating that subclinical adrenal insufficiency already existed. Fatigue, which is a frequently seen adverse effect of sunitinib treatment, emerged acutely on Day 24 of the second cycle. Adrenocorticotrophic hormone and free T4 were high and thyroid-stimulating hormone was suppressed. Under the clinical diagnosis of acute adrenal insufficiency with thyrotoxicosis, a low dose of steroid was administered. Fatigue was completely ameliorated by the following morning, although free T4 was still high and thyroid-stimulating hormone was still low. Therefore, hypermetabolism due to thyrotoxicosis unmasked adrenal insufficiency in our case. Physicians should be aware of this rare but potentially fatal complication when severe acute fatigue develops in patients with subclinical adrenal insufficiency.

    Human ovarian carcinoma parental and cisplatin-resistant cells were evaluated for their radiation sensitivity to high and low dose-rate irradiation and for the effectiveness of cisplatin in radiosensitization. The cisplatin resistant variant A2780 cp showed increased radiation resistance for both low dose-rate (LDRI) and high dose-rate irradiation. For cisplatin treatment for 1 h before and after HDRI there was radiosensitization in only the cisplatin-resistant variant. Concomitant cisplatin treatment during LDRI resulted in radiosensitization in both cell lines with dose-modifying factors ranging from 1.6 to 5.8. In this case greater radiosensitization was achieved in the parental cell line. In both cell lines the dose-modifying factors were larger when the cisplatin was refreshed every 6 h instead of 12 h during LDRI. These data show that cisplatin may be a very effective radiosensitizer when given during LDRI which is used in brachytherapy. (author)

    A 14-yr-old male puma (Puma concolor) was presented to the veterinary staff of the National Zoo in Malaysia for an auricular mass. Squamous cell carcinoma was diagnosed by histologic examination of a biopsy. Systemic administration of chemotherapy using vincristine (0.5 mg/m2 i.v. q. 7 days for six treatments) and prednisolone (2 mg/kg i.m. q. 72 hr x 7 days) caused side effects of vomiting, weight loss, and alopecia and did not improve the size or appearance of the tumor. Intralesional vincristine injections (0.2 mg q. 7 days for two treatments) and prednisolone (2 mg/kg i.m. q. 72 hr x 15 days) were administered, resulting in complete tumor regression after 14 days of treatment.

    Objective: To investigate the clinical characteristics and treatment of primary parotid squamous cell carcinoma through 16 patients. Methods: Sixteen such patients treated in our hospital from 1984 to 2005 were analyzed retrospectively. There were T1 2 patients, T2 and T3 5 patients each and T4 4. Ten patients had NO, and 6 N + lesions. Six patients were treated by monotherapy, ie-mono group (surgery alone or radiotherapy alone), the other 10 patients by surgery combined with postoperative radiotherapy. Results: The overall neck metastastic lymph nodes was observed in 12 patients (75%). The 3- and 5-year local control, overall survival and disease-free survival for the whole group was 45% and 30%, 58% and 58%; 36% and 27%, respectively. The 5-year survival for T1-T2 and T3-T4 patients was 100% and 29% (χ 2 =4.50, P=0.034), respectively. The 3-year overall survival of NO and N + patients was 80%, and 20% (χ 2 =8.70, P=0.003), with a disease-free survival of 54% and 0 (χ 2 =9.83, P=0.002), respectively. Conclusions: The choice of suitable treatment for locally advanced primary parotid squamous cell carcinoma is surgery plus postoperative radiotherapy. Prophylactic ipsilateral neck irradiation is necessary e- ven for N0 patients for the sake of high risk of neck node metastasis. (authors)

    In Canada, there is no formal process for registering nonmelanoma skin cancer (NMSC); thus, the epidemiology, treatment practices, and associated health costs are not well known. To investigate trends in new cases of skin cancer, treatment practices, and health care costs in New Brunswick, Canada. Data were extracted from the Provincial Cancer Registry and New Brunswick administrative health databases for 2002-2010. New cases: Basal Cell Carcinoma (BCC) was the most common skin cancer diagnosed, and incidence rates significantly increased between 1992 and 2010.Treatment practice: Dermatologists managed the majority (45%) of the overall skin cancer treatments.Health care costs: NMSC accounted for ∼80% of the health care costs for skin cancer and was dominated by BCC. Development of best practice treatment guidelines for NMSC in New Brunswick would improve future health care efficiencies, and standard protocols for registering new cases of NMSC in Canada would strengthen surveillance and reporting capacity.

    The hedgehog (Hh) signaling pathway has been identified as important to normal embryonic development in living organisms and it is implicated in processes including cell proliferation, differentiation and tissue patterning. Aberrant Hh pathway has been involved in the pathogenesis and chemotherapy resistance of different solid and hematologic malignancies. Basal cell carcinoma (BCC) and medulloblastoma are two well-recognized cancers with mutations in components of the Hh pathway. Vismodegib has recently approved as the first inhibitor of one of the components of the Hh pathway (smoothened). This review attempts to provide current data on the molecular pathways involved in the development of BCC and the therapeutic options available for the treatment of locally advanced and metastatic BCC, and the new targeted therapies in development.

    Patients with head and neck cancer often suffer from malnutrition. This study aims to investigate the influence of body mass index (BMI) on the prognosis of laryngeal squamous cell carcinoma (LSCC). A total of 473 patients with LSCC initially treated at Sun Yat-sen University Cancer Center between January 2005 and July 2009 were retrospectively reviewed. Survival analysis was performed by the Kaplan-Meier method and Cox regression model. Low BMI before treatment was significantly associated with poor overall survival in patients with LSCC (P<0.001). BMI was an independent prognostic factor for patients with LSCC. Leanness before treatment was associated with poor prognosis in patients with LSCC. Good nutritional status is favorable to improve survival in patients with LSCC

    Basal cell carcinoma (BCC) is the most common skin cancer worldwide. Most occur on the head and neck, where cosmetic and functional outcomes are critical. BCC can be locally destructive if not diagnosed early and treated appropriately. Surgery is the treatment of choice for the majority of high-risk lesions. Aggressive, recurrent or unresectable tumors can be difficult to manage. Until recently, no approved systemic therapy was available for locally advanced or metastatic BCC inappropriate for surgery or radiotherapy. Vismodegib provides a systemic treatment option. However, a consensus definition of advanced BCC is lacking. A multidisciplinary panel with expertise in oncology, dermatology, dermatologic surgery and radiation oncology proposes a consensus definition based on published evidence and clinical experience.

While rare, locally advanced BCCs that can no longer be controlled with surgery and/or radiation, and metastatic BCCs do occur and can be associated with significant morbidity and mortality. Vismodegib (GDC-0449, a smoothened inhibitor targeted at the hedgehog pathway, is the first US Food and Drug Association (FDA-approved agent in the treatment of locally advanced, unresectable, and metastatic BCCs. This class of agents appears to be changing the survival rates in advanced BCC patients, but appropriate patient selection and monitoring are important. Multidisciplinary assessments are essential for the optimal care and management of these patients. For some patients with locally advanced BCC, treatment with a hedgehog inhibitor may eliminate the need for an excessively disfiguring or morbid surgery.

    A captive 33-year-old male white rhinoceros with seasonal dermatitis was diagnosed with a malignant squamous cell carcinoma on the right flank. Staphylococcus aureus was cultured from the skin lesions. No fungal or yeast was isolated. The dermatitis was treated with a combination of oral antibiotics (trimethoprim-sulphadiazine) and topically with weekly chlorhexidine washes and a mixture of a zinc oxide, balsam peru and bismuth oxide cream. Under azaperone and butorphanol anaesthesia, the skin tumour was surgically removed. The tumour was excised with wide margins and allowed to heal by secondary intention as primary wound closure was not possible. A post-mortem performed 2 years later for an unrelated condition revealed no metastases or recurrence of the skin tumour. It was presumed that chronic irritation or trauma may have contributed to the development of the skin tumour. This is the first detailed report of the successful treatment of a squamous cell carcinoma not associated with the horn in a rhinoceros.

    This case study discusses the use of superficial radiotherapy (SXRT) in the treatment of recurrent conjunctival squamous cell carcinoma (SCC). Conjunctival SCC is often an aggressive cancer, with surgery the current standard of care. There is currently limited literature on alternative treatment options to treat conjunctival SCC recurrences that enable ocular function preservation. Furthermore, the use of SXRT in this setting is not well-reported. Technical feasibility, practical limitations and potential side effects of SXRT (in comparison to other treatment options) are discussed in this case study. This case describes a 62 years old male with limited treatment options following multiple recurrences of conjunctival SCC. He was prescribed a therapeutic SXRT dose of 48.4 Gy in 22 fractions (5 fractions/week). At 6-month follow-up, there was no evidence of residual or recurrent disease, or any significant objective or patient reported treatment induced side effects. This case study provides preliminary evidence for the potential application of SXRT for conjunctival SCC. The benefits reported in this case study warrant further investigation of the applicability of SXRT in a larger patient cohort, with the potential to provide patients with a less invasive treatment alternative for recurrent conjunctival SCC. © 2018 The Authors.

    Twenty-three patients with small cell carcinoma of the lung were examined with CT and conventional chest radiography before treatment, 19 after 3 courses of chemotherapy, before radiation therapy, and 8 after cessation of chemotherapy and radiation therapy. In most patients high abdominal CT was also employed. CT provided more information about the thoracic involvement than did conventional radiography in more than half of the cases. In 3 cases CT before irradiation demonstrated progression in the thorax, not visible at conventional radiography, and in 4 cases progression of extrathoracic metastases in spite of intrathoracic regression. After therapy, one case of progression in the thorax not seen at conventional radiography was demonstrated. With repeated CT examinations of the thorax and abdomen, progression/regression both intra- and extrathoracically is well demonstrated. (orig.)

    Small cell undifferentiated carcinoma (SmCC) of the gastrointestinal tract (GIT) is a rare and highly aggressive malignancy. To date, fewer than 1,000 cases have been reported, with an estimated prevalence of 0.1% to 1% of all gastrointestinal (GI) tumors. Data on the disease are scarce due to its rarity and the fact that most authors have focused on one site within the GIT. In light of the limited data and its perceived similarity to SmCC of the lung, the disease has usually been treated as the latter. Nevertheless, recent clinicopathologic and molecular data imply several differences between the two entities, questioning the extent to which extrapolations from one to the other can be made. We review the available data on GI SmCC with emphasis on outlining its clinicopathologic features and the recommended treatment approach.

    Full Text Available Background. Basal cell carcinoma (BCC is the most prevalent skin cancer. Because of its highly vascular characteristic, it is amendable to treatment with pulse dye laser (PDL. The goal of this study is to determine the safety and efficacy of PDL therapy for mostly facial BCCs. Materials and Methods. Sixteen men and thirteen women (29 total with 39 biopsy-proven BCCs were treated with 1–4 PDL (595 nm therapies at 2–4-week intervals. The treatment parameters included pulse energy of 15 J/cm 2, pulse length of 3 millisecond, with no dynamic cooling, and 7 mm spot size. The age of the patients was 30–90 years (mean 73 years. Response rates were evaluated by the clinical assessments with mean followup of 11 months. Results. Twenty-four patients with thirty-two tumors reached at least three months followup: 24/32 (75% tumors with complete resolution (mean 3 treatment sessions; 5/32 (16% tumors recurred; 3/32 (9% tumors with incomplete responses after four treatments. Minimal side effects and discomfort were experienced by the patients with PDL therapy. Conclusion. PDL is a safe, tolerable, and moderately effective method of treating various BCCs. The ideal niche and standardized settings for PDL treatment of BCCs are yet to be determined.

    Full Text Available Primary orbital squamous cell carcinoma is a rare entity. There is little published literature. We report a case of primary squamous cell carcinoma of the orbital soft tissues. Surgical resection offered the best treatment for the patient. Complete resection of the lesion was achieved. The patient received adjuvant radiotherapy due to the proximity of the lesion to the surgical margins. Surgical treatment is feasible and should be considered as part of the surgeon's arsenal. However, therapeutic decisions must be made on a case-by-case basis

    Although hedgehog inhibitor therapy (HHIT) is offered as isolated medical treatment for extensive basal cell carcinoma (BCC), there is little evidence on the use of HHIT before definitive surgical intervention. In order to better define the utilization of HHIT for extensive BCC, we evaluated the impact of neoadjuvant HHIT on the subsequent surgical resection and reconstruction. An IRB-approved, retrospective chart review was performed of patients who received HHIT as initial treatment for extensive BCC. Patients who discontinued HHIT and underwent surgical resection were included. Evaluation included BCC tumor response to HHIT, operative data, pathological data, radiation requirements, and evidence of tumor recurrence. Six patients were identified with tumors of the face/scalp (n = 4), trunk (n = 1) and upper extremity (n = 1). Hedgehog inhibitor therapy continued until tumors became unresponsive (n = 3, mean = 71 weeks) or side effects became intolerable (n = 3, mean = 31 weeks). In each case, a less extensive surgery was performed than estimated before HHIT. In 3 cases, significant bone resection was avoided. All resected specimens contained BCC. Four specimens exhibited clear margins. Postoperative radiation was performed in cases with positive margins (n = 2), and 1 patient experienced local recurrence. Length of follow-up was 5.7 to 11.8 months (mean = 8.23 months). Although HHIT was not curative for extensive BCC, HHIT can decrease the morbidity of surgical treatment and increase the likelihood of curative resection. For patients with extensive BCC, a combined neoadjuvant use of HHIT and surgical treatment should be considered.

Chemotherapy has been successfully integrated into first-line treatment programs, either during or prior to radiotherapy (RT – the cornerstone modality for local disease control of inoperable disease or when organ preservation is desired. Concomitant chemoradiotherapy (CCRT provides an absolute survival benefit when compared with other types of locoregional therapy that exclude chemotherapy. Nonetheless, distant metastases still represent the most common cause of treatment failure. Consequently, adding induction chemotherapy (ICT to definitive non-surgical local therapies with a curative intent has been vigorously explored in LA SCCHN. Recently, it has been shown that ICT using the combination of the taxane docetaxel with cisplatin–5-fluorouracil provides significant survival benefit over cisplatin–5-FU, when used before either definitive RT (TAX323 trial or carboplatin-based CCRT (TAX324 trial. Docetaxel is also being investigated in metastatic or recurrent (M/R disease, with promising initial results. It is very likely that the future management strategies of SCCHN will incorporate biologic agents as an add-on to docetaxel-containing schemas, administered either as ICT prior to CCRT in the LA setting or for the management of M/R disease.Keywords: chemoradiotherapy, chemotherapy, docetaxel, head and neck carcinoma, induction, locally

    Basal cell carcinoma (BCC) is the most common cancer in individuals with fair skin type (I–II) and steadily increasing in incidence (70% of skin malignancy). It is locally invasive but metastasis is usually very rare, with an estimated incidence of 0.0028%–0.55%. Conventional therapy is surgery, especially for the H region of the face and infiltrative lesions; in case of inoperable tumors, radiotherapy is a valid option. Recently, topical photodynamic therapy (PDT) has become an effective treatment in the management of superficial and small nodular BCC. PDT is a minimally invasive procedure that involves the administration of a photo-sensibilizing agent followed by irradiation at a pre-defined wavelength; this determines the creation of reactive oxygen species that specifically destroy target cells. The only major side effect is pain, reported by some patients during the irradiation. The high cure rate and excellent cosmetic outcome requires considering this possibility for the management of patients with both sporadic and hereditary BCC. In this article, an extensive review of the recent literature was made, in order to clarify the role of PDT as a possible alternative therapeutic option in the treatment of BCC. PMID:26426005

    The paradoxical rise in overall and cancer-specific mortality despite increased detection and treatment of renal cell carcinoma (RCC) is termed "treatment disconnect." We reassess this phenomenon by evaluating impact of missing data and rising incidence on mortality trends. Using Surveillance, Epidemiology, and End Results data, we identified patients with RCC diagnosis from 1973 to 2011. We estimated mortality rates by tumor size after accounting for lags from diagnosis to death using multiple imputations for missing data from 1983. Mortality rates were estimated irrespective of tumor size after adjustment for prior cumulative incidence using ridge regression. A total of 78,891 patients met inclusion criteria. Of 70,212 patients diagnosed since 1983, 10.4% had missing data. Significant attenuation in cancer-specific mortality was noted from 1983 to 2011 when comparing observed with imputed rates: Δobs0.05 versus Δimp0.10 (P=0.001, 7 cm tumors). Holding incidence of RCC constant to 2011 rates, temporal increase in overall mortality for all patients was attenuated (Pmortality trends. These findings were supported by assessment of mortality to incidence ratio trends. Missing data and rising incidence may contribute substantially to the "treatment disconnect" phenomenon when examining mortality rates in RCC using tumor registry data. Caution is advised when basing clinical and policy decisions on these data.

    The number of skin cancer patients, especially patients with basal cell carcinoma (BCC), is rapidly increasing. Resources available at dermato-oncology units have not increased proportionally, which affects the throughput time of patients. To assess the feasibility and safety of implementation of the one-stop-shop concept for the treatment of patients with BCC at a dermato-oncology unit. A pilot study on a one-stop-shop concept for BCC was performed to investigate procedure safety and patient satisfaction. Fresh frozen sections were used to diagnose the tumours, and subsequently treatment with photodynamic therapy or excision was performed on the same day. Time spent in the hospital was measured and questionnaires were used to evaluate patient satisfaction. Sixteen patients, who together had 19 tumours, were included. Diagnoses were made within a mean time of 100 min (range 27-160 min). The mean throughput time was 4 hours and 7 min (range 60-420 min). No complications were observed, and patient satisfaction was high. The one-stop-shop concept for the treatment of skin cancer patients is feasible and efficient for both patients and dermato-oncology units. Further research is necessary to investigate cost-effectiveness when larger patient groups are involved. © 2011 The Authors.

    Cutaneous basal cell carcinoma (BCC) is the most common human cancer and its incidence is rising worldwide. Ultraviolet radiation exposure, including tanning bed use, as well as host factors play a role in its development. The majority of cases are treated and cured with local therapies including surgery. Yet, the health care costs of diagnosis and treatment of BCCs in the US is substantial. In the United States, the cost of nonmelanoma skin cancer care in the Medicare population is estimated to be US$426 million per year. While rare, locally advanced BCCs that can no longer be controlled with surgery and/or radiation, and metastatic BCCs do occur and can be associated with significant morbidity and mortality. Vismodegib (GDC-0449), a smoothened inhibitor targeted at the hedgehog pathway, is the first US Food and Drug Association (FDA)-approved agent in the treatment of locally advanced, unresectable, and metastatic BCCs. This class of agents appears to be changing the survival rates in advanced BCC patients, but appropriate patient selection and monitoring are important. Multidisciplinary assessments are essential for the optimal care and management of these patients. For some patients with locally advanced BCC, treatment with a hedgehog inhibitor may eliminate the need for an excessively disfiguring or morbid surgery. PMID:26604681

    Renal cell carcinoma (RCC) is more common in renal transplant and dialysis patients than the general population. However, RCC in transplanted kidneys is rare, and treatment has previously consisted of nephrectomy with a return to dialysis. There has been recent interest in nephron-sparing procedures as a treatment option for RCC in allograft kidneys in an effort to retain allograft function. Four patients with RCC in allograft kidneys were treated with nephrectomy, partial nephrectomy, or radiofrequency ablation. All of the patients are without evidence of recurrence of RCC after treatment. We found nephron-sparing procedures to be reasonable initial options in managing incidental RCCs diagnosed in functioning allografts to maintain an improved quality of life and avoid immediate dialysis compared with radical nephrectomy of a functioning allograft. However, in non-functioning renal allografts, radical nephrectomy may allow for a higher chance of cure without the loss of transplant function. Consequently, radical nephrectomy should be utilized whenever the allograft is non-functioning and the patient's surgical risk is not prohibitive. © 2013 John Wiley & Sons A/S.

    The efficacy of radiation therapy for feline advanced cutaneous squamous cell carcinoma was evaluated. A full course radiation therapy protocol was applied to six cats showing single or multiple facial squamous cell carcinomas, in a total of seven histologically confirmed neoplastic lesions. Of the lesions, one was staged as T{sub 1}, and six as T{sub 4} according to WHO staging system of epidermal tumors. The animals were submitted to twelve radiation fractions of 4 Gy each, on a Monday-Wednesday-Friday schedule, and the equipment used was an orthovoltage unit. Energy used was 120 kV, 15 mA and 2 mm aluminum filter. The cats were evaluated during the treatment and 30 and 60 days after the end of the radiation therapy. In this study, 87% of the lesions had complete remission and 13% partial remission to the treatment. Side effects were considered mild according to Veterinary Radiation Therapy Oncology Group Toxicity criteria, and included erythema, epilation and rhinitis. Radiation Therapy was considered safe for feline cutaneous squamous cell carcinoma, leading to mild side effects and can represent a good therapeutic option. (author)

    Indocyanine green (ICG) is a near-IR fluorescent dye with a great potential for application as photosensitizer in topical photodynamic therapy (PDT) of skin diseases. Despite its merits, its use has been hampered by its high degradation rate. Therefore, in the current article, ICG was encapsulated in a vesicular colloidal nanocarrier (transfersomes), with the aim of enhancing its therapeutic efficacy. Transfersomes were characterized for their entrapment efficiency, particle size, zeta potential, morphology, in vitro release and histopathological effect on mice skin. A pilot clinical study was conducted to test its therapeutic potential for PDT of basal cell carcinoma (BCC). Transfersomal ICG displayed particle size (∼125 nm) and a negative zeta potential (∼-31 mV). Transfersomes were also able to sustain the release of ICG >2 h. Upon incorporation of transfersomal ICG in gel form, it was found to maintain the normal histology of mice skin post-irradiation with diode laser 820 nm. Moreover, ICG transfersomal PDT achieved 80% clearance rate for BCC patients with minimal pain reported during treatment. The previous findings suggest that transfersomal nanoencapsulated ICG is a promising treatment modality for BCC.

    To evaluate safety and efficacy of transarterial hepatic radioembolization treatment of patients with liver-dominant metastatic renal cell carcinoma (RCC). From July 2010 to December 2014, 18 patients with liver-dominant metastatic RCC were treated with yttrium-90 glass microsphere radioembolization. Retrospective review of medical records and imaging studies was performed to evaluate toxicities, treatment response, and overall survival. The median follow-up period from radioembolization treatment was 17.8 months (range, 3-54.4 months). Median overall survival from RCC diagnosis was 64 months (95% confidence interval [CI], 0-144.1 months), from diagnosis of liver metastasis was 29 months (95% CI, 7.2-50.8 months), and from radioembolization treatment was 22.8 months (95% CI, 13.2-32.3 months). After treatment, 10 patients reported grade 1 clinical toxicities, and 8 patients had grade 1 or 2 biochemical toxicities. The best radiographic responses of 17 patients who underwent contrast-enhanced cross-sectional imaging showed complete response in 16 patients and partial response in 1 patient evaluated by modified Response Evaluation Criteria in Solid Tumors (mRECIST) criteria. The last available imaging of these 17 patients demonstrated complete response in 14 patients, partial response in 1 patient, and progression of disease in 2 patients. Images of a patient who underwent noncontrast CT showed stable disease as best response and stable disease on the last available imaging evaluated by RECIST. Radioembolization is safe and effective and led to improved hepatic disease control and overall survival in patients with liver-dominant metastatic RCC. Copyright © 2016 SIR.

    Full Text Available Photodynamic therapy has shown promise in the treatment of early head and neck squamous cell carcinoma (SCC. In photodynamic therapy (PDT, a light sensitive drug (photosensitizer and visible light cause cancer cell death by the creation of singlet oxygen and free radicals, inciting an immune response, and vascular collapse. In this paper, we review several studies that demonstrate the effectiveness of PDT in the treatment of early stage SCC of the head and neck, with some showing a similar response rate to surgery. Two cases are presented to illustrate the effectiveness of PDT. Then, new advances are discussed including the discovery of STAT3 crosslinking as a potential biomarker for PDT response and interstitial PDT for locally advanced cancers.

    Full Text Available Background: Injury by the sting of Lesser weever fish (Trachinus vipera may lead to severe pain, edema or tissue necrosis. Cellular effects of the venom are still incompletely understood. Previous observations revealed that purified Lesser weever fish venom (LWFV induces suicidal death of erythrocytes and HCT116 human colon carcinoma cells. The present study addressed the effect of the venom on colon carcinoma cell toxicity, shape and migration both in p53+/+ and/or p53-/- conditions. Methods: Cells were exposed to medium without or with 500 µg/ ml LWFV. Cell shape, cell area and circularity were visualized and quantified by fluorescence microscopy. Cell volume, granularity and cells toxicity were assessed via the apoptotic parameters dissipation of mitochondrial inner transmembrane potential, phosphatidylserine surface exposure and cell membrane permeabilization were measured utilizing flow cytometry. Cell migration was evaluated using wound healing assay and two-dimensional migration assay. Results: LWFV treatment was followed by a marked change of cell shape and size, significant decrease of cell area and circularity, significant impairment of cell migration, as well as induction of apoptosis after long exposition. Conclusions: LWFV exposure leads to cell shrinkage, increased granularity, apoptosis and impairment of cell migration, effects presumably contributing to LWFV-induced tissue injury.

    Full Text Available Differentiating between clear cell neuroendocrine tumor (NET of the pancreas and renal cell carcinoma (RCC metastatic to the pancreas can be challenging in patients with von Hippel-Lindau disease (VHL. The clear cell features of both NET and RCC in VHL patients may lead to misdiagnosis, inaccurate staging, and alternative treatment. We present a patient in which this occurred. As clear cell NETs closely resembling metastatic RCC are distinctive neoplasms of VHL and metastatic RCC to the pancreas in the VHL population is rare, careful pathologic examination should be performed prior to subjecting patients to definitive surgical or medical therapies.

    Basal cell carcinoma (BCC) is the most frequent type of skin cancer in humans, with cumulative exposure to ultraviolet radiation as an important risk factor for development of illness such as severe solar burns during childhood or adolescence. BCC is mainly located on sun-exposed sites, head and neck being the areas of more incidences; although nose, eyelids and periorbitary tissue are unfavorable due to cosmetic results that BCC involves. Tumors can be classified as nodular, superficial, micronodular, morphea variety, infiltrating, pigmented, metatypic and fibroepithelioma of Pinkus. Several treatment options such as surgical and nonsurgical are available. The goal of treatment is complete excision of the tumor with preservation of surrounding structures in a way aesthetically acceptable. Mohs' micrographic surgery is the standard treatment for all nonmelanoma skin cancers. Orbital exenteration is also used for treatment of malignancies of ocular tissues, mainly squamous cell carcinoma, sebaceous cell carcinoma and BCC. The tissue beneath the surgical site can be left for second-intention granulation or covered with a cutaneous implant of partial thickness. The case of a 77-year-old patient is presented with BCC of inferior eyelid of 14 years' duration, formerly managed with radiotherapy; however, due to recurrent illness and invasion to the maxillary antrum, he needed supraestructure maxillectomy with left orbital exenteration.

    Full Text Available Abstract Several clinical trials to establish standard treatment modality for ovarian cancers included a high abundance of patients with serous histologic tumors, which were quite sensitive to platinum-based chemotherapy. On the other hand, ovarian tumor with rare histologic subtypes such as clear cell or mucinous tumors have been recognized to show chemo-resistant phenotype, leading to poorer prognosis. Especially, clear cell carcinoma of the ovary (CCC is a distinctive tumor, deriving from endometriosis or clear cell adenofibroma, and response rate to platinum-based therapy is extremely low. It was implied that complete surgical staging enabled us to distinguish a high risk group of recurrence in CCC patients whose disease was confined to the ovary (pT1M0; however, complete surgical staging procedures could not lead to improved survival. Moreover, the status of peritoneal cytology was recognized as an independent prognostic factor in early-staged CCC patients, even after complete surgical staging. In advanced cases with CCC, the patients with no residual tumor had significantly better survival than those with the tumor less than 1 cm or those with tumor diameter more than 1 cm. Therefore, the importance of achieving no macroscopic residual disease at primary surgery is so important compared with other histologic subtypes. On the other hand, many studies have shown that conventional platinum-based chemotherapy regimens yielded a poorer prognosis in patients with CCC than in patients with serous subtypes. The response rate by paclitaxel plus carboplatin (TC was slightly higher, ranging from 22% to 56%, which was not satisfactory enough. Another regimen for CCC tumors is now being explored: irinotecan plus cisplatin, and molecular targeting agents. In this review article, we discuss the surgical issues for early-staged and advanced CCC including possibility of fertility-sparing surgery, and the chemotherapy for CCC disease.

    Heparanase is an enzyme that cleaves heparan sulfate chains. Oligosaccharides generated by heparanase induce tumor progression. Basal cell carcinoma and squamous cell carcinoma comprise types of nonmelanoma skin cancer. Evaluate the glycosaminoglycans profile and expression of heparanase in two human cell lines established in culture, immortalized skin keratinocyte (HaCaT) and squamous cell carcinoma (A431) and also investigate the expression of heparanase in basal cell carcinoma, squamous cell carcinoma and eyelid skin of individuals not affected by the disease (control). Glycosaminoglycans were quantified by electrophoresis and indirect ELISA method. The heparanase expression was analyzed by quantitative RT-PCR (qRTPCR). The A431 strain showed significant increase in the sulfated glycosaminoglycans, increased heparanase expression and decreased hyaluronic acid, comparing to the HaCaT lineage. The mRNA expression of heparanase was significantly higher in Basal cell carcinoma and squamous cell carcinoma compared with control skin samples. It was also observed increased heparanase expression in squamous cell carcinoma compared to the Basal cell carcinoma. The glycosaminoglycans profile, as well as heparanase expression are different between HaCaT and A431 cell lines. The increased expression of heparanase in Basal cell carcinoma and squamous cell carcinoma suggests that this enzyme could be a marker for the diagnosis of such types of non-melanoma cancers, and may be useful as a target molecule for future alternative treatment.

    The evaluation of treatment outcomes and detection of prognostic factors after recurrence are very important for tailoring optimal therapies for individual patients with recurrent esophageal cancer. We reviewed 133 patients in whom esophageal squamous cell carcinoma (ESCC) recurred after curative surgery, and assessed recurrence patterns, treatment outcomes and prognostic factors. Recurrence in 57 (42.9%), 54 (40.6%) and 22 (16.5%) patients was locoregional, distant and combined, respectively. The median amounts of elapsed time until recurrence and median survival after recurrence for all patients were 9.1 and 8.3 months, respectively. Univariate and multivariate analyses selected time to recurrence (hazard ratio [HR], 0.98; 95% confidence interval [CI], 0.97-0.999; p = 0.04), recurrence location (locoregional vs. distant: HR, 1.63; 95% CI, 1.03-2.61; p = 0.04), number of organs with recurrence (1 vs. 3: HR, 3.49; 95% CI, 1.23-9.87; p = 0.02) and treatment after recurrence (best supportive care, [BSC] vs. chemotherapy [CT] or radiation therapy [RT]: HR, 0.37; 95% CI, 0.15-0.94; p = 0.04; BSC vs. CT and RT: HR, 0.50; 95% CI, 0.26-0.94; p = 0.03; BSC vs. HR, 0.47; 95% CI, 0.25-0.88; p = 0.02) as independent factors for survival after recurrence. Seventeen (12.8%) patients who had localized lymph node recurrence and lung oligometastasis and received multidisciplinary therapy after recurrence survived for >3 years thereafter. Despite the poor survival of patients with ESCC and early or distant recurrence or recurrence in ≥3 recurrent organs, appropriate multimodal therapies should be tailored for individual patients with recurrent ESCC.

    To report total cystectomy with reimplantation of the ureters in the proximal aspect of the vagina. Case report. An 11-year-old female spayed Vizsla with spontaneously occurring transitional cell carcinoma of the urethra and bladder. After initial treatment for transitional cell carcinoma of the bladder trigone with urethral stent placement and chemotherapy, the dog developed urinary incontinence 2 months after stent placement. Eleven months after initial diagnosis, the dog developed pulmonary metastasis and local progression, leading to bilateral ureteral dilatation. After palliative radiation, total cystectomy was performed. The owners elected euthanasia 442 days after original presentation and 92 days after total cystectomy. Euthanasia was unrelated to the surgical procedure, but was related to the primary disease. Total cystectomy is a technically feasible procedure that should be considered for the treatment of bladder cancer in dogs. © Copyright 2014 by The American College of Veterinary Surgeons.

    This study describes the experience with hypofractionated radiation therapy of squamous cell carcinoma and melanoma in dogs and cats. A total dose of 32-48 Gray (Gy) was delivered once a week in 8 Gy fractions. 34 animals in which a complete surgical excision was impossible were treated. There was no tumor detectable macroscopically in 14 patients at the beginning of radiation therapy. In 20 animals the median volume of the tumor was 9.9 cm3. The median survival times and the local tumor control of squamous cell carcinoma of the oral and nasal cavities and of the body are comparable to results which were reached with a Monday-Wednesday-Friday scheme. For the treatment of Melanoma the hypofractionated radiation therapy is first choice. There are no significant side effects. Late side effects did not occur. 88% of the owners are satisfied with this kind of treatment and would choose it again.

    Full Text Available Oral squamous cell carcinoma (OSCC is the most common epithelial malignancy affecting the oral cavity. The most common sites for the development are lateral surface of tongue and floor of mouth; the least common sites are soft palate, gingiva, and buccal mucosa. Gingival squamous cell carcinoma can mimic a multitude of oral lesions and enlargements, especially those of inflammatory origin. In addition, predisposing and presenting factors are different from those of other OSCCs. Careful examination as well as routine biopsy are crucial for accurate diagnosis.

    During recent decades radiotherapy is the basis, on which it is built a medical complex that is the first-line treatment of patients with squamous cell carcinoma of the anal canal. An increase of overall and disease-free survival and quality of life of patients with squamous cell carcinoma of the anal canal at the present stage of development of a comprehensive medical treatment is largely due to the improvement of technical equipment of radiotherapy departments of oncology clinics. The use of modem linear electron accelerators and systems of computer dosimetric planning to create a 3D program of isodose distribution, diagnostic devices (computed tomography and magnetic resonance imaging) as well as a number of other conditions permit accurate summarizing of proposed dose, reducing of absorbed dose to critical structures, diminishing unplanned interruptions in chemoradiotherapy course by means of modern technologies of conformal radiotherapy (3D CRT, IMRT, VMAT). The paper presents the preliminary results of a comprehensive medical treatment of 14 patients with squamous cell carcinoma of the anal canal.

    Full Text Available PURPOSE: To assess the current treatment of metastatic renal cell carcinoma, focusing on medical treatment options. MATERIAL AND METHODS: The most important recent publications have been selected after a literature search employing PubMed using the search terms: advanced and metastatic renal cell carcinoma, anti-angiogenesis drugs and systemic therapy; also significant meeting abstracts were consulted. RESULTS: Progress in understanding the molecular basis of renal cell carcinoma, especially related to genetics and angiogenesis, has been achieved mainly through of the study of von Hippel-Lindau disease. A great variety of active agents have been developed and tested in metastatic renal cell carcinoma (mRCC patients. New specific molecular therapies in metastatic disease are discussed. Sunitinib, Sorafenib and Bevacizumab increase the progression-free survival when compared to therapy with cytokines. Temsirolimus increases overall survival in high-risk patients. Growth factors and regulatory enzymes, such as carbonic anhydrase IX may be targets for future therapies. CONCLUSIONS: A broader knowledge of clear cell carcinoma molecular biology has permitted the beginning of a new era in mRCC therapy. Benefits of these novel agents in terms of progression-free and overall survival have been observed in patients with mRCC, and, in many cases, have become the standard of care. Sunitinib is now considered the new reference first-line treatment for mRCC. Despite all the progress in recent years, complete responses are still very rare. Currently, many important issues regarding the use of these agents in the management of metastatic renal cancer still need to be properly addressed.

    Full Text Available Objective: to assess the possibility of using the markers of acute kidney injury to predict the preoperative risk for the subsequent decline in glomerular filtration rate in different types of surgical treatment of renal cell carcinoma (RCC. Material and methods. 60 patients with histologically confirmed RCC T1-3M0N0 operated in the clinic of urology of Saratov State Medical University n.a. V. I. Razumovsky in the volume of nephrectomy or partial nephrectomy. Before surgery all patients underwent standard examination intended for patients with kidney tumors: ultrasound, MRI, excretory urography and dynamic renoscintigraphy, the perioperative values of serum creatinine and glomerular filtration rate were determined. Using the method of immuno-enzymatic analysis the concentrations of excreted with the urine NGAL and IL-18 in serum samples at the preoperative stage, after 5 days and after 1 month of postoperative follow-up were investigated. Differences in clinical data and clinical variables were compared by using Spearman rank correlations and t-test. Results. The determined parameters of acute kidney injury markers IL-18 and NGAL in the early postoperative period were increased in patients after open nephrectomy. Moreover, the correlation analysis according to the Spearman method revealed a strong significant correlation between the preoperative levels of IL-18 and GFR after surgery (r=1; p<0.05. Conclusion. Laparoscopic resection of RCC is the method of choice for surgical treatment of RCC. As a predictor of adverse prognosis, the level of IL-18 in serum may be used. Its increase correlates with a decline in renal function in the postoperative period, and according to some reports, IL-18 also is an independent predictor of adverse prognosis in patients with a localized RCC.

    The purpose of this study was to determine the efficacy and feasibility of full-dose preoperative radiation therapy (RT) in head and neck cancer presenting in the oral cavity, oro- and hypopharynx, within a single university hospital district. During a seven-year period, 1989 to 1995, 174 patients with squamous cell carcinoma (SCC) of the oral cavity (OC, 70% of all patients), oropharynx (OP, 15%) and hypopharynx (HP, 15%) were referred to Turku University Central Hospital. All patients were seen by a tumor board consisting of an ENT (ear-nose-throat) head and neck surgeon, a radiation oncologist and a dentist. Potentially curative treatment was given to 142 patients. Of these, 88 (62%) had preoperative RT, 6 (4%) postoperative RT, 34 (24%) definitive RT and 14 patients (10%) were treated with surgery only. The radiation dose was S50 Gy, averagely 64 Gy. The major endpoints of the study were local control, overall survival and major complications of the combined treatment. The 5-year relative survival rate (RSR) was 40% for all, and 43% for patients treated with curative intent. For these, the local control at 5 years was 60%; the disease-specific 5-year survival rate was 65% for the patients with lingual SCC, 45% for those with other oral tumor localizations, 64% for the oropharynx patients and 47% for those with tumor in their hypopharynx, while it was 55% for all patients. The preoperative radiotherapy was fairly well tolerated. Ten (7%) of the patients treated with curative intent suffered major complications, and four patients had evidence of osteoradionecrosis. With the exception of patients with early SCC the outcome remains rather poor in this group of cancer patients who often have marked co-morbidity. In our opinion, preoperative radiotherapy to a dose of 62-64 Gy can safely be given, and remains a feasible means to treat patients with oral, oropharyngeal or hypopharyngeal cancer

    Thirty eight cases of thymic carcinoma were treated in National Chest Hospitals between 1986 and 1995. These cases included 22 squamous cell carcinomas and 7 undifferentiated carcinomas. We then analyzed these 2 histologic types retrospectively and investigated the relationship between treatment and prognosis. We applied Masaoka`s clinical staging for thymoma. Squamous cell carcinoma consisted of 1 Stage I case, 6 Stage II cases, 7 Stage III cases, 3 Stage IVa cases, and 5 Stage IVb cases. In undifferentiated carcinoma, there were 3 Stage III cases, 1 Stage IVa case, and 3 Stage IVb cases. On interim analysis, the five year survival was 52% in squamous cell carcinomas and 35% in undifferentiated carcinomas. In Stage I and II cases, it was considered that good prognosis would be expected following surgery and postoperative radiation therapy. In Stage III or more advanced cases, it was suggested that induction therapy by concurrent chemoradiation followed by surgery would contribute to improvement of the results in treatment for thymic carcinoma.

    The histologic appearance, locoregional recurrence, and rate/site of metastases of spontaneous feline oral squamous cell carcinoma are similar to head and neck cancer in humans. A feasibility study of intratumoral Etanidazole, a hypoxic cell sensitizer, and radiation therapy were instituted in this model. Eleven cats with feline squamous cell carcinoma were treated with intratumoral Etanidazole and radiation therapy. Total Etanidazole doses were 1.5-24.0 gms/m2 (0.5-6.9 gms). The tumor partial response rate was 100% (11/11); the median volume regression was 70%. All cats have died as a result of tumor recurrence or tumor-related complications. Median survival was 116 days. Ten cats have been autopsied. Non-necrotic and necrotic tumor cells were identified at the treatment site in all cats. Pharmacokinetic studies were performed in six cats. Following intravenous infusion, the plasma elimination of the Etanidazole was biexponential. The systemic availability following intratumoral administration was 61.2 +/- 21.1%. Peak plasma Etanidazole levels were observed 14 minutes following intratumoral injection, after which elimination was biexponential. Thirty minutes following intratumoral Etanidazole administration, tumor Etanidazole levels were 62.8% of plasma levels. Feline squamous cell carcinoma appears to be a useful model of human head and neck cancer. Cats tolerate substantial doses of intratumoral and intravenous Etanidazole. Etanidazole and radiation therapy cause rapid regression, but not cure, of feline squamous cell carcinoma. There is a similarity between the intravenous kinetics of Etanidazole in humans and cats. Further studies in this model are planned

    The kinetics of a cancer-cell population under the effects of an antitumoral drug is a topic of particular interest. Its theoretical understanding, along with the improvement of experimental investigation techniques, can indeed play an important role in antitumoral therapies development. Starting from the analysis of flow-cytometric data, with the aid of computer simulation we are able to give a detailed, quantitative description of the main kinetic parameters describing drug action on cancer cells. In this paper we describe the main features of our investigation method, showing an application to Igrov-1 ovarian carcinoma cells treated with cisplatin. Intermitotic time of phases, cell-cycle delay, and block effects with consequent repair or cell mortality, in a wide range of drug doses and recovery times, are discussed and interesting information about cisplatin action is found.

    The effectiveness of neoadjuvant treatment (NT) prior to resection of squamous cell carcinoma of the esophagus (SCCE) in terms of prolonged survival has not been proven by randomized trials. Facing considerable financial expenses and with concerns regarding the consumption of the patient's remaining survival time, this study aims to provide rationales for pretreating resection candidates. From March 1986 to March 1999, patients undergoing resection for SCCE were documented prospectively. Since 1989, NT was offered to patients with mainly upper and middle third T3 or T4 tumors or T2 N1 stage who were fit for esophagectomy. Until 1993, NT consisted of chemotherapy. Since that time chemoradiation has also been applied. The parameters for expense and benefit of NT are costs, pretreatment time required, postoperative morbidity and mortality, clinical and histopathological response, and actuarial survival. Two hundred and three patients were treated, 170 by surgery alone and 33 by NT + surgery. Postoperative morbidity and mortality were 52% to 30% and 12% to 6%, respectively (p = n.s.). The response to NT was detected in 23 patients (70%). In 11 instances (33%), the primary tumor lesion was histopathologically eradicated. Survival following NT + surgery was significantly prolonged in node-positive patients with a median survival of 12 months to 19 months (p = 0.0193). The average pretreatment time was 113 ± 43 days, and reimbursement for NT to the hospital amounted to Euro 9.834. NT did not increase morbidity and mortality. Expenses for pretreatment, particularly time and costs, are considerable. However, taking into account that the results are derived from a non-randomized study, patients with regionally advanced tumor stages seem to benefit, as seen by their prolonged survival

    Purpose: The aim of this study was to investigate prognostic factors in advanced-stage oral tongue cancer treated with postoperative adjuvant therapy and to identify indications for adjuvant concomitant chemoradiotherapy (CCRT). Methods and Materials: We retrospectively reviewed the records of 201 patients with advanced squamous cell carcinoma of the oral tongue managed between January 1995 and November 2002. All had undergone wide excision and neck dissection plus adjuvant radiotherapy or CCRT. Based on postoperative staging, 123 (61.2%) patients had Stage IV and 78 (38.8%) had Stage III disease. All patients were followed for at least 18 months after completion of radiotherapy or until death. The median follow-up was 40.4 months for surviving patients. The median dose of radiotherapy was 64.8 Gy (range, 58.8-72.8 Gy). Cisplatin-based regimens were used for chemotherapy. Results: The 3-year overall survival (OS) and recurrence-free survival (RFS) rates were 48% and 50.8%, respectively. Stage, multiple nodal metastases, differentiation, and extracapsular spread (ECS) significantly affected disease-specific survival on univariate analysis. On multivariate analysis, multiple nodal metastases, differentiation, ECS, and CCRT were independent prognostic factors. If ECS was present, only CCRT significantly improved survival (3-year RFS with ECS and with CCRT = 48.2% vs. without CCRT = 15%, p = 0.038). In the presence of other poor prognostic factors, results of the two treatment strategies did not significantly differ. Conclusions: Based on this study, ECS appears to be an absolute indication for adjuvant CCRT. CCRT can not be shown to be statistically better than radiotherapy alone in this retrospective series when ECS is not present

    Purpose: Penile squamous cell carcinoma (SCC) is a rare entity, with few published series on outcomes. We evaluated the stage distributions and outcomes for surgery and radiation therapy in a U.S. population database. Methods and Materials: Subjects with SCC of the penis were identified using the National Cancer Institute Surveillance, Epidemiology and End Results (SEER) Program database between 1988 and 2006. Descriptive statistics were performed, and cause-specific survival (CSS) was estimated using Kaplan-Meier analysis. Comparisons of treatment modalities were analyzed using multivariate Cox regression. Subjects were staged using American Joint Committee on Cancer, sixth edition, criteria. Results: There were 2458 subjects identified. The median age was 66.8 years (range, 17-102 years). Grade 2 disease was present in 94.5% of cases. T1, T2, T3, T4, and Tx disease was present in 64.8%, 17.1%, 9.5%, 2.1%, and 6.5% of cases, respectively. N0, N1, N2, N3, and Nx disease was noted in 61.6%, 6.9%, 4.0%, 3.7%, and 23.8% of cases, respectively. M1 disease was noted in 2.5% of subjects. Individuals of white ethnicity accounted for 85.1% of cases. Lymphadenectomy was performed in 16.7% of cases. The CSS for all patients at 5 and 10 years was 80.8% and 78.6%. By multivariable analysis grades 2 and 3 disease, T3 stage, and positive lymph nodes were adverse prognostic factors for CSS. Conclusion: SCC of the penis often presents as early-stage T1, N0, M0, grade 1, or grade 2 disease. The majority of patients identified were treated with surgery, and only a small fraction of patients received radiation therapy alone or as adjuvant therapy.

    Purpose: The optimal management of oral cavity squamous cell carcinoma (OCSCC) typically involves surgical resection followed by adjuvant radiotherapy or chemoradiotherapy (CRT) in the setting of adverse pathologic features. Intensity-modulated radiation therapy (IMRT) is frequently used to treat oral cavity cancers, but published IMRT outcomes specific to this disease site are sparse. We report the Dana-Farber Cancer Institute experience with IMRT-based treatment for OCSCC. Methods and Materials: Retrospective study of all patients treated at Dana-Farber Cancer Institute for OCSCC with adjuvant or definitive IMRT between August 2004 and December 2009. The American Joint Committee on Cancer disease stage criteria distribution of this cohort included 5 patients (12%) with stage I; 10 patients (24%) with stage II (n = 10, 24%),; 14 patients (33%) with stage III (n = 14, 33%),; and 13 patients (31%) with stage IV. The primary endpoint was overall survival (OS); secondary endpoints were locoregional control (LRC) and acute and chronic toxicity. Results: Forty-two patients with OCSCC were included, 30 of whom were initially treated with surgical resection. Twenty-three (77%) of 30 surgical patients treated with adjuvant IMRT also received concurrent chemotherapy, and 9 of 12 (75%) patients treated definitively without surgery were treated with CRT or induction chemotherapy and CRT. With a median follow-up of 2.1 years (interquartile range, 1.1–3.1 years) for all patients, the 2-year actuarial rates of OS and LRC following adjuvant IMRT were 85% and 91%, respectively, and the comparable results for definitive IMRT were 63% and 64% for OS and LRC, respectively. Only 1 patient developed symptomatic osteoradionecrosis, and among patients without evidence of disease, 35% experienced grade 2 to 3 late dysphagia, with only 1 patient who was continuously gastrostomy-dependent. Conclusions: In this single-institution series, postoperative IMRT was associated with promising LRC

    2016-01-01

    The demographics of squamous cell carcinoma of the head and neck (SCCHN) is marked by a growing number of patients aged 65 and over, which is in line with global projections for other cancer types. In developed countries, more than half of new SCCHN cases are diagnosed in older people, and in 15 years from now, the proportion is expected to rise by more than 10%. Still, a high-level evidence-based consensus to guide the clinical decision process is strikingly lacking. The available data from retrospective studies and subset analyses of prospective trials suffer from a considerable underrepresentation of senior participants. The situation is even more challenging in the recurrent and/or metastatic setting, where usually only palliative measures are employed. Nevertheless, it is becoming clear that, if treated irrespective of chronological age, fit elderly patients in a good general condition and with a low burden of comorbidities may derive a similar survival advantage as their younger counterparts. Despite that, undertreatment represents a widespread phenomenon and, together with competing non-cancer mortality, is suggested to be an important cause of the worse treatment outcomes observed in this population. Due to physiological changes in drug metabolism occurring with advancing age, the major concerns relate to chemotherapy administration. In locally advanced SCCHN, concurrent chemoradiotherapy in patients over 70 years remains a point of controversy owing to its possibly higher toxicity and questionable benefit. However, accumulating evidence suggests that it should, indeed, be considered in selected cases when biological age is taken into account. Results from a randomized trial conducted in lung cancer showed that treatment selection based on a comprehensive geriatric assessment (CGA) significantly reduced toxicity. However, a CGA is time-consuming and not necessary for all patients. To overcome this hurdle, geriatric screening tools have been introduced

    In this retrospective study the results of primary and salvage treatment of oropharyngeal carcinoma were evaluated. A total of 289 consecutive patients (103 females and 186 males) were included in the study. Most tumours originated in the tonsil area (58%) and comprised stages I 8%, II 19%, III 46% and IV 28%. The primary treatment was delivered with curative intent in 276 cases (96%). Of these, 266 received primary radiotherapy. The median radiation dose was 62 Gy, given as laterally opposed fields to the primary tumour and bilateral neck. Eight patients were treated with primary surgery and two with chemotherapy as part of a curatively intended treatment programme including radiotherapy. Six patients received palliative treatment, and seven were not treated at all. Out of 276 tumours treated with curative intent, 173 reappeared; 72% recurred in T position, 38% in N position, and 12% at distant metastatic sites, some in combination. Salvage surgery was possible in 52 patients, and 24 treatments were successful. Salvage radiotherapy or cryotherapy was used in 22 patients and 4 were controlled. For the entire group, the 5-year locoregional tumour control, disease-specific survival and overall survival rates were 38%, 44% and 31%, respectively. For patients treated with curative intent, clinical T- and N-stage, stage, tumour size, gender, age, and pretreatment haemoglobin were significant prognostic parameters in a univariate analysis. The Cox multivariate analysis showed that T-stage, N-stage and gender were independent prognostic factors. It is concluded that T-stage, N-stage and gender are significant independent prognostic factors. The primary control of the carcinoma in the T-position is crucial for overall success, but salvage surgery is found to have a favourable success rate in patients suitable for relapse treatment.

    There is an urgent need for novel effective treatment for hepatocellular carcinoma (HCC). Oncolytic viruses (OVs) not only directly lyse malignant cells, but also induce potent antitumour immune responses. The potency and precise mechanisms of antitumour immune activation by attenuated measles virus remain unclear. In this study, we investigated the potency of the measles virus vaccine strain Edmonston (MV-Edm) in improving adoptive CD8 + NKG2D + cells for HCC treatment. We show that MV-Edm-infected HCC enhanced the antitumour activity of CD8 + NKG2D + cells, mediated by at least three distinct mechanisms. First, MV-Edm infection compelled HCC cells to express the specific NKG2D ligands MICA/B, which may contribute to the activation of CD8 + NKG2D + cells. Second, MV-Edm-infected HCC cells stimulated CD8 + NKG2D + cells to express high level of FasL resulting in enhanced induction of apoptosis. Third, intratumoural administration of MV-Edm enhanced infiltration of intravenously injected CD8 + NKG2D + cells. Moreover, we found that MV-Edm and adoptive CD8 + NKG2D + cells, either administered alone or combined, upregulated the immune suppressive enzyme indoleamine 2,3-dioxygenase 1 (IDO1) in HCC. Elimination of IDO1 by fludarabine enhanced antitumour responses. Taken together, our data provide a novel and clinically relevant strategy for treatment of HCC.

    The purpose of this study was to evaluate the outcome of primary treatment and treatment of recurrences in patients with nasopharyngeal carcinoma. The material included 149 consecutive patients seen at the Aarhus University Hospital from 1963 to 1991 (49 females and 100 males). The stage distribution was: Stage I -9%, II-3%, III-28%, and IV-60%. Primary treatment was delivered with curative intent in 145 patients (97%). Persistent or recurrent disease after primary radical treatment was observed in 82 of the patients; 54% at the T-level, 40% at the N-level, and 33% at the M-level. A curative salvage attempt was carried out in 14 patients only, all with nodal recurrence: surgery in 8 patients (4 controlled) and radiotherapy in 6 patients (2 controlled). The 5-year local tumour control, locoregional tumour control, disease-specific survival rate and the overall survival rate for the patients treated with curative intent were 66%, 53%, 50% and 43%, respectively. Most of the patients (88%) had poorly differentiated tumours and these patients had the best prognosis. A major complication in three patients was radiation-induced myelopathy due to high-dose radiation delivered to the brain stem. Significant positive prognostic factors for treatment outcome in univariate analyses were early T-classification, small clinical stage, poor differentiation and low age. The Cox multivariate analysis showed that early T-categories, low N-categories and poor differentiation were independent, positive prognostic factors. Nasopharyngeal carcinoma is curable with primary radiotherapy; patients with poorly differentiated tumours have the best prognosis. Only a few patients were salvaged after recurrence. The factor most essential for success is primary control of the disease at the T- and N-levels

    Intravesical instillation of Bacillus Calmette-Guérin (BCG) remains a first-line treatment for superficial transitional cell carcinoma of the bladder. Although its use is relatively safe, severe complications such as granulomatous hepatitis, osteomyelitis, pneumonitis, and sepsis occur in few patients. Complications of intravesical instillation of BCG can be local or systemic, with early or late presentation. Here, we report an 88-year-old man who developed fever, rigors, and episodes of syncope following fourth intravesical BCG instillation for the treatment of superficial transitional cell carcinoma of the bladder. Pancytopenia, disseminated intravascular coagulation, ground glass appearance on computerized tomography of the chest scan in addition to multiple bone marrow granulomas, suggested the diagnosis of disseminated BCG infection. All these features recovered on antituberculosis treatment. Our case study highlights the importance of early recognition and prompt treatment of patients with disseminated BCG infection following intravesical instillation. Although isolation of mycobacterium is desirable to make the diagnosis, it is not unusual to have negative smears and cultures and this should not be used to dismiss the possibility of BCG infection.

    One of the major challenges of modern genetics is to apply recent advances in mutation research to improve the accuracy of the estimates of the genetic risk for humans. Because of the important implications for radiation protection, biological effects of low-dose radiation have been a focus of research in recent years. Previously we have found that human cervical carcinoma HeLa cells irradiated repeatedly with low doses of gamma rays (HeLa1500 cells) became resistant to cisplatin. In this study we examine whether this effect was caused by inhibition of apoptosis. In HeLa and HeLa1500 cells we determined the induction of apoptosis following the treatment with cisplatin (i) by counting apoptotic cells with characteristic morphological changes, (ii) by analysing the expression of apoptotic genes involved in cytochrome c/Apaf-1/caspase-9 and in Fas/FasL pathways by Western blot method, and (iii) by estimating the activities of caspases by commercial caspase detection kits. Our results show that low doses of gamma rays induced alterations in human cervical carcinoma cells that were reflected in inhibition of p53-independent cisplatin-induced apoptosis due to reduced activity of caspase 3.

    To provide an overview of the current knowledge and treatment options for renal cell carcinoma (RCC). Published articles, published abstracts, online databases, and package inserts. Researchers have an increased understanding of the genetic and prognostic risk factors associated with RCC. Most patients with this rare type of cancer have or will develop metastasis. Nephrectomy treats localized disease and cytokine therapy was the previous standard for metastatic disease, but newly approved targeted agents, such as sorafenib, temsirolimus, and sunitinib, as well as investigational agents such as bevacizumab, are improving patient outcomes. Understanding the biologic basis of RCC has led to therapies that are transforming the goals for treatment outcomes in patients with metastatic disease and increasing time to progression with manageable side effects. Counseling patients and managing treatment-related side effects of therapy are critical interventions for healthcare professionals caring for patients with RCC. Evolving treatments for metastatic disease are providing better options for patients and changing disease management.

    Incidence of isolated distant metastasis (IDM) was relatively low in patients who achieved locoregional control after primary definitive surgery. However, the prognosis of patients with IDM was dismal. The aim of this study was to evaluate the clinical outcome of patients with IDM and identify independent predictive factors of IDM after primary definitive surgery for head and neck squamous cell carcinoma (HNSCC). A retrospective data review was conducted for 795 patients who underwent primary definitive surgery without any systemic treatment for squamous cell carcinoma (SCC) of the oral cavity, oropharynx, larynx, and hypopharynx. Distant metastasis-free survival was calculated and independent predictive factors for IDM were determined by Cox proportional-hazards model. For the entire study cohort, IDM developed in 75 patients (9.4%). Among 631 patients who achieved locoregional control, IDM occurred in 44 patients (7%). The median time to IDM after primary surgery was 13months, ranging from 2 to 70months. The overall salvage rate was 9% (4 of 44) after salvage treatment for IDM. In the Cox proportional-hazards model, clinical N status, and histological grade were independent predictive factors of IDM. Patients who had clinically palpable neck disease and a histologically poor grade were more likely to develop IDM after primary definitive surgery. Patients with these factors should be considered candidates for proper adjuvant systemic treatment and evaluated more thoroughly for early detection of IDM during follow-up.

A case of mRCC was reported which recurred after surgery and roferon treatment. The patient was treated with apatinib at a dose of 500 mg orally, twice daily, 28 days/cycle. The metastatic lesions improved based on computed tomography after apatinib administration in the fourth and eighth month. The progression-free survival of the patient had increased almost to 8 months. The patient showed a good tolerance with only an adverse effect of mild-to-moderate hand-foot syndrome which was managed well. Apatinib is an option for mRCC after previous treatment. However, more and larger trials are still needed. Keywords: metastatic renal cell carcinoma, apatinib, sunitinib, sorafenib, vascular endothelial growth factor receptor

    Tumors originating from transitional epithelium of the renal pelvis and ureter are infrequent. Their course is asymptomatic at early stages of the disease, and diagnosis and institution of appropriate treatment delayed. The aim of the study is to assess the results of treatment in patients with upper urinary tract transitional cell carcinomas (UUT-TCC). Fifteen patients treated in 2005-2010 for UUT-TCC were qualified for the retrospective study. Clinical symptoms, diagnostic methods, tumor location, clinical stage and histopathological characteristics of the tumors were assessed. Then, the instituted treatment and its results were analyzed. The average follow-up period was 51 month (range 6-65), UUT-TCC accounted for 6.7% of renal tumors treated. Concurrent treated vesical tumors were observed in 4 (26.7%) patients. Primary UUT-TCC was diagnosed in 10 (66.7%) patients. Radical surgery was performed in 10 (66.7%) patients, whereas 5 (33.3%) underwent sparing operations. Macroscopic hematuria was the predominant clinical symptom. In most cases T2-T3 clinical stage (60.0%) and high-grade (66.7%) were observed. Development of an upper urinary tract tumor after treatment of a vesical tumor was noted in 4 (26.7%) patients. During the follow-up period, urinary bladder carcinomas were diagnosed in 5 (33.3%) patients with primary upper urinary tract tumors. Nephroureterectomy remains the standard treatment for UUT-TCC. Organ-sparing surgery is possible in selected patients with low clinical stage and low grade tumors. Patients treated for urinary bladder carcinomas require regular monitoring of the upper urinary tract.

    We performed a retrospective analysis of the association between tumor HPV status and the demographic and clinicopathological parameters of 83 patients with oropharyngeal squamous cell carcinoma at Hokkaido University Hospital, Japan, between 1998 and 2010. The parameters included age, gender, tumor subsite, Tumor-Node-Metastasis (TNM) stage, and overall survival. HPV status was established by multiplex polymerase chain reaction analysis. Of the 83 oropharyngeal cancers, 22 were positive for HPV-16, two for HPV-18, and one for HPV-35 and HPV-58. Kaplan-Meier survival analysis showed improved overall survival rates in patients with HPV-positive tumors (p=0.0024) compared with HPV-negative tumors. Of the 51 patients who received chemoradiotherapy, HPV-positive patients experienced better overall survival than HPV-negative patients (p=0.0024). HPV status is a significantly favorable prognostic factor in oropharyngeal cancer in Japan. (author)

    Full Text Available Context (Background: Imiquimod (IMQ 5% cream is an immunomodulatory and antitumorigenic agent, which was used as a topical treatment regimen, who had periocular basal cell carcinoma (BCC. Aim: This study aims to present three cases with large BCC at the medial canthal area treated with IMQ 5% cream. Materials and Methods: IMQ 5% cream was used in three patients with ages 45, 49, and 73 who preferred medical treatment over surgery. Following incisional biopsy IMQ cream was used once a day, 5 times a week and the patients were followed up weekly during 12 week treatment period and monthly after the clearance of the lesion. Results: Erythema and erosion on the surface of the lesion, injection of conjunctiva, burning and itching sensation, epiphora and punctate keratitis were seen in all patients during the treatment period. The ophthalmic side effects could be managed by topical lubricating eye drops and the inflammatory reactions resolved within 1 month after cessation of therapy. The patients were followed up for at least 3 years without tumor recurrence and the biopsies taken from the suspected area were found to be tumor free. Conclusion: Surgical excision of carcinoma of the eyelid at medial canthal area can be difficult without causing damage to the lacrimal system and reconstruction of the defect may need grafts or flaps. IMQ may provide an alternative therapy to surgery in certain cases.

    Our aim was to present the results from a retrospective study of 7 cases of squamous cell carcinoma arising from chronic osteomyelitis. We treated seven cases of chronic osteomyelitis related squamous cell carcinoma between 1993 and 2005. The patients had an average age of 54.5 (range: 38-71) years, with a male predominance (6 men, 1 woman). We analyzed the time up to cancerization, the localization and histopathological type of the carcinoma, and the type and result of the treatment. The mean time between the occurrence of the skin lesions and the diagnosis of malignant degeneration was 24.5 (range: 9 to 40) years. The carcinoma resulted from tibia osteomyelitis in 4 cases, femur osteomyelitis in 2 cases and humerus osteomyelitis in one. The pathological examination showed five cases of a well differentiated squamous cell carcinoma with bone invasion, and two cases of invasive squamous cell carcinoma. The treatment consisted of amputation in all but one patient, who refused the amputation. The six amputee patients did not show local recurrence or metastatic dissemination over a period of five years. Amputation appears to be an effective treatment method in squamous carcinoma secondary to chronic osteomyelitis.

    Full Text Available Basal cell carcinoma (BCC is the most common non-melanoma skin cancer. Exposure to ultraviolet light is an important risk factor for BCC development and the disorder therefore develops commonly on body areas that are more exposed to sunlight, such as the face and neck. It is uncommon in the closed area of the body and quite rare in the perianal and genital regions. Herein, we report a 34-year-old patient with perianal BCC who had no additional risk factors.

    Full Text Available Cancer has become a first order health problem worldwide, despite the great diagnostic and therapeutic programs achieved during the last years. This is a clinical case of an 81- year-old patient with personal and social history of promiscuous and unprotected sexual behavior that shows a vegetative lesion in his gland and numerous inguinal adenopathies. Biopsy confirms the diagnosis of squamous cell carcinoma infiltrating the penis, which is a relatively rare pathology which is generally diagnosed belatedly. Partial amputation of the penis was considered to be performed, but there was no consent on behalf of his family. The patient’s general condition was getting worse until he died.

    Full Text Available Oncolytic viruses (OVs are emerging as powerful anti-cancer agents and are currently being tested for their safety and efficacy in patients. Reovirus (Reolysin, a naturally occurring non-pathogenic, double-stranded RNA virus, has natural oncolytic activity and is being tested in phase I–III clinical trials in a variety of tumor types. With its recent US Food and Drug Administration (FDA orphan drug designation for several tumor types, Reolysin is a potential therapeutic agent for various cancers, including head and neck squamous cell carcinomas (HNSCCs, which have a 5-year survival of ∼55%. Histone deacetylase inhibitors (HDACis comprise a structurally diverse class of compounds with targeted anti-cancer effects. The first FDA-approved HDACi, vorinostat (suberoylanilide hydroxamic acid [SAHA], is currently being tested in patients with head and neck cancer. Recent findings indicate that HDAC inhibition in myeloma cells results in the upregulation of the Reolysin entry receptor, junctional adhesion molecule 1 (JAM-1, facilitating reovirus infection and tumor cell killing both in vitro and in vivo. In this study, we tested the anti-tumor efficacy of HDAC inhibitors AR-42 or SAHA in conjunction with Reolysin in HNSCCs. While HDAC inhibition increased JAM-1 and reovirus entry, the impact of this combination therapy was tested on the development of anti-tumor immune responses.

    Basaloid squamous cell carcinoma (BSC) is a rare variant of squamous cell carcinoma (SqCC) of the esophagus. Even though pathologically thought to be more aggressive than SqCC, there is discrepancy in the literature regarding the outcomes of BSC compared with those of SqCC. We conducted a retrospective cohort study using the Surveillance Epidemiology and End Results (SEER) database. All patients with a histologic diagnosis of BSC and SqCC between 2004 and 2013 were included. We compared treatment and survival characteristics of patients with BSC and SqCC. There were 16,158 patients included in this study; 173 patients (1.1%) had BSC. There were no significant differences between the 2 groups based on age, sex, marital status, insurance, or geographic region of diagnosis, but patients with BSC were more likely to be Caucasian (73.4% vs 64.7%; p = 0.017). Among staged patients, baseline tumor stage was similar in both groups. However, BSC tumors were more likely to be of high pathologic grade (56.8% vs 38.2%; p BSC were more likely to undergo resection (32.4% vs 17.0%; p BSC of the esophagus seems to have similar clinical features and survival outcomes when compared with SqCC. Patients with BSC and SqCC should undergo stage-specific treatment to achieve optimal outcomes. Copyright © 2017 American College of Surgeons. Published by Elsevier Inc. All rights reserved.

    Carcinomas of the kidney generally have a poor prognosis and respond minimally to classical radiotherapy or chemotherapy. Immunotherapy constitutes an interesting alternative to these established forms of treatment, and indeed, cytokine-based therapies have been used for many years, leading to favorable clinical responses in a small subset of patients. During the past few years, immunotherapeutical trials targeting renal cell tumor-associated antigens have also been reported, with diverse passive or active approaches using antibodies or aimed at activating tumor-directed T lymphocytes. The following review presents the results and the progress made in the field, including classical cytokine treatments, non-myeloablative stem cell transplantation and antigen specific-based trials, with special focus on T-cell studies. In consideration of the few specific molecular targets described so far for this tumor entity, current strategies which can lead to the identification of new relevant antigens will be discussed. Hopefully these will very soon contribute to an improvement in renal cell carcinoma specific immunotherapy and its evaluation.

    Full Text Available Due to the rarity of Merkel cell carcinoma (MCC, prospective clinical trials have not been practical. This study aimed to identify biomarkers with prognostic significance. While sixty-two patients were identified who were treated for MCC at our institution, only seventeen patients had adequate formalin-fixed paraffin-embedded archival tissue and followup to be included in the study. Patients were stratified into good, moderate, or poor prognosis. Laser capture microdissection was used to isolate tumor cells for subsequent RNA isolation and gene expression analysis with Affymetrix GeneChip Human Exon 1.0 ST arrays. Among the 191 genes demonstrating significant differential expression between prognostic groups, keratin 20 and neurofilament protein have previously been identified in studies of MCC and were significantly upregulated in tumors from patients with a poor prognosis. Immunohistochemistry further established that keratin 20 was overexpressed in the poor prognosis tumors. In addition, novel genes of interest such as phospholipase A2 group X, kinesin family member 3A, tumor protein D52, mucin 1, and KIT were upregulated in specimens from patients with poor prognosis. Our pilot study identified several gene expression differences which could be used in the future as prognostic biomarkers in MCC patients.

    The authors report 1,166 tumors of the eyelids that were treated by single or fractionated exposures to doses of 20-60 Gy. The five year tumor control rate was 95% for basal cell and 93.3% for squamous cell carcinoma. Irradiation was equally successful in primary cases and in those recurrent following surgery. The cosmetic and functional results were generally excellent and readily accepted by most patients. The overall complication rate was 9.6% with fewer than one-half rated as serious; these problems mainly occurred with large tumors that had destroyed normal tissues. In only 14 (1.2%) patients was death related to the tumor. Approximately one-half of the patients received a dose of 35 Gy in five daily fractions, one-quarter, 20 to 22.5 Gy in a single exposure and the others with larger tumors 42.5-60 Gy in 10 to 30 exposures in two to six weeks.

    Hepatocellular carcinoma (HCC) is frequently diagnosed at advanced stages and has a high mortality rate. With improved survival of patients with cirrhotic liver disease and increased prevalence of chronic hepatitis C viral infections, a rise in the number of HCC cases is being reported worldwide. Early diagnosis and treatment can significantly improve the prognosis of patients with HCC. Although surgical resection is an important potentially curative therapy for liver tumors, in appropriately selected patients, liver transplantation has been shown to achieve excellent survival rates for a solid tumor. Locally ablative and locoregional therapies in the form of percutaneous ethanol injection, radiofrequency ablation, transcatheter arterial chemoembolization and transcatheter arterial radioembolization (TheraSphere) are viable options in patients with unresectable HCC. Unfortunately, the role of systemic therapy has been very limited in the treatment of these patients. Novel treatment options based on an improved understanding of the molecular pathogenesis of HCC are being explored. These targeted molecular therapies are aimed at growth factors and their receptors, intracellular signal transduction and cell cycle control. A substantial improvement in outcomes of intermediate and advanced stage HCC is expected with the advent of these targeted therapies, used in combination with surgical or locoregional therapies. Recent positive results from a large Phase III study of the receptor tyrosine kinase inhibitor, sorafenib, hold great promise in the treatment of HCC.

  3. Transfer of intestine-derived diamines into tumour cells during treatment of Ehrlich-ascites--carcinoma-bearing mice with polyamine anti-metabolites.

    1984-01-01

    Treatment of Ehrlich-ascites-carcinoma-bearing mice with methylglyoxal bis(guanylhydrazone) alone or in combination with 2-difluoromethylornithine greatly enhanced the transfer of intragastrically administered radioactive putrescine and cadaverine into the carcinoma cells. Difluoromethylornithine alone did not have any effect on the accumulation of intestine-derived diamines in the tumour cells. The frequently reported restoration of difluoromethylornithine-induced polyamine depletion on administration of methylglyoxal bis(guanylhydrazone) is in all likelihood attributable to a profound inhibition of intestinal diamine oxidase (EC 1.4.3.6), resulting in an enhanced entry of intestinal (bacterial) diamines into general circulation and finally into tumour cells.

    Oncological research and cancer treatment are more common in human medicine than in veterinary medicine. Nevertheless the latest decennium chemotherapy, radiotherapy and surgery also figure largely in the cancer treatment of pets. For this matter, the present study tried to explore the applicability of Photodynamic Therapy (PDT) as a proper and advantageous alternative for those treatments. PDT using topical 5-aminolaevulinic acid (5-ALA) cream was applied on superficial squamous cell carcinomas (SCC) at the nasal planum of two cats. Five hours after the cream was applied, the photosensitizing agent was removed and the sensitized area was irradiated with a red Light Emitting Diode (LED) contrivance with a wavelength of 660 nm. LED irradiation was administrated during 20 minutes, at a power output of 80 mW, with an energy density outcome of 38 J/cm2. The day after ths irradiation, the tumor area became erythematous and somewhat oedematous. After two days a scab occurred. Long-term post treatment observation showed complete removal of the malign cells related with regain of normal skin structure after three weeks. Follow-up period of one year for the first case and of two months for the second case revealed no recurrence. These promising results indicate that PDT is a possible alternative method to treat superficial skin tumors. Especially when taking into account that chemotherapy and radiotherapy are time-consuming treatments and that surgery (complete removal of the nasal planum) is not an esthetical solution.

    2014-01-01

    Basal cell carcinoma (BCC) is the most common skin cancer in humans, which typically appears over the sun-exposed skin as a slow-growing, locally invasive lesion that rarely metastasizes. Although the exact etiology of BCC is unknown, there exists a well-established relationship between BCC and the pilo-sebaceous unit, and it is currently thought to originate from pluri-potential cells in the basal layer of the epidermis or the follicle. The patched/hedgehog intracellular signaling pathway plays a central role in both sporadic BCCs and nevoid BCC syndrome (Gorlin syndrome). This pathway is vital for the regulation of cell growth, and differentiation and loss of inhibition of this pathway is associated with development of BCC. The sonic hedgehog protein is the most relevant to BCC; nevertheless, the Patched (PTCH) protein is the ligand-binding component of the hedgehog receptor complex in the cell membrane. The other protein member of the receptor complex, smoothened (SMO), is responsible for transducing hedgehog signaling to downstream genes, leading to abnormal cell proliferation. The importance of this pathway is highlighted by the successful use in advanced forms of BCC of vismodegib, a Food and Drug Administration-approved drug, that selectively inhibits SMO. The UV-specific nucleotide changes in the tumor suppressor genes, TP53 and PTCH, have also been implicated in the development of BCC.

    1998-01-01

    Purpose: At least in some European Countries, there is still considerable controversy regarding the choice between surgery and radiotherapy for the treatment of patients with early laryngeal-glottic carcinoma. Methods and Materials: Two hundred and forty-six patients with laryngeal-glottic neoplasms, Stage I-II, were treated with radical radiotherapy. Before radiotherapy the patients were evaluated to determine the surgical procedure of choice. Either 66-68.4 Gy (33-38 fractions) or 63-65 Gy (28-29 fractions) of radiation therapy (RT) were administered. The overall disease free survival was determined for each subgroup of patients. Univariate and multivariate analyses were performed to determine significant prognostic variables. Results: Five- and 10-year overall survival rates were 83 and 72%, respectively. At a median follow-up of 6 years 204 patients are alive and disease free. No patient developed distant metastases. One patient died of a large local recurrence, 38 patients died of causes unrelated to their tumor, and 3 patients were lost to follow-up. The multivariate analysis confirmed that performance status (PS), macroscopic presentation of the lesion, and persistence of dysphonia after radiotherapy are significant prognostic factors. Conclusions: According to the multivariate analysis, the patients with PS >80 and with exophytic lesions are eligible for radical RT. The surgical procedure proposed for each patient was not found to be an independent prognostic factor

The clinical observation presents a case of synchronous bilateral renal cell carcinoma and simultaneous metastatic involvement of both adrenal glands. A 55‑year-old male patient was adm tted with the signs of hematuria and anemia to the Unit of Urology, Clinic of General Surgery, Siberian State Medical University. He was found to have synchronous bilateral renal cell carcinoma and simultaneous bilateral adrenal involvement. Sequential surgical treatment – radical nephrectomy (with adrenal gland removal on the right side and, after 3 months, adrenalectomy and kidney resection on the left side were performed. All the organs removed displayed tumors that proved to be renal cell carcinomas (a clear cell variant. There were lymph node metastases in the right-sided renal portal. Postoperatively, the investigators performed hormone replacement therapy for adrenal insufficiency, an immunotherapy cycle, three cycles of targeted therapy withsorafenib and sunitinib (at an interval of 0.5–2 years, and insulin therapy for new-onset diabetes mellitus. The duration of a follow-up was 6.2 years. When describing the case, the patient was alive and showed a generalized tumorous process with extensive tumor involvement of the solitary kidney. Sunitinib therapy was used.

    1996-01-01

    Purpose: To define patient, tumor, and treatment factors that influence the outcome of patients with FIGO Stage IIIB squamous cell carcinoma of the intact uterine cervix. Materials and Methods: The hospital and radiotherapy records of 1007 consecutive patients treated between 1960 and 1989 for FIGO Stage IIIB squamous cell carcinoma of the intact uterine cervix were reviewed retrospectively. All patients were treated with radiation therapy (RT) either with curative intent (903 patients) or to palliate symptoms (104 patients). Patients who were selected for palliative treatment usually had a combination of adverse characteristics including massive tumor with bilateral pelvic wall fixation, hydronephrosis, bulky adenopathy, pathologic evidence of extrapelvic disease, and poor performance status. 64 (7%) of 903 patients failed to complete planned curative RT either because of progressive disease, complications, or poor compliance. Of 903 patients treated with curative intent, 319 (35%) were treated with external beam radiotherapy (EBRT) alone and 586 (65%) were treated with a combination of EBRT and intracavitary irradiation (ICRT). EBRT was usually delivered using 18-25 MV photons and ICRT was administered with Fletcher-Suit-Delclos applicators. Treatment philosophies evolved during the study period with greater emphasis placed on EBRT between 1966 and 1979 (52% treated with EBRT alone) compared with the other study years (15% treated with EBRT alone). 206 patients received investigational treatments including neutrons (69 pts), hyperbaric oxygen (66 pts), concurrent chemotherapy (29 pts), or neoadjuvant chemotherapy (42 pts). 875 patients have been followed until death. Median follow up for surviving patients is 171 months with only 9 surviving patients followed for 10%, or hgb < 10 gm% before treatment or at any time during radiotherapy. DSS was significantly better for patients whose treatment included ICRT (43% vs 21%; P< 0.0001). Also, patients who received

    The number of cases of non-melanoma skin cancer (NMSC), which include squamous cell carcinoma (SCC) and basal cell carcinoma (BCC), continues to rise as the aging population grows. Mohs micrographic surgery has become the treatment of choice in many cases but is not always necessary or feasible. Ablation with a high-powered CO2 laser offers the advantage of highly precise, hemostatic tissue removal. However, confirmation of complete cancer removal following ablation is difficult. In this study we tested for the first time the feasibility of using Raman spectroscopy as an in situ diagnostic method to differentiate NMSC from normal tissue following partial ablation with a high-powered CO2 laser. Twenty-five tissue samples were obtained from eleven patients undergoing Mohs micrographic surgery to remove NMSC tumors. Laser treatment was performed with a SmartXide DOT Fractional CO2 Laser (DEKA Laser Technologies, Inc.) emitting a wavelength of 10.6 μm. Treatment levels ranged from 20 mJ to 1200 mJ total energy delivered per laser treatment spot (350 μm spot size). Raman spectra were collected from both untreated and CO2 laser-treated samples using a 785 nm diode laser. Principal Component Analysis (PCA) and Binary Logistic Regression (LR) were used to classify spectra as originating from either normal or NMSC tissue, and from treated or untreated tissue. Partial laser ablation did not adversely affect the ability of Raman spectroscopy to differentiate normal from cancerous residual tissue, with the spectral classification model correctly identifying SCC tissue with 95% sensitivity and 100% specificity following partial laser ablation, compared with 92% sensitivity and 60% selectivity for untreated NMSC tissue. The main biochemical difference identified between normal and NMSC tissue was high levels of collagen in the normal tissue, which was lacking in the NMSC tissue. The feasibility of a combined high-powered CO2 laser ablation, Raman diagnostic procedure for the

    Vascular endothelial growth factor (VEGF) inhibitors, including targeted therapy with tyrosine kinase inhibitors (TKIs) and the angiogenesis inhibitor bevacizumab, and mammalian target of rapamycin (mTOR) inhibitors are now the standard of care for metastatic renal cell carcinoma (mRCC). However, real-world treatment patterns are not well characterized. To describe treatment patterns during the first, second, and third lines of targeted therapies for mRCC among community oncologists in the US. Participating physicians recruited from a nationwide panel each identified up to 15 adult mRCC patients who initiated a second therapy after January 2010. Information extracted from medical records included types of targeted therapies, reasons for treatment choices, patterns of treatment discontinuation, and dose adjustments. Thirty-six physicians contributed charts from 433 mRCC patients. Seventy-seven percent of patients received a VEGF inhibitor as first targeted therapy; 23% received an mTOR inhibitor. Among first-line VEGF users, second-line treatments were 66% mTOR and 34% VEGF inhibitors. Among first-line mTOR users, second-line treatments were 94% VEGF and 6% mTOR inhibitors. Sunitinib followed by everolimus was the most commonly used treatment sequence. Estimated median duration for second targeted therapy was 8.6 months, and median overall survival (OS) and progression-free survival (PFS) were 27.4 and 10.8 months, respectively. Efficacy, treatment guidelines and mechanism of action were the most important considerations for treatment choice. LIMITATIONS include no adjustment for baseline characteristics, possible difference between physician-defined progression and central review in the clinical trial setting, and limited data availability for axitinib during the study period. In this large retrospective chart review among community oncologists, VEGF-mTOR-VEGF was the most common treatment sequence for mRCC. The most common drugs were sunitinib in the first line

    Increasing exposure to UV radiation is considered the most important etiologic factor of nonmelanoma skin cancers. Consequently, exposed areas such as the scalp and face, are the primary areas for developing non-melanoma skin cancers. Once a patient has presented with one tumor, additional lesions are common. The diagnosis is based on typical clinical picture and biopsy or excision for histopathological analysis. Various non-surgical treatment options have been established. Superficial basal cell carcinoma, superficial carcinoma in situ and all actinic keratoses are preferentially treated non-surgically. Most other basal cell and squamous cell carcinomas should be surgically removed.

    Objective: To evaluate treatment results and prognostic factors of 47 patients with primary urethral transitional cell carcinoma treated with post-operative adjuvant radiotherapy. Methods: From October 1998 to October 2008, 47 patients with primary urethral transitional cell carcinoma received postoperative adjuvant radiotherapy. Thirty-one patients had stage T 3 /T 4 disease, 7 had lymph node metastasis. Thirty-nine patients had G3 tumor, 13 had stump-positive. The median radiotherapy dose was 60 Gy (36-64 Gy). 81% patients (38/47) were treated with regional irradiation. Results: The median follow-up time was 21 months (6 -88 months). The follow-up rate was 92%. The median overall survival time was 35 months (5 -88 months). The 2-and 5-year overall survival rates were 57% and 49%, respectively. In univariate analysis, the median overall survival time was better in patients with stage T 1 or T 2 compared with stage T 3 or T 4 tumor (42 months vs. 19 months, χ 2 =7.28, P=0.007), with age of ≤65 years compared with >65 years (28 mouths vs 18 months,χ 2 =8.23, P =0.004). There was no significant difference in the long term survival in patients with non-radical surgery compared with radical mastectomy (21 months vs. 20 months, χ 2 = 0.90, P = 0.344). In multivariate analysis, the stage T 3 or T 4 (χ 2 = 7.89, P =0.005), >65 years old (χ 2 = 4.85, P = 0.028), renal pelvis involvement (χ 2 = 5.65, P = 0.018), and tumor located in the mid or inferior segment (χ 2 =6.08,P =0.014) were factors associated with poorer prognosis. Conclusions: Postoperative adjuvant radiotherapy can improve the efficacy of patients with locally advanced urethral transitional cell carcinoma. Advanced T stage and > 65 years age are associated with poorer prognosis. (authors)

    To describe the clinical characteristics, treatment patterns and outcomes in advanced small cell bladder cancer (aSCBC) patients and compare to those with urothelial carcinoma (UC). Individuals in the National Cancer Data Base with a diagnosis of either nodal (TxN+M0) or distant metastatic (TxNxM1) disease were identified from 1998 to 2010. We assessed the relationships between stage, treatment modalities and survival in the aSCBC cohort and compared these to UC patients. In the 960 patient aSCBC cohort (62% M1), 50% received palliative therapy alone, 68% in M1 versus 21% in M0 groups (P < 0.0001). Single modality local therapy (15%) and surgical (21%) or radiation-based (14%) multimodal therapy (MMT) were used in the other 50%. Cystectomy-based MMT was utilized in 45% of N+M0 versus 6.4% of NxM1 patients (P < 0.0001). Median overall survival (OS) for aSCBC patients was 8.6 months; 13.0 months in N+M0 versus 5.3 months in NxM1 patients (P < 0.0001). Survival was similar between TxN1M0 and TxN2-3M0 patients (14.8 months vs. 12.1 months, P = 0.15). Urothelial carcinoma patients (n = 27,796, 45% M1) lived longer compared to aSCBC patients in the N+M0 group (17.3 months vs. 13.0 months, P = 0.0007). There were not clinically significant differences in OS between UC and aSCBC patients in the M1 group. Advanced SCBC is a rare disease with a poor survival and palliative therapy is common, especially in M1 patients. In comparison to UC, the outcomes for aSCBC patients are worse in those with lymph node only involvement but similar in those with distant disease

    Full Text Available Abstract Background Despite the recently reported drop in the overall death rate from cancer, the estimated survival rate and number of deaths from oral cancer remain virtually unchanged. Early detection efforts, in combination with strategies for prevention and risk-reduction, have the potential to dramatically improve clinical outcomes. The identification of non-toxic, effective treatments, including complementary and alternative therapies, is critical if the survival rate is to be improved. Epidemiologic studies have suggested a protective effect from certain plant-derived foods and extracts; however, it has been difficult to isolate and identify the compounds most responsible for these observations. The primary purpose of this study was to investigate the response of human oral squamous cell carcinoma (OSCC to proanthocyanidin (PAC, a plant-derived compound that may inhibit the progression of several other cancers. Methods Using a series of in vitro assays, we sought to quantify the effects of PAC on OSCC, cervical carcinoma, and non-cancerous cell lines, specifically the effects of PAC on cell proliferation. Recent data suggest that infection with the human papillomavirus (HPV may also modulate the proliferative potential of OSCC; therefore, we also measured the effects of PAC administration on HPV-transfected OSCC proliferation. Results Our results demonstrated that PAC administration was sufficient to significantly suppress cellular proliferation of OSCC in a dose-dependent manner. In addition, the increased proliferation of OSCC after transfection with HPV 16 was reduced by the administration of PAC, as was the proliferation of the cervical cancer and non-cancerous cell lines tested. Our results also provide preliminary evidence that PAC administration may induce apoptosis in cervical and oral cancer cell lines, while acting merely to suppress proliferation of the normal cell line control. Conclusion These results signify that PAC may be

    Full Text Available Head and neck squamous cell carcinoma (HNSCC accounts for a large oncologic burden in the developing countries. In patients with locally advanced head and neck cancer multimodality treatment is warranted. Radiation therapy with concurrent chemotherapy has long been considered the standard for patients with disease involving the oropharynx, larynx and hypopharynx. However, addition of chemotherapy to radiotherapy increases treatment related toxicity by many folds and compliance rates decrease. In this context a systemic therapy, which when used concurrent with radiation with favorable toxicity profile is of great importance for improving disease control in locally advanced HNSCC. Anti-epithelial growth factor receptor targeted therapy emerged as a potential treatment option. In recent years many trials were conducted to find the optimum treatment option with the combination of these targeted agents. The initial trials showed excellent results with minimal morbidity and led to great enthusiasm across the globe to incorporate these regimens as a standard of care. However, subsequently many trials failed to maintain such results and now there is little agreement to the initial results achieved with these drugs. Based on the current evidence we cannot recommend the replacement of cisplatin with targeted therapy in concurrent setting. It may be considered in patients with altered renal parameters, hypersensitivity or intolerance to cisplatin. The addition of targeted therapy in addition to chemotherapy in the concurrent setting can’t also be recommended as the benefit is doubtful and is associated with a significant increase in toxicity.

    Full Text Available Mitul D Gandhi, Mark Agulnik Division of Hematology and Oncology, Robert H Lurie Comprehensive Cancer Center, Feinberg School of Medicine, Northwestern University, Chicago, IL, USA Abstract: Squamous-cell cancer of the head and neck is a heterogeneous malignancy with treatment predicated on a multimodality therapy involving surgery, chemotherapy, and radiation. However, this approach results in durable responses in only a subset of patients, and is associated with significant toxicity. In advanced disease, multi-agent platinum-based chemotherapy produces only modest improvements in survival. Increased insight into tumor biology has demonstrated several critical oncogenic pathways offering prospects for targeted therapy that may improve upon the existing treatment strategies. The epidermal growth factor receptor is one such target, and directed therapy with the monoclonal antibody cetuximab has been extensively studied. Lapatinib is an oral agent that targets multiple transmembrane receptors within the epidermal growth factor receptor family, and offers a promising new approach to treatment. This paper reviews the rationale for and clinical activity of lapatinib in squamous-cell cancer of the head and neck.

    Full Text Available Tumor cells become resistant after long-term use of anti-VEGF (vascular endothelial growth factor agents. Our previous study shows that treatment with a VEGF inhibitor (VEGF-Trap facilitates to develop tumor resistance through regulating angiogenesis-related genes. However, the underlying molecular mechanisms remain elusive. Histone modifications as a key epigenetic factor play a critical role in regulation of gene expression. Here, we explore the potential epigenetic gene regulatory functions of key histone modifications during tumor resistance in a mouse Lewis lung carcinoma (LLC cell line. We generated high resolution genome-wide maps of key histone modifications in sensitive tumor sample (LLC-NR and resistant tumor sample (LLC-R after VEGF-Trap treatment. Profiling analysis of histone modifications shows that histone modification levels are effectively predictive for gene expression. Composition of promoters classified by histone modification state is different between LLC-NR and LLC-R cell lines regardless of CpG content. Histone modification state change between LLC-NR and LLC-R cell lines shows different patterns in CpG-rich and CpG-poor promoters. As a consequence, genes with different level of CpG content whose gene expression level are altered are enriched in distinct functions. Notably, histone modification state change in promoters of angiogenesis-related genes consists with their expression alteration. Taken together, our findings suggest that treatment with anti-VEGF therapy results in extensive histone modification state change in promoters with multiple functions, particularly, biological processes related to angiogenesis, likely contributing to tumor resistance development.

    Full Text Available Introduction : Polymorphic variants of MCP-1 and RANTES genes and their protein serum levels have been implicated in the increased risk and severity of several malignancies. However, the subject has not been explored in basal cell carcinoma (BCC patients so far. Aim : To investigate the association between monocyte chemoattractant protein 1 (MCP-1 (–2518 A/G and RANTES (–403 G/A polymorphism and risk and clinical course of BCC. Material and methods : The study group consisted of 150 unrelated patients with BCC and 140 healthy, unrelated, age- and sex-matched volunteers. The polymorphisms were analysed using the amplification refractory mutation system polymerase chain reaction method (ARMS-PCR and single specific primer-polymerase chain reaction (SSP-PCR. Serum cytokine levels were measured with ELISA. Results : The presence of the MCP-1 –2518 GG genotype was statistically more frequent in BCC patients and it increased the risk of BCC (OR = 2.63, p = 0.003. Genotype –330 GG was statistically more common in patients with less advanced tumours (OR = 2.8, p = 0.017. Monocyte chemoattractant protein 1 serum level was statistically higher with GG genotype. In the BCC group MCP-1 serum levels were decreased. Neither polymorphic variants of RANTES nor the chemokine serum concentration differed significantly between the study groups. Conclusions : These findings suggest that –2518 A/G MCP-1 polymorphism may be involved in BCC pathogenesis.

    The frequency of occurrence of relapses and delayed regional metastases in the lymph nodes in the patients with head and neck tumors depending on various combinations of operative and radiotherapy are estimated in the work. It is shown that tumor progression occurs more often in the case of radiotherapy as the only method of treatment. The parameters of general, disease-free and non-metastatic survival were evaluated. In the evaluation of the survival rate, a decrease in disease-free survival in head and neck squamous cell carcinomas patients with radiotherapy treatment was observed. Disease-free survival is better in the patients receiving surgical treatment than in the patients with radiotherapy (log rank test p = 0.043), as well as above disease-free survival in the patients with combination of neoadjuvant radiotherapy and surgery vs neoadjuvant radiotherapy alone (p = 0.042). It is also shown that human papillomavirus is not a risk factor for tumor progression and does not affect the course of the disease.

    To describe the use of a pulse-dose topical 5-fluorouracil (5-FU) treatment regimen in a Pug dog with corneal squamous cell carcinoma (SCC). A 1-year-old, spayed female Pug was evaluated for a corneal perforation of the right eye, which was surgically stabilized with a conjunctival pedicle graft. At the time of medial canthoplasty 7 weeks later, two areas of gray-white discoloration had developed medial and lateral to the graft. Biopsy samples were obtained via superficial keratectomy while under general anesthesia. Definitive diagnosis of corneal SCC was made through histopathological examination of the surgical biopsies. Thoracic radiography and submandibular lymph node cytology revealed no evidence of metastatic neoplasia. Following healing of the corneal biopsy sites, topical 1% 5-FU ointment was applied four times daily for four consecutive days once a month, for six treatment cycles. Twenty-three months after diagnosis, the patient remains visual and comfortable with no evidence of SCC recurrence. Long-term therapy with once daily topical 1% cyclosporine solution was used to manage corneal pigmentation bilaterally. The pulse-therapy 1% 5-FU protocol was a successful, convenient, and cost-effective adjunctive treatment with few adverse effects. © 2014 American College of Veterinary Ophthalmologists.

    Squamous cell carcinoma of the skin (SCCS) is a common malignancy with potentially devastating consequences in patients with locally advanced or metastatic disease. Its rising incidence, primarily a result of an aging population and increased ultraviolet (UV) radiation exposure, characterize an emerging unmet need. A firm understanding of the biology of this disease, likely distinct from that of other squamous malignancies because of the influence of UV radiation, is necessary in the evaluation of treatment paradigms. Careful recognition of high-risk features pertaining to tumor and host characteristics is paramount to proper management. However, a lack of standardization in guidelines in this regard creates a challenge for physicians. Questions persist regarding additional evaluation and treatment for advanced disease such as the roles for sentinel lymph node biopsy and the adjuvant use of radiation and chemotherapy. With respect to advanced disease, multiple combinations of chemotherapy have been tested with variable success, but no rigorous randomized studies have been conducted. In addition, EGFR inhibitors such as cetuximab and erlotinib have displayed antitumor activity and as such, warrant further investigation. In sum, the treatment of locally advanced and metastatic SCCS is a ripe area for clinical investigation. This article summarizes the current understanding of disease biology and emerging questions in the management of this disease.

    Surgery is the mainstay of treatment for oesophageal squamous-cell carcinoma (OSCC) but with poor results. Attempts to improve patient outcome have been made by introducing chemotherapy (CT), radiotherapy (RT), or both (CRT). However, randomized comparisons for all these strategies are not always available. We conducted an extensive literature search for studies comparing surgery with multimodality treatment (i.e. [neo-]adjuvant CT or RT or CRT or definitive CRT). Network meta-analysis was performed in a Bayesian framewor and node-split models were built to assess inconsistency. Twenty-five trials including a total of 3866 OSCC patients were included. Neoadjuvant CRT was associated with the most robust survival advantage across different multimodality treatment options (HR 0.73; 95% credible interval [CrI] 0.63-0.86). Definitive CRT was also significantly more effective than surgery but with greater uncertainties (HR 0.62; 95%CrI 0.41-0.96). Neoadjuvant CT (HR 0.90; 95%CrI 0.76-1.07) and adjuvant CRT (HR 1.00; 95%CrI 0.70-1.40) are associated with a non-significant benefit. To date, neoadjuvant CRT seems to represent the best approach to maximize the benefit of a multimodality approach. Copyright © 2017 Elsevier B.V. All rights reserved.

    Caroline Randrup Hansen

    2017-02-01

    Full Text Available In recent years, targeted therapies have proven beneficial in terms of progression-free survival (PFS and overall survival (OS in the treatment of metastatic renal cell carcinoma (mRCC. The tyrosine kinase inhibitors (TKIs sorafenib and sunitinib are included in international clinical guidelines as first-line and second-line therapy in mRCC. Hypertension is an adverse effect of these drugs and the degree of hypertension associates with the anti-tumour effect. Studies have compared newer targeted drugs to sorafenib and sunitinib in terms of PFS, OS, quality of life and safety profiles. Phase III studies presented promising response rates and acceptable safety profiles of axitinib and tivozanib compared to sorafenib, and a phase II study reported greater efficacy using a combination of bevacizumab and IFN-α compared to sunitinib. Treatment with nintedanib exhibited a notably low prevalence of hypertension compared to sunitinib. The use of sorafenib and sunitinib are challenged by new drugs, but do not appear likely to be substituted in the near future. To clarify whether newer targeted drugs should replace sorafenib and sunitinib, more research is needed. This manuscript reviews the current utility and adverse effects of sorafenib and sunitinib and newer targeted therapies in the treatment of mRCC.

Design: Prospective, noncomparative case series. Participants: Fifteen patients with histological evidence CIN or SCC of the conjunctiva and cornea were identified by tumor biopsy. Methods: All patients clinically evident of CIN, or SCC were evaluated, with maximum 30 months of follow-up were treated with pulsed dosing of 1% 5-FU. Treatment cycles were defined as four times per day for 4 days using the medication followed by 30 days without medication. The number of initial treatment was six cycles. Results: The mean age of the 15 patients was 50.8 years (range 25–78 years. Excision biopsy proved seven cases as CIN, and eight cases as locally invasive SCC. All patients remained disease free with a mean follow-up of 14.53 months (range 6-30 months. Additional chemotherapy was given after the initial treatment cycles, only for one case. 5-FU caused mild temporary local irritation, but no long-term intraocular or extra ocular complications. Conclusions: Adjuvant 1% topical 5-FU appears to be effective in the prevention of recurrence of conjunctival or corneal CIN and SCC after excision biopsy. Our results indicate that at least six cycles of topical 1% 5-FU is required to prevent local recurrence in the long term. It is well-tolerated and an effective method of treatment. No complications that would preclude use of our dose regimen were noted.Keywords: chemotherapy, fluorouracil, neoplasia, treatment cycles

    Given the paucity of esophageal small cell carcinoma (SCC) cases, there are few large studies evaluating this disease. In this study, the National Cancer Data Base (NCDB) was utilized to analyze the clinical features, treatment, and survival of patients with esophageal SCC in a large, population-based dataset. We selected patients diagnosed with esophageal SCC from 1998 to 2011. Patients were identified as having no treatment, chemotherapy alone, radiation ± sequential chemotherapy, concurrent chemoradiation, and esophagectomy ± chemotherapy and/or radiation. Overall survival (OS) was analyzed using the Kaplan-Meier method and compared using the log-rank test. Multivariate Cox regression analysis was conducted to identify factors associated with OS. A total of 583 patients were identified. Most patients had stage IV disease (41.7%). Regarding treatment selection, chemoradiation was the most commonly utilized for patients with nonmetasatic disease, whereas chemotherapy alone was most common for metastatic patients. Esophagectomy (median survival 44.9 months with 3 year OS 50.5%) was associated with the best OS for patients with localized (node-negative) disease compared with chemotherapy alone (p < 0.001) or chemoradiation (p = 0.01). For locoregional (node-positive) disease, treatment with chemoradiation resulted in a median survival of 17.8 months and a 3 year OS 31.6%. On multivariate analysis, treatment with chemotherapy alone (p = 0.003) was associated with worse OS while esophagectomy (p = 0.04) was associated with improved OS compared to chemoradiation. Esophageal SCC is an aggressive malignancy with most patients presenting with metastatic disease. Either esophagectomy or chemoradiation as part of multimodality treatment appear to improve OS for selected patients with nonmetastatic disease. © 2016 International Society for Diseases of the Esophagus.

RT-PCR technology was applied to detect the expression of ELF5 mRNA in epithelial ovarian carcinoma (n=49), borderline ovarian epithelial tumor (n=19), benign ovarian epithelial tumor (n=31) and normal ovarian tissues (n=40). Then, we transfected recombinant plasmid pcDNA3.1‑ELF5+EGFP into human ovarian carcinoma SKOV3 cells (recombinant plasmid group) in vitro and screened out stably transfected cells to conduct multiplication culture. Western blot analysis was performed to detect the expression of ELF5 protein in the different groups. Flow cytometry was employed to detect cell apoptosis and cycles. ELF5 mRNA in epithelial ovarian carcinoma and borderline ovarian epithelial tumor tissues were significantly lower (Povarian epithelial tumor and normal ovarian tissues. ELF5 protein expression in the cells of recombinant plasmid group was significantly higher compared with empty plasmid and blank control groups. The capacity of cell reproductive recombinant plasmid group at each time point decreased (Povarian carcinoma SKOV3 cells and promoted apoptosis of human ovarian carcinoma SKOV3 cells inhibiting their growth and invasive capacity; and thus providing a new approach to gene treatment of ovarian carcinoma.

    Purpose: We performed a comparative planning study among High Dose Rate (HDR) brachytherapy, superficial electrons, Volume Modulated Arc Therapy (VMAT), and Helical IMRT (Tomotherapy) for squamous cell carcinoma of the abdominal wall with consideration for the underlining bowel. Methods: A 69-year old female presented with squamous cell carcinoma protruding 8mm beyond the anterior skin surface of the midabdomen was considered for treatment. The patient had a ventral hernia which resulted in the reduction of the abdominal wall thickness and the adjacent small bowel being the dose limiting structure. Four plans were generated using different treatment modalities: a) an enface electron field (eMC, Eclipse v. 11), b) Tomotherapy (HI-Art II v.5.0.5), c) VMAT (Acuros, Eclipse v. 11), and d) HDR using a Freiburg applicator (Oncentra v. 4.3). The following plan objectives were used for all four plans: for the CTV target, V90% ≥90% (61.8Gy2/2).For the small bowel, D0.1cc < 56.2 Gy2/2 was a hard constraint and expressed as a percentage of the prescription for comparison to demonstrate the dose fall-off achieved among the modalities.For HDR, V200% <0.1cc was an additional constraint. Multiple dosimetric parameters, including those listed above, were compared among the four modalities. Results: The HDR plan showed comparable target coverage compared to the Tomotherapy plan and better coverage compared to the electron plan. Small bowel doses (D0.1cc) were lower in HDR plan compared to Tomotherapy, electron, & VMAT plans (88.8%, 89.6%, 90.9%, & 96.6%). Integral dose to the whole body (V5%) was much higher for HDR, VMAT, and Tomotherapy when compared to electron plan by factors of seven, eight, and ten, respectively. After reviewing all treatment modalities, the physician selected HDR owing to better control of the small bowel dose while maintaining adequate target coverage. Conclusion: This case study demonstrated HDR can successfully treat superficial lesions with superior

    Immunotherapy has produced durable clinical benefit in patients with metastatic renal cell cancer (RCC). In the past, patients treated with interferon-alpha (IFN) and interleukin-2 (IL-2) have achieved complete responses, many of which have lasted for multiple decades. More recently, a large number of new agents have been approved for RCC, several of which attack tumor angiogenesis by inhibiting vascular endothelial growth factors (VEGF) and VEGF receptors (VEGFR), as well as tumor metabolism, inhibiting the mammalian target of rapamycin (mTOR). Additionally, a new class of immunotherapy agents, immune checkpoint inhibitors, is emerging and will play a significant role in the treatment of patients with RCC. Therefore, the Society for Immunotherapy of Cancer (SITC) convened a Task Force, which met to consider the current role of approved immunotherapy agents in RCC, to provide guidance to practicing clinicians by developing consensus recommendations and to set the stage for future immunotherapeutic developments in RCC.

    Epidemiological studies support a link between cumulative sun exposure and cutaneous squamous cell carcinoma (SCC) development. However, the presumed effects of extended ultraviolet light B (UVB) exposure on tumorigenesis in the sexes have not been formally investigated. We examined differences in ultimate tumorigenesis at 25 weeks in mice exposed to UVB for either 10 or 25 weeks. Additionally, we investigated the effect of continued UVB exposure on the efficacy of topical treatment with anti-inflammatory (diclofenac) or antioxidant (C E Ferulic or vitamin E) compounds on modulating tumorigenesis. Vehicle-treated mice in the 25-week UVB exposure model exhibited an increased tumor burden and a higher percentage of malignant tumors compared to mice in the 10-week exposure model, which correlated with increases in total and mutant p53-positive epidermal cells. Only topical diclofenac decreased tumor number and burden in both sexes regardless of UVB exposure length. These data support the commonly assumed but not previously demonstrated fact that increased cumulative UVB exposure increases the risk of UVB-induced SCC development and can also affect therapeutic efficacies. Our study suggests that cessation of UVB exposure by at-risk patients may decrease tumor development and that topical NSAIDs such as diclofenac may be chemo preventive.

    The purpose of this study was to determine the safety, effectiveness, and feasibility of microwave ablation (MWA) of small renal cell carcinomas (RCCs) in selected patients. Institutional review board and informed consent were obtained. From December 2007 to January 2009, 12 patients (8 male, 4 female) were enrolled in a treatment group, in which percutaneous MWA of small RCCs was performed under contrast-enhanced ultrasound guidance. The tumors were 1.7-2.9 cm in diameter (mean diameter, 2.0 cm).Therapeutic effects were assessed at follow-up with computed tomography. All patients were followed up for 3-14 months (mean, 6 months) to observe the therapeutic effects and complications (according to SIR classification). Assessment was carried out with CT imaging. No severe complications or unexpected side effects were observed after the MWA procedures. In all cases technical success was achieved. Clinical effectiveness was 100%; none of the patients showed recurrence on imaging. In conclusion, our preliminary results support the use of MWA for the treatment of small renal tumors. This technology can be applied in select patients who are not candidates for surgery, as an alternative to other ablative techniques.

    This study characterized the infiltration of primary tumors along the intrinsic and extrinsic muscles of the tongue in oral tongue squamous cell carcinoma (OTSCC), to create a new surgical strategy that is suitable for most stages. A preliminary evaluation of this novel surgical approach was also conducted. An anatomic study of macroscopic specimens from 10 human cadavers and 100 OTSCC patients was conducted. The anatomic characteristics of the primary tumors and the origin and distribution of fibers of the intrinsic and extrinsic tongue muscles were observed and measured. After initial treatment with curative intent, the 100 patients were regularly followed-up with clinical examination and imaging. Based on the anatomic characteristics of the primary tumors and tongue muscles, a new surgical approach was developed, and was described as muscle anatomy tongue surgery (MATS). MATS proved suitable for almost all stages of OTSCC. According to the morphology of the invasive tumor front, the 100 cases were divided into four types. The rate of 2-year local disease control was 98%, locoregional control 86%, disease-free survival 85%, and overall survival 89%. Tongue functions were perfectly recovered in more than 60% of the patients. Application of the principles of MATS to the treatment of OTSCC proved suitable for almost all stages of the disease. MATS is a novel surgical technique that may improve outcomes in tongue cancer surgery. Copyright © 2015 European Association for Cranio-Maxillo-Facial Surgery. Published by Elsevier Ltd.

    Full Text Available We retrospectively analyzed 14 patients with locally advanced squamous cell carcinoma of ethmoid sinus (LASCC-ES for the feasibility of anterior craniofacial resection (ACFR. Ethmoid cancer treatment comprised alternating chemoradiotherapy (ALCRT; n = 1, concomitant radiotherapy and intra-arterial cisplatin (RADPLAT; n = 4 and ACFR (n = 9. The 3- and 5-year overall survival (OS rates of patients were 47.6 and 39.6%, respectively. The 3-year local control (LC rates of chemoradiotherapy (CRT; ALCRT and RADPLAT (n = 5 and ACFR (n = 9 groups were 0 and 66.7% (p = 0.012, respectively. The 3-year progression-free survival (PFS rate of the CRT and ACFR groups were 0 and 55.6% (p = 0.018, respectively. The 3-year OS rate of the CRT and ACFR groups were 0 and 76.2% (p = 0.005, respectively. Postoperative pathological examinations confirmed positive margins in 3 (33% of 9 cases. The 3-year LC and PFS rates of cases (n = 3 with positive surgical margins were significantly poorer than those of cases (n = 6 with negative surgical margins. Although ACFR for LASCC-ES is a feasible treatment, cases with positive surgical margins were more prone to local relapse. Therefore, surgical safety margins should be thoroughly assessed.

    Full Text Available PURPOSE: A great number of small renal lesions have now been detected. Nowadays, partial nephrectomy has more frequently been adopted for surgical treatment of earlier stage disease. Previous studies have associated patient, institutional, and health care system factors with surgery type. The aim of this study was to compare the diagnosis and treatment of renal cell carcinoma (RCC according to hospital type, public versus private, in our country. MATERIALS AND METHODS: We retrospectively evaluated 183 patients with RCC who underwent radical nephrectomy or nephron-sparing surgery between 2003 and 2007 in two hospitals, one private and one public. Patient demographic, clinical, surgery, and pathologic characteristics were analyzed. RESULTS: The radical nephrectomy rate was higher at the public hospital than at the private hospital (75% vs. 57%, p = 0.008. Overall, patients at the public hospital presented larger tumors than did the patients who were cared for privately. Furthermore, small renal masses were significantly more prevalent in private care (57.8% vs. 28.3%. Patients at the public hospital showed a higher incidence of capsular invasion (p = 0.008, perirenal fat invasion (p < 0.01, lymph node involvement (p < 0.001, and a lower incidence of initial tumors. pT1 tumors were reported in 41% of patients at the public hospital and in 72% at the private hospital (p < 0.001. CONCLUSION: Patients with RCC cared for at our public referral hospital showed a more advanced stage than RCC treated at the private institution.

    Full Text Available Background: Few cases of pouch-related cancers have been reported in ulcerative colitis (UC, and squamous cell carcinoma (SCC is very rare. Method: A systematic review of the literature was performed to identify all unequivocal cases of pouch-related SCC in UC patients. Results: Eight cases of SCC developing after ileal pouch-anal anastomosis (IPAA have been observed since 1978. Two arose from the pouch mucosa and 6 from below. The pooled cumulative incidence of SCC is below 0.06% after IPAA. Many patients had neoplasia on the preoperative specimen, but squamous metaplasia of the pouch or anorectal mucosa may have an important role in SCC. These patients are rarely offered chemoradiation therapy and the outcome is poor. Selected patients with SCC located close to the pouch outlet can be treated with chemoradiation prior to consideration of surgery and salvage their pouch. A chemoradiation regimen is suggested to avoid pouch excision in these patients. Conclusions: SCC is rare after pouch surgery but associated with extremely poor survival. Very low SCC can be managed with chemoradiation treatment, preserving the pouch and avoiding surgery, even in older patients. The role of pouch metaplasia, surveillance frequency, and treatment modalities after IPAA need further studying.

    The optimal treatment of patients with T3 laryngeal carcinoma is controversially challenged by open partial laryngectomies (OPL), transoral laser microsurgery (TLM) and radiation therapy alone (RT) or combined with chemotherapy (ChRT). Treatment guidelines, experts' opinions and clinical studies are highly contradictory. The aim of this study is to compare the primary outcomes of the available treatment methods and identify the sources of variance among studies. A review of the literature published in the time period 2003-2015 was conducted via the PubMed database (www.pubmed.org) and Scopus database (www.scopus.com) with the search terms "T3 laryngeal squamous cell cancer treatment". Data from clinical studies involving patients with T3 laryngeal cancer (n > 10) subjected to TLM, OPL, ChRT or RT, were pooled. In the absence of controlled studies, prospective and retrospective clinical trials with minimum 5-year follow-up were acceptable, provided that they included a description of patient eligibility criteria, so as to exclude studies with serious selection bias. Literature lacks studies with homogenous populations regarding TNM staging, preoperative/postoperative treatment or anatomical subsite. This raises substantial controversies and prohibits the conduction of a meta-analysis. Data for qualitative analysis were pooled from 8 studies (n = 1226). OPL and TLM both offer patients high survival and organ preservation rates. Preoperative induction chemotherapy seems to significantly compromise overall survival. Multicenter studies referring to homogenous populations, at least regarding staging and anatomical subsite, are needed. No safe conclusions can be drawn given the heterogeneity in patient cohorts, study design and evaluation of results in the existing literature.

    The worldwide incidence of kidney cancer is estimated at 337,860 new cases per year in the International Agency for Research on Cancer's GLOBOCAN 2012 update, with an estimated 143,369 deaths annually. Over the past 10 years, there have been significant advances in the treatment of advanced/metastatic renal cell carcinoma, including the development of targeted therapies. Currently recommended first-line treatments include sunitinib, temsirolimus, bevacizumab plus interferon, and pazopanib, or high-dose interleukin-2 or sorafenib for selected patients. Recommended second-line treatments include all of the above agents, as well as everolimus and axitinib. Unfortunately, combination therapies have generally resulted in increased toxicity and little improvement in efficacy. Recent studies focused on identification of predictive biomarkers for responses to specific targeted therapies and have not been successful to date. Despite recent advances in targeted treatment for metastatic renal cell carcinoma, important questions regarding biomarkers of efficacy, and optimal combination and sequencing of agents remain to be answered. This paper reviews literature concerned with first-and second-line treatment of metastatic renal cell carcinoma and will discuss key issues in Latin America.

    The genomic alterations identified in head and neck squamous cell carcinoma (HNSCC) tumors have not resulted in any changes in clinical care, making the development of biomarker-driven targeted therapy for HNSCC a major translational gap in knowledge. To fill this gap, we used 59 molecularly characterized HNSCC cell lines and found that mutations of AJUBA, SMAD4 and RAS predicted sensitivity and resistance to treatment with inhibitors of polo-like kinase 1 (PLK1), checkpoint kinases 1 and 2, and WEE1. Inhibition or knockdown of PLK1 led to cell-cycle arrest at the G 2 /M transition and apoptosis in sensitive cell lines and decreased tumor growth in an orthotopic AJUBA-mutant HNSCC mouse model. AJUBA protein expression was undetectable in most AJUBA-mutant HNSCC cell lines, and total PLK1 and Bora protein expression were decreased. Exogenous expression of wild-type AJUBA in an AJUBA-mutant cell line partially rescued the phenotype of PLK1 inhibitor-induced apoptosis and decreased PLK1 substrate inhibition, suggesting a threshold effect in which higher drug doses are required to affect PLK1 substrate inhibition. PLK1 inhibition was an effective therapy for HNSCC in vitro and in vivo. However, biomarkers to guide such therapy are lacking. We identified AJUBA, SMAD4 and RAS mutations as potential candidate biomarkers of response of HNSCC to treatment with these mitotic inhibitors. Copyright © 2017 Elsevier B.V. All rights reserved.

    Background - Squamous cell carcinoma of the esophagus is still a difficult tumor to treat with very poor prognosis. Aim - To compare the response to teletherapy treatment (external beam radiotherapy) alone versus teletherapy combined with brachytherapy for patients with advanced squamous cell carcinoma of the esophagus. Methods - Were studied 49 patients with advanced squamous cell carcinoma of the esophagus on clinical stage III (TNM-1999). They were separated into two groups. The first, underwent radiation therapy alone with linear accelerator of particles, average dose of 6000 cGy and the second to external beam radiation therapy at a dose of 5040 cGy combined with brachytherapy with Iridium 192 at a dose of 1500 cGy. Brachytherapy started one to two weeks after the end of teletherapy, and it was divided into three weekly applications of 500 cGy. Age, gender, race, habits (smoking and drinking), body mass index (BMI), complications with treatment benefits (pain relief and food satisfaction) and survival were analyzed. Results - The quality of life (food satisfaction, and pain palliation of dysphagia) were better in the group treated with external beam radiation therapy combined with brachytherapy. Survival was higher in the brachytherapy combined with external beam radiation therapy alone. Conclusion - Although the cure rate of squamous cell cancer of the esophagus is almost nil when treated with irradiation alone, this therapy is a form of palliative treatment for most patients in whom surgical contraindication exists.

    To evaluate the clinical outcomes of patients who underwent radiation therapy with or without targeted molecular therapy for the treatment of spinal metastasis from renal cell carcinoma (RCC). A total of 28 spinal metastatic lesions from RCC patients treated with radiotherapy between June 2009 and June 2015 were retrospectively reviewed. Thirteen lesions were treated concurrently with targeted molecular therapy (concurrent group) and 15 lesions were not (nonconcurrent group). Local control was defined as lack of radiographically evident local progression and neurological deterioration. At a median follow-up of 11 months (range, 2 to 58 months), the 1-year local progression-free rate (LPFR) was 67.0%. The patients with concurrent targeted molecular therapy showed significantly higher LPFR than those without (p = 0.019). After multivariate analysis, use of concurrent targeted molecular therapy showed a tendency towards improved LPFR (hazard ratio, 0.13; 95% confidence interval, 0.01 to 1.16). There was no difference in the incidence of systemic progression between concurrent and nonconcurrent groups. No grade ≥2 toxicities were observed during or after radiotherapy. Our study suggests the possibility that concurrent use of targeted molecular therapy during radiotherapy may improve LPFR. Further study with a large population is required to confirm these results.

    The case of a 70-year-old woman with progressive renal cell carcinoma (RCC) metastatic invasion of a L3 vertebral hemangioma treated by dual percutaneous radiofrequency ablation (RFA) and vertebroplasty is reported. The patient was surgically treated for RCC in 2001. Chemotherapy and immunotherapy were introduced in 2013 for ovarian, bladder and cerebral metastatic disease. An asymptomatic L3 benign hemangioma was noticed at this time. One-year CT and MRI follow-up studies demonstrated a nodular isolated soft tissue lesion involving the anterior edge of the hemangioma. Percutaneous treatment consisted of a L3 vertebral body unipedicular approach to perform a biopsy, RFA with a navigational bipolar RFA device and vertebroplasty using high viscosity cement. Histopathological examination confirmed metastasis of RCC. The 5-month spinal MRI and CT examinations demonstrated complete disappearance of the tumor. Published by the BMJ Publishing Group Limited.

    Most of the patients reached by lungs cancer are not operable at the time of diagnosis. The radio chemotherapy has not been superior to the radical radiotherapy. The bad results could be explained by the following causes: provinces population that consults too late, delays in the treatment start-up, inadequate support during the treatment for lack of economic means. The results of oncological treatments turned out to be superior to the symptomatic treatments. (N.C.)

    2013-01-01

    Full Text Available Metastatic renal cell carcinoma of the bone occurs at a high rate, and the prognosis is poor. In general, total en bloc spondylectomy is considered when there is only one vertebral metastasis and the primary disease is treated. However, palliative surgery is selected when the primary disease is not being treated or metastasis occurs to an important organ. We encountered a patient in whom lung and vertebra metastases were already present at the time of the first examination at our department and the prognosis was considered poor. However, molecular targeted therapy was markedly effective and enabled 2-stage total en bloc spondylectomy. As of one year after total en bloc spondylectomy, the condition has improved to cane gait, and surgery for lung metastasis is planned. Molecular target drugs might markedly change the current therapeutic strategy for renal cell carcinoma.

    To investigate the effects of anti-infection treatment on the expressions of antigen-presenting-related membrane-surface molecules HLA-DR and CD86 in dendritic cells (DCs) in rabbit buccal VX2 squamous cell carcinoma tissue complicated with local inflammation. Rabbit buccal VX2 squamous cell carcinoma with local inflammation models that were established by inflammation was induced by inoculation VX2 tumor, mechanical trauma, and drinking of milk with high sugar viscosity. The animals were divided into four groups. Group A (n=12): rabbit buccal VX2 squamous cell carcinoma with local inflammation, procaine penicillin was intramuscularly given, and tinidazole tablets were given by gavage for three consecutive days. Group B (n = 12): rabbit buccal VX2 squamous cell carcinoma with local inflammation, normal saline was intramuscularly given, and aspirin were given by gavage for three consecutive days. Group C (n = 12): rabbit buccal VX2 squamous cell carcinoma with local inflammation, normal saline was given intramuscularly and by gavage for three consecutive days. Group D (n = 10): rabbit buccal VX2 squamous cell carcinoma, normal saline was given intramuscularly and by gavage for three consecutive days. All the rabbits were sacrificed for collection of tumor specimens, and the expression levels of membrane-surface HLA-DR and CD86 in DCs of tumor specimens were detected viaflow cytometry. The positive expression rate of HLA-DR and the double positive expression rate of HLA-DR and CD86 were group A > group D > group B > group C. The positive expression rate of CD86 were group A > group D > group B and group C (P < 0.05). Anti-infection treatment significantly increased the expressions of HLA-DR and CD86 in DCs of rabbit buccal VX2 squamous cell carcinoma tissue complicated with local inflammation.

    Full Text Available The major development of the past decade in the first-line treatment of recurrent and/or metastatic squamous cell carcinoma of the head and neck (R/M SCCHN was the introduction of cetuximab in combination with platinum plus 5-fluorouracil chemotherapy (CT, followed by maintenance cetuximab (the “EXTREME” regimen. This regimen is supported by a phase 3 randomized trial and subsequent observational studies, and it confers well-documented survival benefits, with median survival ranging between approximately 10 and 14 months, overall response rates between 36 and 44%, and disease control rates of over 80%. Furthermore, as indicated by patient-reported outcome measures, the addition of cetuximab to platinum-based CT leads to a significant reduction in pain and problems with social eating and speech. Conversely, until very recently, there has been a lack of evidence-based second-line treatment options, and the therapies that have been available have shown low response rates and poor survival outcomes. Presently, a promising new treatment option in R/M SCCHN has emerged: immune checkpoint inhibitors (ICIs, which have demonstrated favorable results in second-line clinical trials. Nivolumab and pembrolizumab are the first two ICIs that were approved by the US Food and Drug Administration. We note that the trials that showed benefit with ICIs included not only patients who previously received ≥1 platinum-based regimens for R/M SCCHN but also patients who experienced recurrence within 6 months after combined modality therapy with a platinum agent for locally advanced disease. In this review, we outline the available clinical and observational evidence for the EXTREME regimen and the initial results from clinical trials for ICIs in patients with R/M SCCHN. We propose that these treatment options can be integrated into a new continuum of care paradigm, with first-line EXTREME regimen followed by second-line ICIs. A number of ongoing clinical trials

    Full Text Available Several immune-related markers have been implicated in basal cell carcinoma (BCC pathogenesis. The BCC inflammatory infiltrate is dominated by Th2 cytokines, suggesting a specific state of immunosuppression. In contrast, regressing BCC are characterized by a Th1 immune response with IFN-γ promoting a tumor suppressive activity. IL-23/Th17-related cytokines, as interleukin (IL-17, IL-23 and IL-22, play a significant role in cutaneous inflammatory diseases, but their involvement in skin carcinogenesis is controversial and is poorly investigated in BCC. In this study we investigated the expression of IFN-γ, IL-17, IL-23 and IL-22 cytokines in BCC at the protein and mRNA level and their modulation during imiquimod (IMQ treatment or photodynamic therapy (PDT. IFN-γ, IL-17, IL-23 and IL-22 levels were evaluated by immunohistochemistry and quantitative Real Time PCR in 41 histopathologically-proven BCCs (28 superficial and 13 nodular from 39 patients. All BCC samples were analyzed at baseline and 19 of 41 also during medical treatment (9 with IMQ 5% cream and 10 with MAL-PDT. Association between cytokines expression and clinico-pathological variables was evaluated. Higher levels of IFN-γ, IL-17, IL-23 and IL-22 were found in BCCs, mainly in the peritumoral infiltrate, compared to normal skin, with the expression being correlated to the severity of the inflammatory infiltrate. IFN-γ production was higher in superficial BCCs compared to nodular BCCs, while IL-17 was increased in nodular BCCs. A significant correlation was found between IFN-γ and IL-17 expression with both cytokines expressed by CD4+ and CD8+ T-cells. An increase of all cytokines occurred during the inflammatory phase induced by IMQ and at the early time point of PDT treatment, with significant evidence for IFN-γ, IL-23, and IL-22. Our results confirm the role of IFN-γ and support the involvement of IL-23/Th17-related cytokines in BCC pathogenesis and in the inflammatory response

    Full Text Available Abstract Background Aggressive non-melanoma skin cancer (deeply infiltrating, recurrent, and morphea form lesions are therapeutically challenging because they require considerable tissue loss and may demand radical disfiguring surgery. Interferons (IFN may provide a non-surgical approach to the management of these tumors. The aim of this work was to evaluate the effect of a formulation containing IFNs-α and -γ in synergistic proportions on patients with recurrent, advanced basal cell (BCC or squamous cell skin carcinomas (SCSC. Methods Patients with extensive, recurrent, resistant to other procedures BCC or SCSC received the IFN formulation peri- and intralesionally, three times per week for 3 weeks. They had been previously treated with surgery and/or radiotherapy or chemotherapy. Thirteen weeks after the end of treatment, the original lesion sites were examined for histological evidence of remaining tumor. Results Sixteen elder (median 70 years-old patients were included. They beared 12 BCC and 4 SCSC ranging from 1.5 to 12.5 cm in the longest dimension. At the end of treatment 47% CR (complete tumor elimination, 40% PR (>30% tumor reduction, and 13% stable disease were obtained. None of the patients relapsed during the treatment period. The median duration of the response was 38 months. Only one patient with complete response had relapsed until today. Principal adverse reactions were influenza-like symptoms well known to occur with interferon therapy, which were well tolerated. Conclusion The peri- and intralesional combination of IFNs-α and -γ was safe and showed effect for the treatment of advanced, recurrent and resistant to previous treatments of BCC and SCSC in elder patients. This is the first report of such treatment in patients with advance non-melanoma skin cancer. The encouraging result justifies further confirmatory trials.

    Merkel cell carcinoma is a rare aggressive neuroendocrine carcinoma of the skin predominantly affecting elderly Caucasians. It has a high rate of local recurrence and regional lymph node metastases. It is associated with a poor prognosis. Complete spontaneous regression of Merkel cell carcinoma has been reported but is a poorly understood phenomenon. Here we present a case of complete spontaneous regression of metastatic Merkel cell carcinoma demonstrating a markedly different pattern of events from those previously published.

    Purpose: To review the University of Iowa experience with intensity-modulated radiotherapy (IMRT) in the treatment of head-and-neck squamous cell carcinoma. Methods and Materials: From October 1999 to April 2004, 151 patients with head-and-neck squamous cell carcinoma were treated with IMRT for curative intent. One patient was lost to follow-up 2 months after treatment and therefore excluded from analysis. Of the remaining 150 patients, 99 were treated with definitive IMRT, and 51 received postoperative IMRT. Sites included were nasopharynx, 5; oropharynx, 56; larynx, 33; oral cavity, 29; hypopharynx, 8; nasal cavity/paranasal sinus, 8; and unknown primary, 11. None of the patients treated with postoperative IMRT received chemotherapy. Of 99 patients who had definitive IMRT, 68 patients received concurrent cisplatin-based chemotherapy. One patient received induction cisplatin-based chemotherapy, but no concurrent chemotherapy was given. Three clinical target volumes (CTV1, CTV2, and CTV3) were defined. The prescribed doses to CTV1, CTV2, and CTV3 in the definitive cohort were 70-74 Gy, 60 Gy, and 54 Gy, respectively. For high-risk postoperative IMRT, the prescribed doses to CTV1, CTV2, and CTV3 were 64-66 Gy, 60 Gy, and 54 Gy, respectively. For intermediate-risk postoperative IMRT, the prescribed doses to CTV1, CTV2, and CTV3 were 60 Gy, 60 Gy, and 54 Gy. Results: The median follow-up was 18 months (range, 2-60 months). All living patients were followed for at least 6 months. There were 11 local-regional failures: 7 local failures, 3 regional failures, and 1 failure both in the primary tumor and regional lymph node. There were 16 patients who failed distantly, either with distant metastasis or new lung primaries. The 2-year overall survival, local progression-free survival, locoregional progression-free survival, and distant disease-free survival rates were 85%, 94%, 92%, and 87%, respectively.

    Purpose: Metastatic cancer to the brain is a major problem for the patients with bronchogenic carcinoma, and most of these patients have a limited survival expectancy. To increase tumor control and/or to decrease late morbidity with possible shortening in over-all treatment period, multiple daily fraction technique for brain metastasis was performed. The author represented the results of accelerated fractionation radiotherapy in patients with brain metastases from non-small cell lung cancer. Materials and Methods: Twenty-six patients with brain metastases from non-small cell lung cancer between 1991 and 1993 received brain radiotherapy with a total dose of 48 Gy, at 2 Gy per fraction, twice a day with a interfractional period of 6 hours, and delivered 5 days a week. The whole brain was treated to 40 Gy and boost dose escalated to 8 Gy for single metastatic lesion by reduced field. Twenty-four of the 26 patients completed the radiotherapy. Radiotherapy was interrupted in two patients suggesting progressive intracerebral disease. Results: This radiotherapy regimen appears to be comparable to the conventional schema in relief from symptoms. Three of the 24 patients experienced nausea and or vomiting during the course of treatment because of acute irradiation toxicity. The author observed no excessive toxicity with escalating dose of irradiation. An increment in median survival, although not statistically significant (p>0.05), was noted with escalating doses(48 Gy) of accelerated fractionation (7 months) compared to conventional treatment(4.5 months). Median survival also increased in patients with brain solitary metastasis(9 months) compared to multiple extrathoracic sites(4 months), and in patients with good performance status(9 months versus 3.5 months), they were statistically significant(p<0.01). Conclusion: The increment in survival in patients with good prognostic factors such as controlled primary lesion, metastasis in brain only, and good performance status

    Full Text Available Basal cell carcinoma is the most common malignant neoplasm of the skin of the face in old, caucasian humans. The tumour growth slow and rarely has metastases. The clinical presentation is different. The main method for treating is radical surgical excision, but if the tumour is very big or there are metastases, there is a very effective target therapy with the peroral capsules Vismodegib 150mg. In this case we introduce a patient whit cancer of upper lip of preoperative target therapy whit Vismodegib 150mg, which destroy the tumour cells and help us to make cosmetic surgical excision.

    Three hundred and four patients with squamous cell carcinomas of the oral cavity were treated at the Finsen Institute in cooperation with the ENT-surgical departments between 1978 and 1982. The primary treatment consisted of radiotherapy alone in 74%, surgery alone in 4%, and a combination of radiotherapy and surgery in 15% of the patients. 2% received other treatment (cryotherapy), 5% did not complete the planned radiotherapy, and 1% were not treated at all. Of 203 patients with tumour remnant or first recurrence, 45% were operated, 2% received radiotherapy, and 2% combined treatment. This treatment strategy made 38% of the patients free of disease in the follow-up period (3 1/2 to 8 years) or until the patients died from other causes. Fifty-nine percent of the patients died from their oral carcinomas. Tumour size (T), lymph node status (N), and tumour stage were as expected important prognostic factors. (orig.)

    New targeted therapeutics for metastatic renal cell carcinoma (mRCC) enable an increment in progression-free survival (PFS) ranging from 2 to 6 months. Compared with best supportive care, everolimus demonstrated an additional PFS of 3 months in patients with mRCC whose disease had progressed on sunitinib and/or sorafenib. The only targeted therapy for mRCC currently reimbursed in Serbia is sunitinib. The aim of this study was to estimate the cost-effectiveness and the budget impact of the introduction of everolimus in Serbia in comparison to best supportive care, for mRCC patients refractory to sunitinib. A Markov model was designed corresponding with Serbian treatment protocols. A health care payer perspective was taken, including direct costs only. Treated and untreated cohorts were followed up over 18 cycles, each cycle lasting 8 weeks, which covered the lifetime horizon of mRCC patients refractory to the first-line treatment. Annual discounted rates of 1.5% for effectiveness and 3% for costs were applied. Transitions between health states were modeled by time-dependent probabilities extracted from published Kaplan-Meier curves of PFS and overall survival (OS). Utility values were obtained from the appraisals of other mRCC treatments. One-way and probabilistic sensitivity analyses were done to test the robustness and uncertainty of the base-case estimate. Lastly, the potential impacts of everolimus on the overall health care expenditures on annual and 4-year bases were estimated in the budget-impact analysis. The incremental cost-effectiveness ratio for everolimus was estimated at €86,978 per quality-adjusted life-year. Sensitivity analysis identified the hazard multiplier, a statistical approximator of OS gain, as the main driver of everolimus cost-effectiveness. Furthermore, probabilistic sensitivity analyses revealed a wide 95% CI around the base-case incremental cost-effectiveness ratio estimate (€32,594-€425,258 per quality-adjusted life

    Full Text Available Oral cancer is a potentially fatal disease that constitutes an important portion of tumors that occur in the head and neck region. Oral cancer can affect overall and mental health, appearance, employment, social life, and family living. The disease can cause serious changes in the functioning of the upper aero digestive tract that affects the quality of life in patients. The use of conventional treatment modalities (surgery, radiation, and/or chemotherapy depends on tumor respectability and location as well as whether an organ preservation approach is feasible. However, their role in oral cancer treatment is nonselective and can cause damage to normal tissue. In particular, chemo radiotherapy is associated with systemic toxicities that often reduce patient compliance and prevent timely completion of therapy. The development of targeted therapies to target select pathways involved in carcinogenesis, potentially decrease systemic toxicities and morbidities associated with cancer burden and hence improve the prognosis in cancer patients. In the present article, the role of various targeted molecules in the treatment of oral cancer is discussed.

    Hepatocellular carcinoma (HCC) is the fifth most common neoplasm and the third leading cause of cancer-related deaths worldwide. Cirrhosis, most often due to viral hepatitis, is the predominant risk factors for HCC and geographical differences in both risk factors and incidence are largely due to epidemiological variations in hepatitis B and C infection. Hepatic function is a relevant parameter in selecting therapy in HCC. The current clinical classification of HCC split patients into 5 stages, with a specific treatment schedule for any stage. As patients with early stages can receive curative treatments, such as surgical resection, liver transplantation or local ablation, surveillance program in high-risk populations has become mandatory. Sorafenib, a multikinase inhibitor, has recently shown survival benefits in patients at advanced stage of disease. Hopefully, new molecular targeted therapies and their combination with sorafenib or interventional and surgical procedures, should expand the therapeutic armamentarium against HCC.

    Metastatic basal cell carcinoma (MBCC) of the skin is rare in occurrence and may initially elude proper diagnosis and management. We describe a case of MBCC to cervical lymph nodes, originally evaluated and treated surgically as metastatic thyroid carcinoma. After definitive diagnosis of MBCC was made, chemotherapy and concomitant radiation treatment were initiated; however, despite these measures, the patient then developed MBCC to the lung. Risk factors and current therapeutic modalities for MBCC are also discussed. In addition to the more commonly metastasizing carcinomas, metastases from a cutaneous basal cell carcinoma primary tumor should be considered when evaluating cervical lymph node metastases of an uncertain head and neck primary.

    Full Text Available O carcinoma basocelular é a neoplasia maligna mais comum em humanos e sua incidência vem aumentando nas últimas décadas. Sua grande frequência gera significativo ônus ao sistema de saúde, configurando problema de saúde pública. Apesar das baixas taxas de mortalidade e de rara ocorrência de metástases, o tumor pode apresentar comportamento invasivo local e recidivas após o tratamento, provocando importante morbidade. Exposição à radiação ultravioleta representa o principal fator de risco ambiental associado a sua gênese. Entretanto, descrevem-se outros elementos de risco: fotótipos claros, idade avançada, história familiar de carcinomas de pele, olhos e cabelos claros, sardas na infância e imunossupressão, além de aspectos comportamentais, como exercício profissional exposto ao sol, atividade rural e queimaduras solares na juventude. Entre 30% e 75% dos casos esporádicos estão associados à mutação do gene patched hedgehog, mas outras alterações genéticas são ainda descritas. A neoplasia é comumente encontrada concomitantemente com lesões cutâneas relacionadas à exposição solar crônica, tais como: queratoses actínicas, lentigos solares e telangiectasias faciais. A prevenção do carcinoma basocelular se baseia no conhecimento de fatores de risco, no diagnóstico e tratamento precoces e na adoção de medidas específicas, principalmente, nas populações susceptíveis.

    To determine the maximum tolerated dose (MTD) of cisplatin administered with piroxicam, the antitumor activity and toxicity of cisplatin combined with piroxicam in dogs with oral malignant melanoma (OMM) and oral squamous cell carcinoma (SCC), and the effects of piroxicam on the pharmacokinetics of cisplatin in dogs with tumors. Prospective nonrandomized clinical trial. 25 dogs. Dogs were treated with a combination of cisplatin (escalating dose with 6 hours of diuresis with saline [0.9% NaCI] solution) and piroxicam (0.3 mg/kg 10.14 mg/lb], PO, q 24 h). The initial cisplatin dose (50 mg/m2) was increased by 5 mg/m2 until the MTD was reached. Tumor stage and size were determined at 6-week intervals during treatment. The pharmacokinetics of cisplatin were determined in dogs receiving a combination of cisplatin and piroxicam during the clinical trial and dogs that were treated with cisplatin alone. 11 dogs with OMM and 9 dogs with SCC were included in the clinical trial. The MTD of cisplatin when administered in combination with piroxicam was 50 mg/m2. Tumor remission occurred in 5 of 9 dogs with SCC and 2 of 11 dogs with OMM. The most common abnormality observed was renal toxicosis. Clearance of cisplatin in dogs that were treated with cisplatin alone was not significantly different from that in dogs treated with a combination of cisplatin and piroxicam. Cisplatin administered in combination with piroxicam had antitumor activity against OMM and SCC. The level of toxicity was acceptable, although renal function must be monitored carefully.

Between December 2011 and December 2014, CT-guided RFA was performed in 31 patients with 31 biopsy-proven RCCs (median, 2.1 cm). RFA included planning, targeting, monitoring and survey phases. The dose length product (DLP), CT dose index volume (CTDIvol), effective dose, number of scans, scan range, tube current and exposure time of RFA phases were compared. The 3-year recurrence-free survival rate was recorded. Nonparametric or parametric repeated-measures ANOVA with Dunn's or Tukey-Kramer multiple comparisons and Kaplan-Meier analysis were used for statistical analysis. The median total DLP, CTDIvol and effective dose of CT-guided RFA procedures per session were 1238.8 mGy (range 517.4-3391.7 mGy), 259.7 mGy (10.7-67.9 mGy) and 18.6 mSv (7.8-50.9 mSv), respectively. The median DLP, CTDIvol, effective dose, number of scans, tube current and exposure time during the targeting phase were higher than those during the other phases (p  0.05) but smaller than those in the planning and survey phases (p guiding RFA may reduce radiation dose without compromising oncologic outcomes. Reducing the number of scans during the targeting phase contributes to dose reduction.

    Merkel cell carcinoma (MCC) is a rare and aggressive cutaneous neoplasm that has exhibited an exponential increase in incidence in the past 3 decades. Combined MCC and cutaneous squamous cell carcinoma (SCC/MCC) is an uncommon variant of MCC that exhibits worse prognosis than pure MCC. To describe the clinical presentation, dermoscopy, and histology of an unusual subtype of combined SCC/MCC. A 73-year-old white woman presented with an ulcerated and violaceous 10-mm plaque on her right jawline that had been present for 2 to 3 months. On dermoscopy, the lesion was predominantly milky pink to red with peripheral crusting and large-caliber polymorphous vessels. Histology revealed SCC in situ above and adjacent to MCC. The tumor was excised with clear margins, and sentinel lymph node scintography was negative for nodal involvement. © The Author(s) 2016.

    Full Text Available Abstract Introduction We report a case of pulmonary metastatic recurrence of renal adenocarcinoma soon after radical nephrectomy that was followed by renal transplant and immunosuppressive medication. Increased risk of metastatic recurrence of renal cell carcinoma should be considered in the immediate post-transplant period when immunosuppressive medication is administered, even if nephrectomy had been performed many years earlier. Case presentation In 1986 the patient demonstrated renal insufficiency secondary to mesangial glomerulonephritis. In 1992 he underwent left side radical nephrectomy with histopathological diagnosis of clear cell adenocarcinoma. Mesangial glomerulonephritis in the remaining right kidney progressed to end-stage renal failure. In October 2000 he received a kidney transplant from a cadaver and commenced immunosuppressive medication. Two months later, several nodules were found in his lungs, which were identified as metastases from the primary renal tumor that had been removed with the diseased kidney 8 years earlier. Conclusion Recurrence of renal cell carcinoma metastases points to tumor dormancy and reflects a misbalance between effective tumor immune surveillance and immune escape. This case demonstrates that a state of tumor dormancy can be interrupted soon after administration of immunosuppressant medication.

    Community-level socioeconomic status, particularly insurance status, is increasingly becoming important as a possible determinant in patient outcomes. To determine the association of insurance and community-level socioeconomic status with outcome for patients with pharyngeal squamous cell carcinoma (SCC). This study extracted data from more than 1500 Commission on Cancer-accredited facilities collected in the National Cancer Database. A total of 35 559 patients diagnosed with SCC of the pharynx from 2004 through 2013 were identified. The χ2 test, Kaplan-Meier method, and Cox regression models were used to analyze data from April 1, 2016, through April 16, 2017. Overall survival was defined as time to death from the date of diagnosis. Among the 35 559 patients identified (75.6% men and 24.4% women; median age, 61 years [range, 18-90 years]), 15 146 (42.6%) had Medicare coverage; 13 061 (36.7%), private insurance; 4881 (13.7%), Medicaid coverage; and 2471 (6.9%), no insurance. Uninsured patients and Medicaid recipients were more likely to be younger, black, or Hispanic; to have lower median household income and lower educational attainment; to present with higher TNM stages of disease; and to start primary treatment at a later time from diagnosis. Those with private insurance (reference group) had significantly better overall survival than uninsured patients (hazard ratio [HR], 1.72; 95% CI, 1.59-1.87), Medicaid recipients (HR, 1.99; 95% CI, 1.88-2.12), or Medicare recipients (HR, 2.07; 95% CI, 1.99-2.16), as did those with median household income of at least $63 000 (reference) vs $48 000 to $62 999 (HR, 1.19; 95% CI, 1.13-1.26), $38 000 to $47 999 (HR, 1.31; 95% CI, 1.24-1.38), and less than $38 000 (HR, 1.51; 95% CI, 1.43-1.59). On multivariable analysis, insurance status and median household income remained independent prognostic factors for overall survival even after accounting for educational attainment, race, Charlson/Deyo comorbidity

    IntroductionThe authors compared the oncologic outcomes of radiofrequency ablation (RFA) with robotic-assisted partial nephrectomy (RPN) for the treatment of T1 stage renal cell carcinoma (RCC).Materials and methodsThis was a retrospective data analysis of a high-volume single tertiary centre. Patients were treated with RFA or RPN following multidisciplinary decision making. Only histologically proven RCCs were included. Baseline demographics were collected, and PADUA scores of tumour features were calculated to standardize baseline anatomy. Peri-operative complications, kidney function and oncological outcomes were compared.ResultsSixty-three cases were included in each group. Baseline renal function was poorer in RFA, and 16/63 RFA patients had tumours in single kidneys compared to 1/63 RPN cases (p < 0.001). Length of stay was shorter in RFA (1 vs. 3 days, p < 0.0001). Post-procedure renal function decline at 30 days was significantly less in RFA [(−0.8) ± 9.6 vs. (−16.1) ± 19.5 mls/min/1.73 m{sup 2}; p < 0.0001]. More minor complications were recorded in RPN (10/63 vs. 4/63, p = 0.15), but local recurrence was numerically higher in RFA (6/63 vs. 1/63, p = 0.11). Disease-free survival (DFS) was not significantly different (adjusted HR = 0.6, 95 % Cl 0.1–3.7; p = 0.60). Increasing tumour size was an independent predictor of local recurrence (adjusted HR = 1.7; 95 % Cl 1.1–2.6 per cm; p = 0.02).ConclusionsBoth RPN and RFA offer very good oncological outcomes for the treatment of T1 RCC with low peri-operative morbidity and similar oncologic outcomes. RFA demonstrated fewer peri-operative complications and better preservation of renal function, whereas RPN had an insignificantly lower local recurrence rate. RFA should be offered alongside RPN for selected cases.

    Regulatory T cells (Treg) play an important role in the maintenance of immune tolerance and may be one of the obstacles of successful tumor immunotherapy. In this study, we analyzed the impact of administration of dendritic cell (DC) vaccination in combination with low-dose interleukin (IL)-2...... to an increase in the number of Treg cells whereas IL-21 does not stimulate the induction of Treg cells. These findings demonstrate that even low doses of IL-2 in combination with DC vaccination are able to expand CD4(+)CD25(+)Foxp3(+) Treg cells in vivo in metastatic renal cell carcinoma patients. Further......, the results indicate that the IL-2-induced effect on Treg cells is reversible and declines shortly after termination of IL-2 treatment. Our data suggest that approaches combining DC-mediated immunotherapy and depletion of Treg cells may be necessary to enhance the ability of vaccination therapy to elicit...

Here, we summarize an up-to-date review of the literature on genetics, diagnosis (ultrasound scan, fine needle aspiration, frozen section, etc., and management. At presentation, treatment decision should be made by a multidisciplinary board. Recurrent HCCs are seldom curable despite salvage treatments, which include radioactive iodine ablation, radiofrequency ablation, ethanol ablation, external radiotherapy, and systemic therapy. Further research is needed to develop more efficacious systemic treatments. Currently, lenvatinib, sunitinib, and sorafenib are available.

    Basal cell carcinoma (BCC) rarely metastasizes. However, this unfortunate outcome can occur, usually in neglected tumors. We report a 52-year-old man with a BCC on the left chest that enlarged and then ulcerated over a 6-year period. Metastasis of the tumor to lymph nodes in the left axilla resulted, but the patient remains free of disease 24 months after wide excision, lymph node dissection, and local radiation therapy to the axilla.

    Full Text Available Primary pancreatic small cell carcinoma (SCC is rare, with just over 30 cases reported in the literature. Only 7 of these patients underwent surgical resection with a median survival of 6 months. Prognosis of SCC is therefore considered to be poor, and the role of adjuvant therapy is uncertain. Here we report two institutions’ experience with resectable pancreatic SCC. Six patients with pancreatic SCC treated at the Johns Hopkins Hospital (4 patients and the Mayo Clinic (2 patients were identified from prospectively collected pancreatic cancer databases and re-reviewed by pathology. All six patients underwent a pancreaticoduodenectomy. Clinicopathologic data were analyzed, and the literature on pancreatic SCC was reviewed. Median age at diagnosis was 50 years (range 27-60. All six tumors arose in the head of the pancreas. Median tumor size was 3 cm, and all cases had positive lymph nodes except for one patient who only had five nodes sampled. There were no perioperative deaths and three patients had at least one postoperative complication. All six patients received adjuvant therapy, five of whom were given combined modality treatment with radiation, cisplatin, and etoposide. Median survival was 20 months with a range of 9-173 months. The patient who lived for 9 months received chemotherapy only, while the patient who lived for 173 months was given chemoradiation with cisplatin and etoposide and represents the longest reported survival time from pancreatic SCC to date. Pancreatic SCC is an extremely rare form of cancer with a poor prognosis. Patients in this surgical series showed favorable survival rates when compared to prior reports of both resected and unresectable SCC. Cisplatin and etoposide appears to be the preferred chemotherapy regimen, although its efficacy remains uncertain, as does the role of combined modality treatment with radiation.

Through this study, we understand that kidney disease over the years had higher incidence rates, especially in adults in the sixth decade of life. The renal cell carcinoma (RCC is the third most common malignancy of the genitourinary tract, affecting 2% to 3% of the population. There are numerous ways of diagnosis; however, the most important are ultrasonography, magnetic resonance imaging and computed tomography. In general most of the patients affected by the CCR, have a good prognosis when diagnosed early and subjected to an effective treatment. This study conducted a literature review about the CCR, through this it was possible to understand the development needs of the imaging methods used for precise diagnosis and classification of RCC through the TNM system.

    2017-03-01

    Full Text Available Small cell carcinoma of the vagina is rare, so rare in fact that the total number reported in English-language journals is less than 30. Due to this extremely low incidence, no specific treatment guidelines have been established, and most of what is clinically known is derived from a handful of single case reports. However, as befitting its highly aggressive histologic features, which are reminiscent of small cell lung cancer (SCLC, first-line treatment is modeled after SCLC. Herein is reported the case of a 51-year-old African-American patient with metastatic biopsy-proven small cell carcinoma of the vagina that progressed through multiple therapies: first-line cisplatin and etoposide (making it platinum-resistant and radiotherapy, followed by the tumor macrophage-stimulating agent RRx-001 in a clinical trial called QUADRUPLE THREAT, which per protocol preceded a mandated rechallenge with cisplatin and etoposide. RECIST v.1.1 tumor progression on both RRx-001 and cisplatin/etoposide was accompanied by central necrosis in several of the enlarged lymph nodes and hepatic metastases, which may have been evidence of pseudoprogression, accounting for her ongoing longer-than-expected survival, since the necrotic tissue may have primed the activity of the PD-1 inhibitor. The lack of response to RRx-001 is hypothesized to have correlated with sparse tumor macrophage infiltration, seen on pre- and post-treatment biopsies, since the mechanism of action of RRx-001 relates to stimulation of tumor-associated macrophages.

    1987-06-01

    One hundred and one patients with nasopharyngeal squamous cell carcinoma (NPC) were treated with irradiation. The UICC TNM staging system (1978) was applied : 6 patients were T1NO, 10 T2NO, 5 T3NO, 13 T4NO, 11 T1N+, 18 T2N+, 19 T3N+ and 19 T4N+. Since 1978, computed tomography (CT) was available, and 34 patients were examined with CT at first presentation. The technique of radiotherapy was markedly changed around 1978. The field to the primary site and neck were enlarged. Two-year relapse-free survival was significantly better for the post-CT era than pre-CT era. This was mainly due to improved local-recurrence-free survival and cervical-relapse-free survival. Improvement of local-recurrence-free survival, however, was appreciated in only T3 + T4 patients, there were no differences in T1 + T2 patients. This failure to increase local-recurrence-free survival in the T1 + T2 patients may relate to the fact that a large number of these patients showed T3 or T4 tumors on CT. In 34 patients with CT examination, 14 patients were upstaged based on CT findings alone. Since many clinical T1 or T2 tumors determined without CT information were upstaged to T3 or T4 after performing CT, we studied treatment results of them according to CT staging. Nine of 16 clinical T1 + T2 tumors upstaged to T3 or T4 after performing CT, 3 of which had local recurrence. Seven patients remained as T1 + T2 after performing CT, only one of which experienced local recurrence. It is suggested that mere enlarging of radiation fields or increasing radiation doses could not be curative for a certain group of patients. In order to further increase local control rates, we have started to use intracavitary irradiation with an after-loading technique as a boost. No acute or chronic complications due to intracavitary irradiation have developed. Preliminary results were encouraging.

    Full Text Available Lung cancer is one of the most common malignant tumors. As over 70 % of patients at diagnosis have locally advanced or generalized process, the majority of patients receive drug treatment only. We evaluated effectiveness and toxicity of pemetrexed (Alimta in 24 patients with locally advanced and metastatic non-squamous cell non-small-cell lung carcinoma with the known EGFR mutation status. Pemetrexed 500 mg/m2 was administered as monotherapy (8 patients or in combination with platinum-based drugs (15 patients. Three (12.5 % patients showed complete regression, 7 (29.2 % – partial regression, 10 (41.7 % – stabilization, 4 (16.6 % – progression. The median survival was 14.8 months. Non-hematological complications were registered, usually concerning the digestive system. Hematological complications included first-degree leukopenia – 27 (21.3 %, second- and third-degree thrombocytopenia – 1 case of each (0.8%. The complications did not require administration of drugs or were corrected medicamentally. We observed a high effectiveness of pemetrexed in patients with non-squamous NSCLC, as well as a low rate of complications and controlled toxicity.

O tratamento consiste de radio e/ou quimioterapia, eventualmente seguidos pela ressecção do tumor. O objetivo é avaliar o seguimento desses doentes para verificar as recidivas e a evolução do NIAA para câncer. Apresentação da casuística da Equipe Técnica de Proctologia do Instituto de Infectologia Emílio Ribas, de São Paulo. MÉTODOS: Acompanhamos 45 doentes HIV-positivos portadores de carcinoma espinocelular anal e seu precursor no período de 1996 a 2006. Eram 30 neoplasias intra-epiteliais anais de alto grau (NIAA, tratadas com ressecção local e 15 carcinomas invasores do canal anal. Nove das 15 lesões invasivas foram submetidas ao esquema de Nigro isolado ou associado à ressecção local, amputação abdominoperineal ou colostomia para derivação. RESULTADOS: No seguimento ambulatorial das NIAA tivemos recidiva em 16,7% e não observamos evolução para carcinoma, num período mínimo de três anos. Entre os nove tumores submetidos ao esquema de Nigro, com ou sem operação complementar, cinco estão livres de tumor. Nenhum tratamento foi feito em cinco doentes. Em três, devido às péssimas condições clínicas, e em dois, pois recusaram tratamento. Outro teve diagnóstico na vigência de oclusão intestinal sendo submetido à colostomia de derivação. CONCLUSÃO: Concluímos que a NIAA pode reincidir após excisão local em doentes HIV-positivos, mas não evolui para carcinoma invasor e que os doentes de câncer anal invasor podem ser tratados da mesma maneira que a população soronegativa para o HIV desde que as condições clínicas o permitam.OBJECTIVE: Incidence of anal squamous cell carcinoma is increasing mainly among HIV-positive patients.

    Purpose Surgical management of upper tract urothelial carcinoma requires removal of kidney and ureter, compromising renal function. Non-surgical alternatives have potentially prohibitive safety concerns. We examine the feasibility and safety of ablation of the ureter and renal pelvis using endoluminal vascular-targeted photodynamic therapy in a porcine model and report efficacy of WST11 vascular-targeted photodynamic therapy in a murine model. Materials and Methods Following approval, we performed 28 endoluminal ablations in the ureters and renal pelvis of 18 swine. Intravenous infusion of WST11 (4mg/kg) followed by laser illumination (10 minutes) was performed via percutaneous access or retrograde ureteroscopic approach. Animals were followed clinically with laboratory testing, imaging and histology was evaluated at several post-ablation time points. A murine xenograft was created with the 5637 human urothelial cell carcinoma line to determine sensitivity to this therapy. Results At 24 hours, 50 mW/cm laser fluence produced superficial necrosis of the ureter and deeper necrosis (penetrating the muscularis propria or adventitia) was produced by treatment with 200 mW/cm in the ureter and renal pelvis. At 4 weeks, superficial urothelium had regenerated over the treatment site. No symptomatic obstruction, clinically relevant hydronephrosis, or abnormality of lab testing was noted up to 4 weeks. In mice, 80% had no evidence of tumor at 19 days after WST11 vascular-targeted photodynamic therapy. Conclusions Urothelial cell carcinoma appears to be sensitive to WST11 vascular-targeted photodynamic therapy. Depth of WST11 vascular-targeted photodynamic therapy treatment effects can be modulated in a dose-dependent manner by titration of light intensity. Moreover, this treatment modality, applied to the porcine upper urinary tract, is feasible via antegrade and retrograde access. PMID:26860792

In addition to this selective chemotherapy, we administered oral tegafur, which achieved complete remission of the tumor. These findings suggest that intra-arterial administration of peplomycin with tegafur is one of the optimal therapies for the treatment of SCC developing on the ear.

    We reported two cases of basal cell carcinoma (BCC) that developed after radiation therapy. A 50-year-old woman, who had received an unknown amount of radiation therapy for the treatment of intracranial germinoma at the age of 22, presented with several tumors around the radiation ulcer. All tumors showed BCC. A 33-year-old woman, who had received an unknown amount of radiation therapy on the head for the treatment of leukemia at the age of 2, presented with a black nodule within the area of irradiation. The tumor showed BCC. We discuss the occurrence of BCC after radiation therapy. (author)

    Red dot basal cell carcinoma is a unique variant of basal cell carcinoma. Including the three patients described in this report, red dot basal cell carcinoma has only been described in seven individuals. This paper describes the features of two males and one female with red dot basal cell carcinoma and reviews the characteristics of other patients with this clinical subtype of basal cell carcinoma. A 70-year-old male developed a pearly-colored papule with a red dot in the center on his nasal tip. A 71-year-old male developed a red dot surrounded by a flesh-colored papule on his left nostril. Lastly, a 74-year-old female developed a red dot within an area of erythema on her left mid back. Biopsy of the lesions all showed nodular and/or superficial basal cell carcinoma. Correlation of the clinical presentation and pathology established the diagnosis of red dot basal cell carcinoma. The tumors were treated by excision using the Mohs surgical technique. Pubmed was searched with the keyword: basal, cell, cancer, carcinoma, dot, red, and skin. The papers generated by the search and their references were reviewed. Red dot basal cell carcinoma has been described in three females and two males; the gender was not reported in two patients. The tumor was located on the nose (five patients), back (one patient) and thigh (one patient). Cancer presented as a solitary small red macule or papule; often, the carcinoma was surrounded by erythema or a flesh-colored papule. Although basal cell carcinomas usually do not blanch after a glass microscope slide is pressed against them, the red dot basal cell carcinoma blanched after diascopy in two of the patients, resulting in a delay of diagnosis in one of these individuals. Dermoscopy may be a useful non-invasive modality for evaluating skin lesions when the diagnosis of red dot basal cell carcinoma is considered. Mohs surgery is the treatment of choice; in some of the patients, the ratio of the area of the postoperative wound to that

    We studied the effect of the combined therapy with interleukin-2 (IL-2) and radiation on renal cell carcinoma using an in vivo like growing culture system. We tested renal cell carcinoma obtained at surgery. After tumors were sliced into 2-mm square specimens, they were placed on a collagen gel-matrix filled with medium, and cultured for 7 days. 5 and 10 Gy were irradiated 3 days after the beginning of cell cultures. We also tested 100 JRU/ml of IL-2 added to each culture medium. The killing activity of each treatment was measured by the rate of 3 H-thymidine uptake. In the 5 Gy groups (n=9), we observed a significant effect in one treated with radiation alone (11.1%) and in 4 treated with the combined therapy (44.4%). Of these 4 having a significant effect with the combined therapy, one also had it with either radiation alone or combined therapy. The combined therapy was significantly effective compared with radiation alone. One had a significant effect with the combined therapy, and the remaining 2 had a significant effect by either combined therapy or radiation alone. In the 10 Gy group (n=12), a significant effect was seen in one with IL-2 treatment alone (8.3%), one with radiation alone (8.3%), and 4 with the combined therapy (33.3%). Of these 4 cases having a significant effects with the combined therapy, one had it by either radiation alone or the combined therapy, and the combined therapy was more effective than radiation alone. Two cases had a significant effect by the combined therapy, and the remaining one had it by either the combined therapy or radiation alone. We conclude that the combined therapy with IL-2 and radiation is effective for renal carcinoma, especially in the group irradiated with 5 Gy. (J.P.N.)

    Both small cell carcinoma and sarcomatoid carcinoma of the urinary bladder are highly aggressive tumors, and a concurrence of these tumors is extremely rare. We report a case of urinary bladder cancer with small cell carcinoma as a predominant component, accompanied by sarcomatoid carcinoma and conventional urothelial carcinoma (UC). Although the small cell carcinoma component had resolved on receiving chemoradiotherapy, rapid growth of the residual tumor led to a fatal outcome. A 47-year-old man presented with occasional bladder irritation and had a 2-year history of asymptomatic hematuria. Cystoscopy revealed a huge mass in the urinary bladder, and transurethral resection was performed. Microscopically, small cell carcinoma was detected as the major tumor component. Spindle-shaped sarcomatoid cells were also observed that were intermingled with small cell carcinoma and conventional UC. In addition, a sheet-like growth of the lipoblast-like neoplastic cells was observed focally. Initially, by providing chemoradiotherapy, we achieved a marked tumor regression; however, the tumor rapidly regrew after the completion of chemoradiotherapy, and the patient underwent radical cystectomy. Only conventional UC and sarcomatoid carcinoma were identified in the cystectomy specimen. The patient died of the disease 4 months after cystectomy. Urinary bladder cancer may include a combination of multiple aggressive histologies as in the present case. Because the variation in the tumor components may affect the efficacy of therapy, a correct diagnosis of every tumor component is necessary. Copyright © 2016 Elsevier GmbH. All rights reserved.

    Patients with advanced basal cell carcinoma have limited treatment options. Hedgehog pathway signalling is aberrantly activated in around 95% of tumours. We assessed the antitumour activity of sonidegib, a Hedgehog signalling inhibitor, in patients with advanced basal cell carcinoma. BOLT is an ongoing multicentre, randomised, double-blind, phase 2 trial. Eligible patients had locally advanced basal cell carcinoma not amenable to curative surgery or radiation or metastatic basal cell carcinoma. Patients were randomised via an automated system in a 1:2 ratio to receive 200 mg or 800 mg oral sonidegib daily, stratified by disease, histological subtype, and geographical region. The primary endpoint was the proportion of patients who achieved an objective response, assessed in the primary efficacy analysis population (patients with fully assessable locally advanced disease and all those with metastatic disease) with data collected up to 6 months after randomisation of the last patient. This trial is registered with ClinicalTrials.gov, number NCT01327053. Between July 20, 2011, and Jan 10, 2013, we enrolled 230 patients, 79 in the 200 mg sonidegib group, and 151 in the 800 mg sonidegib group. Median follow-up was 13·9 months (IQR 10·1-17·3). In the primary efficacy analysis population, 20 (36%, 95% CI 24-50) of 55 patients receiving 200 mg sonidegib and 39 (34%, 25-43) of 116 receiving 800 mg sonidegib achieved an objective response. In the 200 mg sonidegib group, 18 (43%, 95% CI 28-59) patients who achieved an objective response, as assessed by central review, were noted among the 42 with locally advanced basal cell carcinoma and two (15%, 2-45) among the 13 with metastatic disease. In the 800 mg group, 35 (38%, 95% CI 28-48) of 93 patients with locally advanced disease had an objective response, as assessed by central review, as did four (17%, 5-39) of 23 with metastatic disease. Fewer adverse events leading to dose interruptions or reductions (25 [32%] of 79

    Squamous cell carcinoma ofthe anal canal represents 1.5% of all malignancies affectingthe gastrointestinal tract. Over the past 20 years dramatic changes have been seen in both the epidemiological distribution of the disease and in the therapeutic modalities utilised to manage it. CLINICAL MANAGEMENT: Historically abdominoperineal resection had been the treatment of choice with local resection reserved for early stage disease. Work by Nigro et al. has revolutionised how we currently manage carcinoma of the anal canal, demonstrating combined modality chemoradiotherapy as an appropriate alternative to surgical resection with the benefit of preserving sphincter function. Surgery is then reserved for recurrent disease with salvage abdominoperineal resection. This article reviews current literature and highlights the changing therapeutic modalities with selected clinical cases

    Purpose: To investigate the significance of CD44 protein expression on the treatment outcomes of radiation therapy in patients with oropharyngeal squamous cell carcinoma (OPSCC) with or without p16 protein expression in the tumor tissue. Methods and Materials: We reviewed the medical records of 58 OPSCC patients who had undergone radiation therapy and examined the tumor tissue expressions of CD44 and p16 protein by immunohistochemical staining. The correlations between the expressions of these proteins and the patients' treatment outcomes were analyzed. Results: The data of 58 consecutive OPSCC patients who had undergone definitive intensity modulated radiation therapy were analyzed. The male/female ratio was 55:3, and the median age was 64 years. The clinical stage of the disease was stage II in 7 patients, stage III in 5 patients, stage IVA in 35 patients, and stage IVB in 11 patients. Of the patients, 79% received additional induction and/or concurrent chemotherapy. The median follow-up duration was 34 months. The 3-year overall survival, progression-free survival (PFS) and locoregional control (LRC) rates of all the patients, regardless of the results of immunohistochemistry, were 73%, 64% and 76%, respectively. The PFS and LRC rates in the CD44{sup −} patients (86% and 93%, respectively) were significantly higher than those in the CD44{sup +} patients (57% and 70%, respectively). The PFS and LRC rates in the p16{sup +} patients (83% and 90%, respectively) were significantly higher than those in the p16{sup −} patients (45% and 61%, respectively). Patients who were CD44{sup −}/p16{sup +} showed the best LRC rates, and those who were CD44{sup +}/p16{sup −} showed the worst PFS and LRC rates among all the groups. Conclusions: Profiling of CD44 and p16 protein expressions by immunohistochemical staining is useful for predicting the treatment outcomes in patients with OPSCC undergoing definitive intensity modulated radiation therapy.

    Neuroendocrine small cell carcinoma of the uterine cervix (SCC) is a rare disease that mixes clinical and biological characteristics of both cervical neoplasms and neuroendocrine small cell cancer. The prognosis is poor and the optimal treatment has not yet been clarified. Multimodality treatment, with surgery and concurrent chemoradiation has recently been shown to improve local control and survival rates.

    A selected group of 136 patients with Stage I squamous cell carcinoma of the cervix was treated in six naval hospitals during the period 1957--1965 using a three-stage combined radiation therapy and surgery protocol. Treatment consisted of two radium applications to the cervix, followed in 6 weeks by extraperitoneal lymphadenectomy. If the lymph nodes were tumor-negative, simple hysterectomy in 3 to 6 months completed the protocol. If the nodes were tumor-positive, a course of external pelvic irradiation was given with midline shielding. The incidence of positive nodes was 9.6 percent. Actuarial survival for all patients was 89.4 percent, comparable to the rate obtained by radical surgery or radiation alone. Postoperative and postradiation complications were minimal, with no urinary or bowel fistulas. There was no operative mortality

    Ultrasonography of the upper abdomen disclosed an oval well defined mass in the pancreas. Round cell anaplastic carcinoma is one of sarcomatoid pancreatic carcinoma, microscopically characterized by monotonous sheaths of small round plump cells with rare giant cells and thus more or less reminiscent of malignant lymphoma. Whether this tumor is of ductal or acinar cell origin remains to be determined. Clinically, this tumor does not differ significantly from ordinary adenocarcinoma of the pancreas. We report a cases of round cell anaplastic carcinoma and describe the CT and sonographic findings, and discuss the differential points from other solid pancreatic tumors.

    Differentiated thyroid carcinoma includes 2 different tumor types, papillary (PC) and follicular carcinoma (FC), and although similar, their prognosis is different. FC is uncommon, and this has led to it often being analyzed together with PC, and therefore the true reality of this tumor is difficult to know. As a result, the diagnostic and therapeutic management and the prognostic factors in differentiated carcinoma are more predictive of PC than FC. In this review we analyze the current state of many of the therapeutic aspects of this pathology. The best surgical technique and the usefulness of associated lymphadenectomy is also analyzed. Regarding post-surgical ablation with 131I, the indications, doses and usefulness are discussed. For the remaining therapies we analyze the few indications for radiotherapy and chemotherapy, and of new drugs such as tyrosine kinase inhibitors. Copyright © 2015 AEC.

    Full Text Available Oral carcinoma is one of the most prevalent cancers and one of the 10th most common causes of death worldwide. Oral squamous cell carcinoma accounts for nearly 90% of all oral carcinomas. Squamous cell carcinoma is the malignant neoplasm of mucosal origin. The etiology of squamous cell carcinoma is multifactorial. The use of tobacco and betel quid, heavy alcohol drinking, intake of diet low in fresh fruits and vegetables, viruses, trauma, and genetics are considered as possible risk factors. Early diagnosis of oral squamous cell carcinoma plays an important role in improving prognosis and reducing morbidity and mortality associated with it. It can be managed by surgery, chemotherapy, radiotherapy, or combination of all these, but regardless of its treatment modality, the 5-year survival rate is poor at about 50%. This case report demonstrates a case of oral squamous cell carcinoma induced by Chewstick trauma with a history of no deleterious habits and is confirmed by clinical and histopathological examination.

    A proposed origin of acinous cell carcinoma of the parotid gland from serous cells of the acinar part of the salivary unit has been challenged. To date, the alternative histogenetic concept of origin from the reserve cell of the intercalated duct has been largely conjectural and based on light microscopic and only isolated electron microscopic evidence. Light and electron microscopic findings now support a terminal duct origin for at least some acinous cell carcinomas.

    The horseshoe kidney is one of the most common congenital disorders affecting the urogenital system. Following a fusion of the lower kidney poles, which in turn lead to the formation of an isthmus, this anatomical variation is accompanied by other characteristic properties like an incomplete ascension, ventral rotation of the pelvices as well as atypical vascular supply. Even though renal carcinoids and Wilms tumors are more common in horseshoe kidneys, the incidence of renal cell carcinomas seems to be unaffected. Here we report the case of a locally advanced renal cell carcinoma with extensive venous invasion occurring in a horseshoe kidney and its complex surgical management. The whole primary tumor as well as a majority of venous tumor thrombi could be removed by a combination of 2/3 nephrectomy and cavotomy with thrombectomy. During 1 year of follow-up, the patient neither suffered from a tumor relapse, nor did he require renal replacement therapy. Thus, we conclude that even in cases of RCC where advanced disease is associated with complex anatomical situations, organ-preserving surgical treatment should be pursued to achieve excellent functional and oncological results. © 2016 S.

    The aim of this study was to assess the efficacy and safety of a combination regimen of capecitabine plus cisplatin (CC) or capecitabine plus paclitaxel (CP) as a first-line treatment in patients with metastatic esophageal squamous cell carcinoma. Patients with recurrent or metastatic esophageal squamous cell carcinoma were enrolled in this open-label, phase II, randomized trial. Patients were assigned to either the CC arm (days [D]1–14 capecitabine 1000 mg/m 2 twice daily + D1 cisplatin 75 mg/m 2 , every 3 weeks) or the CP arm (D1–14 capecitabine 1000 mg/m 2 twice daily + D1, 8 paclitaxel 80 mg/m 2 , every 3 weeks). The primary endpoint of the study was response rate and secondary endpoints were progression-free survival (PFS), overall survival (OS), toxicity and quality of life. A total of 94 patients were entered into this study between October 2008 and October 2012, 46 patients in the CC arm and 48 in the CP arm. Patients in both arms received a median of six cycles of treatment (range, 1–14) and the response rates were 57 and 58 % in the cisplatin and paclitaxel arm, respectively. With a median follow-up of 23 months, the median PFS was 5.1 months (95 % CI 4.0–6.2 months) in the cisplatin arm and 6.7 months (95 % CI 4.9–8.5 months) in the paclitaxel arm, whereas the median OS was 10.5 months (95 % CI 9.2–11.9 months) in the cisplatin arm and 13.2 months (95 % CI 9.4–17.0 months) in the paclitaxel arm. Patients in the cisplatin arm were more likely to experience neutropenia and thrombocytopenia, whereas patients in the paclitaxel arm had a higher frequency of neuropathy and alopecia. Quality of life was similar between treatment arms. Both CC and CP regimens were effective and well tolerated as a first-line treatment in patients with metastatic esophageal squamous cell carcinoma

Induction of apoptosis in cancer cells has been monitored during the cells' progression to apoptosis by anti-cancer drugs and inhibitors of the cell surface glycolipids, gangliosides and SA-Le(x) biosyntheses [Basu, S (1991) Glycobiology, 1, 469-475; and ibid, 427-435] in animal tissues and human carcinoma cells, respectively. Induction of apoptosis in cancer cells by cell surface glycolipids in the human breast cancer (SKBR3) cells is the aim in this study. We have employed the disialosyl gangliosides (GD3 and GD1b) to initiate apoptosis in SKBR3 cells grown in culture in the presence of (14)C-L-Serine. At lower concentrations (0-20 microM) of exogenously added non-radioactive GD3, GD1b, or bovine ganglioside mixture (GM1:GD1a:GD1b:GT1a 2:4:4:2), the incorporation of radioactivity in both (14)C-sphingolipid and (14)C-ceramide was higher. However, at higher concentrations (20-100 microM), wherein apoptosis occurred in high frequency, the (14)C-incorporation decreased in both GSLs and ceramide. Apoptosis induction was monitored by the concomitant appearance of caspase-3 activation and the binding of a fluorescent dye PSS-380 to the outer leaflet of phosphatidyl-serine. These results indicated that, in addition to many unknown cell surface glycoconjugates GD3 or GD1b (disialosyl ganglioside) could play an important role in the regulation of breast carcinoma cell death.

    Ovarian clear cell carcinoma (OCCC) is a worst histological subtype than other ovarian malignant tumor. Heparin-binding epidermal growth factor-like growth factor (HB-EGF) is a promising target for ovarian cancer therapy. The aims of this study were to validate the efficacy of HB-EGF–targeted therapy for OCCC and to identify the transcription factor that contributed to the induction of HB-EGF by SN38 treatment in OCCC cells. HB-EGF was highly expressed in OCCC cells, and an increase of HB-EGF was induced by SN38 which had only antitumor effect among conventional anticancer agents on OCCC. A specific inhibitor of HB-EGF, a cross-reacting material 197 (CRM197), led to a synergistic increase in the number of apoptotic OCCC cells with the treatment of SN38. The luciferase assay with 5′-deletion promoter constructs identified a GC-rich element between −125 and −178 (the distal transcription start site was denoted +1) as a cis-regulatory region, and the treatment of SN38 induced luciferase activity in this region. An in silico and chromatin immunoprecipitation analysis estimated that SP1 bound to the cis-regulatory region of HB-EGF in OCCC cells. Real-time PCR and cell viability assays showed that the transfection of a small interfering RNA targeting SP1 suppressed the expression of HB-EGF induced by SN38, resulting in the enhanced sensitivity of SN38. Taken together, these results indicate that induction of HB-EGF expression contributed to defense mechanism against treatment of SN38 through the transcriptional activity of SP1 in OCCC cells

    Full Text Available BACKGROUND: This study was performed to evaluate the safety and efficacy of paclitaxel with cisplatin as salvage therapy in patients previously treated with gemcitabine and cisplatin (G/C for advanced transitional cell carcinoma (TCC of the urothelial tract. METHODS: Twenty-eight patients with metastatic or locally advanced TCC who had received prior G/C chemotherapy were enrolled. All patients received paclitaxel (175 mg/m2 and cisplatin (60 mg/m2 every 3 weeks for eight cycles or until disease progression. RESULTS: The median age was 61 years (range, 43–83 years, and the median Eastern Cooperative Oncology Group performance status was 1 (range, 0–2. The overall response rate was 36% [95% confidence interval (95% CI = 18–54], with three complete responses and seven partial responses. The median time to progression was 6.2 months (95% CI = 3.9–8.5, and the median overall survival was 10.3 months (95% CI = 6.1–14.1. The most common Grade 3/4 nonhematologic and hematologic toxicities were emesis (10 of 28 patients; 36% and neutropenia (5 of 110 cycles; 5%. CONCLUSIONS: Salvage chemotherapy with paclitaxel and cisplatin displayed promising results with tolerable toxicity profiles in patients with metastatic or locally advanced TCC who had been pretreated with G/C.

    Full Text Available A twenty-year-old female saddle horse was referred for evaluation of a seven month, non-healing erosive lesion of the right hind hoof with proliferation and bleeding of the underlying soft tissues. This lesion had been twice surgically treated as a canker but rapidly recurred. Histological examination of the second excision revealed a well-differentiated squamous cell carcinoma. At presentation, the horse was mildly depressed, lame and partially non-weight-bearing on the right hind leg, which exhibited a 10 x 10 cm erosive and proliferative lesion remodeling the hoof. After completing staging procedures, the lesion was approached with surgery and intraoperative electrochemotherapy (ECT administration of bleomycin in isolated limb perfusion. A second session of surgery and ECT was performed one month later, followed by three additional monthly sessions of ECT. During periodic recheck, the mare showed continuous improvement. One year after presentation, the mare was in complete remission and her gait markedly improved. ECT was well-tolerated and resulted in improved local control of a tumor in a challenging anatomical district.

    Oral squamous cell carcinoma (OSCC) is often surrounded by epithelial dysplasia; leaving it unresected can result in local recurrence. Staining with Lugol's iodine solution detects epithelial dysplasia in oral mucosa, but whether it decreases local recurrence after OSCC surgery is unknown. This study investigated local recurrence rates in patients with early tongue cancer who underwent surgery using Lugol's staining. 93 patients with T1-2N0 tongue SCC underwent partial glossectomy using Lugol's staining during surgery. Resection was performed at least 5mm from the margin of the unstained area. Patients were investigated retrospectively for local recurrence status. Postoperative histology revealed negative surgical margins for SCC or epithelial dysplasia in 81 patients, close margins for SCC in 5, positive margins for mild epithelial dysplasia in 6, and a positive margin for SCC in one. Those with a positive or a close margin for SCC underwent additional resection 2-4 weeks after surgery; one was proved histologically to have residual SCC. No patients developed local recurrence, but 2 died of neck metastasis and 2 of distant metastasis. The 5-year disease specific survival rate was 93.8%. Lugol's staining during surgery can reduce local recurrence and improve survival in patients with early tongue SCC. Copyright © 2011 International Association of Oral and Maxillofacial Surgeons.

    2016-06-01

    Nevoid basal cell carcinoma syndrome, or basal cell nevus syndrome (Gorlin syndrome), is a rare autosomal dominantly inherited disorder that is characterized by development of basal cell carcinomas from a young age. Other distinguishing clinical features are seen in a majority of patients, and include keratocystic odontogenic tumors (formerly odontogenic keratocysts) as well as dyskeratotic palmar and plantar pitting. A range of skeletal and other developmental abnormalities are also often seen. The disorder is caused by defects in hedgehog signaling which result in constitutive pathway activity and tumor cell proliferation. As sporadic basal cell carcinomas also commonly harbor hedgehog pathway aberrations, therapeutic agents targeting key signaling constituents have been developed and tested against advanced sporadically occurring tumors or syndromic disease, leading in 2013 to FDA approval of the first hedgehog pathway-targeted small molecule, vismodegib. The elucidation of the molecular pathogenesis of nevoid basal cell carcinoma syndrome has resulted in further understanding of the most common human malignancy.

    Current treatment options for hepatocellular carcinoma (HCC) are often limited by the presence of underlying liver disease. In patients with liver cirrhosis, surgery, chemotherapy, and radiation therapy all carry a high risk of hepatic complications, ranging from ascites to fulminant liver failure. For patients receiving radiation therapy, cirrhosis dramatically reduces the already limited radiation tolerance of the liver and represents the most important clinical risk factor for the development of radiation-induced liver disease. Although improvements in conformal radiation delivery techniques have improved our ability to safely irradiate confined areas of the liver to increasingly higher doses with excellent local disease control, patients with moderate-to-severe liver cirrhosis continue to face a shortage of treatment options for HCC. In recent years, evidence has emerged supporting the use of bone marrow–derived stromal cells (BMSCs) as a promising treatment for liver cirrhosis, with several clinical studies demonstrating sustained improvement in clinical parameters of liver function after autologous BMSC infusion. Three predominant populations of BMSCs, namely hematopoietic stem cells, mesenchymal stem cells, and endothelial progenitor cells, seem to have therapeutic potential in liver injury and cirrhosis. Preclinical studies of BMSC transplantation have identified a range of mechanisms through which these cells mediate their therapeutic effects, including hepatocyte transdifferentiation and fusion, paracrine stimulation of hepatocyte proliferation, inhibition of activated hepatic stellate cells, enhancement of fibrolytic matrix metalloproteinase activity, and neovascularization of regenerating liver. By bolstering liver function in patients with underlying Child's B or C cirrhosis, autologous BMSC infusion holds great promise as a therapy to improve the safety, efficacy, and utility of surgery, chemotherapy, and hepatic radiation therapy in the

    2013-01-01

    Full Text Available Small cell carcinoma of the bladder is a rare, aggressive, poorly differentiated neuroendocrine neoplasm accounting for only 0.3-0.7% of all bladder tumors. Since the tumor is very rare, pathogenesis is uncertain. Small cell carcinomas of the urinary bladder are mixed with classic urothelial carcinomas or adenocarcinomas of the bladder in 68% cases, making pure primary small cell carcinoma even a rarer entity. The unknown etiology and natural history of small cell carcinoma of the urinary bladder represent a challenge both to the pathologist and urologists for its diagnosis and treatment, respectively.

    Abstract Merkel cell carcinoma (MCC) is a rare, aggressive, skin cancer of obscure histogenesis, the incidence of which is rising. There is no consensus on the optimal treatment. Our aim was to evaluate the staging, investigation, treatment, and follow-up of MCC in eastern Denmark......, and to investigate the incidence. We suggest guidelines for treatment. First we reviewed the medical records of 51 patients diagnosed with MCC from 1995 until 2006 in eastern Denmark. The nation-wide incidence of MCC was extracted from the Danish Cancer Registry for the calculations for the period 1986-2003. We...... reviwed published papers about MCC based on a MEDLINE search. Fourteen of the 51 patients developed recurrence, and 37 (73%) died during the study period. Mean follow-up was 13 months (range 1-122). A total of 153 patients were identified in the Danish Cancer Registry, and showed that incidence rates had...

    Sunitinib is an oral, multitargeted tyrosine kinase inhibitor that has been approved for the treatment of metastatic renal cell carcinoma. Although the majority of sunitinib-treated patients receive a clinical benefit, almost a third of the patients will not respond. Currently there is no available marker that can predict for response in these patients. We estimated the plasma levels of NT-pro-BNP (the N-terminal precursor of brain natriuretic peptide) in 36 patients that were treated with sunitinib for metastatic clear-cell renal carcinoma. From the 36 patients, 9 had progressive disease and 27 obtained a clinical benefit (objective response or disease stabilization). Increases in plasma NT-pro-BNP were strongly correlated to clinical outcome. Patients with disease progression increased plasma BNP at statistically significant higher levels than patients that obtained a clinical benefit, and this was evident from the first 15 days of treatment (a three-fold increase in patients with progressive disease compared to stable NT-pro-BNP levels in patients with clinical benefit, p < 0.0001). Median progression-free survival was 12.0 months in patients with less than 1.5 fold increases (n = 22) and 3.9 months in patients with more than 1.5 fold increases in plasma NT-pro-BNP (n = 13) (log-rank test, p = 0.001). This is the first time that a potential 'surrogate marker' has been reported with such a clear correlation to clinical benefit at an early time of treatment. Due to the relative small number of accessed patients, this observation needs to be further addressed on larger cohorts. More analyses, including multivariate analyses are needed before such an observation can be used in clinical practice

    The current preferred treatment of ovarian cancer is combination chemotherapy, usually a platinum-based drug coupled with paclitaxel (PTX). Here, we investigated whether co-treatment with valproic acid (VPA) could increase the efficiency of various ovarian cancer drugs-PTX, doxorubicin (DOX), carboplatin (CBP), and cyclophosphamide (CP)-in different ovarian cancer cell lines. Three different ovarian cancer cell lines (OVCAR-3, TOV-21G, and TOV-112D) were treated with chemotherapeutic drugs, alone or in combination with VPA. Cell viability (XTT assay), caspase-3 activity, and the expression of cell cycle- and apoptosis-related genes and proteins were assessed. Furthermore, the effects of these drugs on α-tubulin acetylation and DNA fragmentation were investigated. Paclitaxel and DOX decreased cell viability and increased caspase-3 activity, and co-treatment with VPA enhanced this effect. Carboplatin and CP had no effect. Responses to treatment with PAX and DOX together with VPA on gene expression profile were highly variable and depended on the cell line investigated. However, a common feature in all cell lines was an increased expression of CDKN1A, CCNE1, PARP1, and PARP3. Co-treatment with VPA enhanced the effect of DOX and PAX on most protein expressions investigated in TOV-21G and TOV-112D cell lines, whereas in OVCAR-3, the most effect was seen with DOX with VPA. Valproic acid did not increase PTX-induced α-tubulin acetylation. An additive effect of DOX with VPA on DNA fragmentation was observed in TOV-21G and TOV-112D cell lines but not in the OVCAR-3. Our results indicate that VPA could be a promising agent in combined anticancer therapy for ovarian cancer, with the combination of VPA and DOX being the most effective. Certainly, additional in vivo and ex vivo experiments are necessary to investigate the molecular mechanisms of action underlying the cellular effects reported here and to study possible clinically relevant effects in ovarian cancer explants.

    Primary treatment of basal cell carcinoma of the lower eyelid and the inner corner is essentially surgical, but advanced lesions require extensive surgical interventions. In some cases it is necessary to continue with the mutilating surgery--exenteration of the orbit. In this work we evaluate the indications of radical solutions in patients with basal cell carcinoma invading the orbit and the subsequent possibility for individually made prosthesis to cover the defect of the cavity. Indications to exenteration of the orbit in patients with basal cell carcinoma findings in 2008-2013. Case report of 2 patients. In period 2008-20013 at the Dept. of Ophthalmology, Comenius University in Bratislava totally 221 patients with histologically confirmed basal cell carcinoma of the eyelids and the inner corner were treated. In 5 cases (2.7 %) with infiltration of the orbit the radical surgical procedure, exenteration was necessary. In 3 patients exenteration was indicated as the first surgical procedure in the treatment of basal cell carcinoma, since they had never visited ophthalmologist before only at in the stage of infiltration of the orbit (stage T4). In one case was indicated exenteration after previous surgical interventions and relapses. After healing the cavity patients got individually prepared epithesis. Surgical treatment of basal cell carcinoma involves the radical removal of the neoplasm entire eyelid and stage T1 or T2 can effectively cure virtually all tumors with satisfactory cosmetic and functional results. In advanced stages (T4 stage) by infiltrating the orbit by basal cell carcinoma exenteration of the orbit is necessary. This surgery is a serious situation for the patient and also for his relatives. Individually made prosthesis helps the patient to be enrolled to the social environment.

    The hedgehog pathway inhibitor sonidegib demonstrated meaningful tumor shrinkage in more than 90% of patients with locally advanced basal cell carcinoma (BCC) or metastatic BCC in the BCC Outcomes with LDE225 Treatment study. This report provides long-term follow-up data collected up to 12 months after the last patient was randomized. In this multicenter, randomized, double-blind phase II study, patients were randomized 1:2 to sonidegib 200 or 800 mg. The primary end point was objective response rate assessed by central review. Objective response rates in the 200- and 800-mg arms were 57.6% and 43.8% in locally advanced BCC and 7.7% and 17.4% in metastatic BCC, respectively. Among the 94 patients with locally advanced BCC who responded, only 18 progressed or died and more than 50% had responses lasting longer than 6 months. In addition, 4 of 5 responders with metastatic BCC maintained an objective response. Grade 3/4 adverse events and those leading to discontinuation were less frequent with sonidegib 200 versus 800 mg (38.0% vs 59.3%; 27.8% vs 37.3%, respectively). No placebo or comparator arms were used because sonidegib demonstrated efficacy in advanced BCC in a phase I study, and the hedgehog pathway inhibitor vismodegib was not yet approved. With longer follow-up, sonidegib demonstrated sustained tumor responses in patients with advanced BCC. Copyright © 2016 American Academy of Dermatology, Inc. Published by Elsevier Inc.

    Ultraviolet light (UV) is an important risk factor for cutaneous basal cell carcinoma, cutaneous squamous cell carcinoma and cutaneous melanoma of the skin. These cancers most commonly affect persons with fair skin and blue eyes who sunburn rather than suntan. However, each of these cancers appears to be associated with a different pattern of UV exposure and to be mediated by different intracellular molecular pathways.Some melanocortin 1 receptor (MC1R) gene variants play a direct role in the pathogenesis of cutaneous basal cell carcinoma, cutaneous squamous cell carcinoma and cutaneous melanoma apart from their role in determining a cancer-prone pigmentory phenotype (fair skin, red hair, blue eyes) through their interactions with other genes regulating immuno-inflammatory responses, DNA repair or apoptosis.In this short review we focus on the aetiological role of UV in cutaneous basal cell carcinoma, cutaneous squamous cell carcinoma and cutaneous melanoma of the skin, and on some associated biopathological events.

  4. Renal cell carcinoma: evolving approaches to advanced non-clear cell carcinoma

    Daniel Y.C. Heng

    2011-12-01

    Full Text Available The treatment of metastatic renal cell carcinoma (RCC has changed dramatically with the introduction of targeted therapies including sunitinib, sorafenib, and temsirolimus. Because patients with conventional clear cell histology account for 75- 80% of all patients with RCC, there has been little accumulated evidence on the treatment of patients with non-clear cell histologies. Most clinical trials have excluded them from enrolment, except for randomized studies investigating temsirolimus. Many retrospective studies on the use of all three of these targeted therapies in patients with non-clear cell histology have demonstrated response rates ranging from 3.7%–16%. Although response rates may not be as high compared to patients with clear cell histologies, targeted therapy does provide a clinically meaningful response.

    Full Text Available Abstract Background Rectal squamous cell carcinoma (SCC is a rare tumor. The incidence of this malignancy has been reported to be 0.25 to 1 per 1000 colorectal carcinomas. From a review of the English literature 55 cases of SCC of the rectum have been published. In this study we report a rectal metastatic SCC to the liver, discussing the efficacy of aggressive adjuvant and neo-adjuvant therapies on survival and prognosis. Case presentation A 39-year-old female patient with a pure SCC of the rectum diagnosed endoscopically is presented. The patient underwent initially neoadjuvant chemo-radiotherapy and then abdominoperineal resection with concomitant bilateral oophorectomy and hysterectomy, followed by adjuvant chemo-radiotherapy. Five months after the initial operation liver metastasis was demonstrated and a liver resection was carried out, followed by adjuvant chemotherapy. Eighteen months after the initial operation the patient is alive. Conclusion Although prognosis of rectal SCC is worse than that of adenocarcinoma, an aggressive therapeutic approach with surgery as the primary treatment, followed by combined neo- and adjuvant chemo-radiotherapy, may be necessary in order to improve survival and prognosis.

    A 71-year-old man underwent simple enucleation for T1a renal cell carcinoma of the left kidney 10 years ago, and, the capsule of the tumor was injured during that surgery. The histopathological diagnosis of the tumor was papillary renal cell carcinoma type1 pT1a, G2 and the surgical margin was negative. Eight years after the surgery, computed tomography (CT) scan imaging showed a mass 13 mm in diameter which was adjacent to the left kidney. In the following year, the mass had grown to 22 mm in diameter. Thus it was suspected as local recurrence of renal cell carcinoma. Magnetic resonance imaging revealed multiple tumors in the left perirenal fatty space and positron emission tomography CT showed abnormal uptake in the same lesions with a maximal standardized uptake value of 3.2. We diagnosed multiple local recurrences of renal cell carcinoma and planned open radical nephrectomy and extirpation of perirenal fat including tumors entirely. The histopathological diagnosis of the tumor was papillary renal cell carcinomas type 1, Fuhrman grade 2>3. The patient had no recurrence or metastases 10 months after the surgery. It is possible that the tumor cells were disseminated during the first surgery due to an injury to the capsule of the tumor and resulted in multiple local recurrences.

    Assessment of nodal response after radiotherapy (RT) for head and neck squamous cell carcinoma is difficult, as both CT and positron emission tomography scanning have limited predictive value for residual disease. We sought to measure changes in nodal volume during RT to determine whether such changes are predictive of nodal disease control. Patients with locally advanced head and neck squamous cell carcinoma treated with 70Gy of radical RT (±chemotherapy or anti-epidermal growth factor receptor (EGFR) antibodies) were eligible. Baseline pre-RT scans and cone-beam CT scans done at the outset of treatment and at weeks 3, 5 and 7 (cone-beam CTs 1, 2, 3 and 4, respectively) were deformably coregistered, and 3D nodal volumes were measured. Thirty-eight eligible patients were identified. The main primary tumour site was oropharyngeal; most patients had stage IVa disease. Twenty-seven patients received concurrent platinum-based chemotherapy, 10 received only an EGFR inhibitor with RT and one received RT alone. Twelve patients had a failure in the neck. After week 1 of treatment, a 4% mean decrease in nodal volume was observed, increasing to 40% at week 7. Platinum-based chemotherapy achieved significantly greater decreases in nodal volume than EGFR inhibitors (44 vs. 25%; P=0.026). Advanced tumour stage predicted neck failure (P=0.002), but nodal volumes did not correlate with neck control. Changes in nodal volume are minimal initially during RT but accelerate during the latter weeks of therapy. This study suggests that chemotherapy achieves a greater decrease in nodal volume than EGFR inhibitors and that nodal changes do not predict disease control in the neck.

    Full Text Available Abstract Introduction The differential diagnosis of neutropenia includes medications, infections, autoimmune diseases, and deficiencies of Vitamin B12 and folate. The association of Vitamin B6 deficiency with severe neutropenia is a rare finding. Case presentation A 51-year-old Caucasian woman presented with fever and profound neutropenia (48 neutrophils/uL. Her clinical history included non-Hodgkin lymphoma, in remission following treatment with allogeneic bone marrow transplantation, quiescent chronic graft-versus-host disease, and squamous cell carcinoma of the skin metastatic to cervical lymph nodes. Medications included atenolol, topical clobetasol, Ditropan (oxybutynin, prophylactic voriconazole, prophylactic valganciclovir, Soriatane (acitretin, and Carac (fluorouracil cream. The bone marrow was hypocellular without metastatic cancer or myelodysplasia. Neutropenia did not respond to stopping medications that have been associated with neutropenia (valganciclovir, voriconazole and Soriatane or treatment with antibiotics or granulocyte colony stimulating factor. Blood tests revealed absence of antineutrophil antibodies, normal folate and B12 levels, moderate zinc deficiency and severe Vitamin B6 deficiency. Replacement therapy with oral Vitamin B6 restored blood vitamin levels to the normal range and corrected the neutropenia. Her cervical adenopathy regressed clinically and became negative on scintography following Vitamin B6 therapy and normalization of the blood neutrophil count. Conclusion Severe pyridoxine deficiency can lead to neutropenia. Screening for Vitamin B6 deficiency, along with folate and Vitamin B12 levels, is recommended in patients with refractory neutropenia, especially those with possible malabsorption syndromes, or a history of chronic-graft-versus host disease. Severe neutropenia may facilitate progression of squamous cell carcinoma.

    International guidelines for management of basal cell carcinoma are reviewed and analyzed for decision-making in the appropriate therapeutic behavior for patients. The different therapies for the treatment of basal cell carcinoma are described. Different therapies are evaluated according to the risk (low or high) of recurrence to determine the appropriate treatment. According to the evidence, low-risk tumors have responded to topical therapy, curettage and electrodesiccation, cryotherapy or simple resection, and high-risk tumors are managed with surgery, radiotherapy or Mohs' micrographic surgery [es

    Vismodegib is a Hedgehog signaling pathway inhibitor recently approved by the US Food and Drug Administration for advanced basal cell carcinoma. We present 2 cases of clinically significant squamous cell carcinoma within the tumor bed of locally advanced basal cell carcinoma found during vismodegib treatment. The first case is that of a patient with locally advanced basal cell carcinoma responsive to vismodegib but with an enlarging papule within the tumor bed. On biopsy, this papule was an invasive acantholytic squamous cell carcinoma. The second case is that of a patient with Gorlin syndrome with a locally advanced basal cell carcinoma that was stable while the patient was receiving therapy with vismodegib for 2.5 years but subsequently increased in size. Biopsy specimens from this tumor showed invasive squamous cell carcinoma, spindle cell subtype. In both cases, the squamous cell carcinomas were surgically resected. These cases highlight the importance of repeated biopsy in locally advanced basal cell carcinomas in 2 clinical situations: (1) when an area within the tumor responds differentially to vismodegib, and (2) when a tumor stops being suppressed by vismodegib. Timely diagnosis of non-basal cell histologic characteristics is critical to institution of effective therapy.

    The aim of the present work was to implement the kinetics of cisplatin into a previously developed tumour growth model and to simulate the combined cisplatin-radiotherapy treatment with the emphasis on time sequencing and scheduling of drug and radiation. An investigation into whether the effect of cisplatin-radiation is determined by independent cell kill or by cisplatin-produced radiosensitization was also undertaken. It was shown that cisplatin administered before radiation conferred similar tumour control to the post-radiation sequencing of the drug. The killing effect of the combined modality treatment on tumour increased with the increase in cell recruitment. Furthermore, the individual cell kill produced by the two cytotoxins led to an additive only tumour response when the treatments were given concurrently, suggesting that for a synergistic effect, cisplatin must potentiate the effect of radiation, through the radiosensitizing mechanisms addressed in the literature. It was concluded that the optimal timing of cisplatin should be close to radiation. The model showed that daily administration of cisplatin led to a 35% improvement of tumour control as compared to radiation alone, while weekly cisplatin has improved radiotherapy by only 6%

    The development of basal cell carcinoma, the commonest human cancer in fair skinned populations, is clearly associated with constitutive activation of sonic hedgehog signaling. Insight into the genesis of BCC came from the identification of germline mutations of the tumor suppressor gene, PATCHED, a key regulatory component of hedgehog signaling in the nevoid basal cell carcinoma syndrome. Analysis of sporadic basal cell carcinomas and those from repair deficient xeroderma pigmentosum patients has revealed mutational inactivation of PATCHED and gain of function mutations of the proto-oncogenes, SMOOTHENED and SONIC HEDGEHOG associated with solar UV exposure. The molecular mechanisms involved in alterations of the hedgehog signaling pathway that lead to the formation of basal cell carcinomas are being unraveled and has already allowed the investigation of future therapeutic strategies for treating these skin cancers.

    Basal cell carcinoma is the most common cancer, presenting low mortality but high morbidity, and it has as risk factor exposure to sunlight, especially UVB spectrum. The most important constitutional risk factors for basal cell carcinoma development are clear phototypes (I and II, Fitzpatrick classification), family history of basal cell carcinoma (30-60%), freckles in childhood, eyes and light hair. The environmental risk factor better established is exposure to ultraviolet radiation. However, different solar exposure scenarios probably are independent risk factors for certain clinical and histological types, topographies and prognosis of this tumor, and focus of controversy among researchers. Studies confirm that changes in cellular genes Hedgehog signaling pathway are associated with the development of basal cell carcinoma. The cellular Hedgehog signaling pathway is activated in organogenesis, but is altered in various types of tumors. PMID:28954101

    To review the literature on targeted therapy for orbital and periocular basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (SCC) and provide examples of patients recently treated with such therapy. The authors reviewed the literature on clinical results of targeted therapy and the molecular basis for targeted therapy in orbital and periocular BCC and cutaneous SCC. The authors also present representative cases from their practice. Mutation in the patched 1 gene (PTCH1) has been implicated in BCC, and overexpression of epidermal growth factor receptor (EGFR) has been shown in SCC. Vismodegib, an inhibitor of smoothened, which is activated upon binding of hedgehog to Ptc, has been shown to significantly decrease BCC tumor size or even produce complete resolution, especially in cases of basal cell nevus syndrome. Similarly, EGFR inhibitors have been shown to significantly decrease SCC tumor size in cases of locally advanced and metastatic disease. The authors describe successful outcomes after vismodegib treatment in a patient with basal cell nevus syndrome with numerous bulky lesions of the eyelid and periocular region and erlotinib (EGFR inhibitor) treatment in a patient with SCC who was deemed not to be a good surgical candidate because of advanced SCC of the orbit with metastasis to the regional lymph nodes, advanced age, and multiple medical comorbidities. Targeted therapy using hedgehog pathway and EGFR inhibitors shows significant promise in treatment of orbital and periocular BCC and cutaneous SCC, respectively. Such targeted therapy may be appropriate for patients who are not good candidates for surgery.

    Purpose: Recent cell culture studies by us and others suggest that some human carcinoma cells are more sensitive to heat than are rodent cells following mild hyperthermia. In studying the cellular mechanism of enhanced thermosensitivity of human tumor cells to hyperthermia, prostatic carcinoma cells of human origin were found to be more sensitive to mild hyperthermia than other human cancer cells. The present study was designed to determine the magnitude of radiosensitization of human prostatic carcinoma cells by mild hyperthermia and to examine whether the thermal radiosensitization is related to the intrinsic thermosensitivity of cancer cells. Methods and Materials: Two human prostatic carcinoma cell lines (DU-145 and PC-3) and other carcinoma cells of human origin, in particular, colon (HT-29), breast (MCF-7), lung (A-549), and brain (U-251) were exposed to temperatures of 40-41 deg. C. Single acute dose rate radiation and fractionated radiation were combined with mild hyperthermia to determine thermal radiosensitization. The end point of the study was the colony-forming ability of single-plated cells. Results: DU-145 and PC-3 cells were found to be exceedingly thermosensitive to 41 deg. C for 24 h, relative to other cancer cell lines. Ninety percent of the prostatic cancer cells were killed by a 24 h heat exposure. Prostatic carcinoma cells exposed to a short duration of heating at 41 deg. C for 2 h resulted in a substantial enhancement of radiation-induced cytotoxicity. The thermal enhancement ratios (TERs) of single acute dose radiation following heat treatment 41 deg. C for 2 h were 2.0 in DU-145 cells and 1.4 in PC-3 cells. The TERs of fractionated irradiation combined with continuous heating at 40 deg. C were similarly in the range of 2.1 to 1.4 in prostate carcinoma cells. No significant radiosensitization was observed in MCF-7 and HT-29 cells under the same conditions. Conclusion: The present data suggest that a significant radiosensitization of

    Apoptosis, or programmed cell death, plays an important role in many physiological and diseased conditions. Induction of apoptosis in cancer cells by anti-cancer drugs and biosynthetic inhibitors of cells surface glycolipids in the human colon carcinoma cells (Colo-205) are of interest in recent years. In our present studies, we have employed different stereoisomers of PPMP and PDMP (inhibit GlcT-glycosyltransferase (GlcT-GLT)) to initiate apoptosis in Colo-205 cells grown in culture in the presence of (3)H-TdR and (3)H/or (14)C-L-Serine. Our analysis showed that the above reagents (between 1 to 20 microM) initiated apoptosis with induction of Caspase-3 activities and phenotypic morphological changes in a dose-dependent manner. We have observed an increase of radioactive ceramide formation in the presence of a low concentration (1-4 microM) of these reagents in these cell lines. However, high concentrations (4-20 microM) inhibited incorporation of radioactive serine in the higher glycolipids. Colo-205 cells were treated with L-threo-PPMP (0-20 microM) and activities of different GSL: GLTs were estimated in total Golgi-pellets. The cells contained high activity of GalT-4 (UDP-Gal: LcOse3Cer beta 1-4galactosyltransferase), whereas negligible activity of GalT-3 (UDP-Gal: GM2 beta 1-3galactosyltransferase) or GM2-synthase activity of the ganglioside pathway was detected. Previously, GLTs involved in the biosynthetic pathway of SA-Le(x) formation had been detected in these colon carcinoma (or Colo-205) cells (Basu M et al. Glycobiology 1, 527-35 (1991)). However, during progression of apoptosis in Colo-205 cells with increasing concentrations of L-PPMP, the GalT-4 activity was decreased significantly. These changes in the specific activity of GalT-4 in the total Golgi-membranes could be the resultant of decreased gene expression of the enzyme.

  2. Vismodegib (ERIVEDGE°) In basal cell carcinoma: too many unknowns.

    Science.gov (United States)

    2015-01-01

    Basal cell carcinomas are the most common skin cancers. They are usually localised and carry a good prognosis. There is no standard treatment for the rare patients with metastatic basal cell carcinoma or very extensive basal cell carcinoma for whom surgery or radiotherapy is inappropriate. Vismodegib, a cytotoxic drug, is claimed to prevent tumour growth by inhibiting a pathway involved in tissue repair and embryogenesis. It has been authorised in the European Union for patients with metastatic or locally advanced and extensive basal cell carcinoma. Clinical evaluation of vismodegib is based on a non-comparative clinical trial involving 104 patients, providing only weak evidence. Twenty-one months after the start of the trial, 7 patients with metastases (21%) and 6 patients with advanced basal cell carcinoma (10%) had died. Given the lack of a placebo group, there is no way of knowing whether vismodegib had any effect, positive or negative, on survival. There were no complete responses among patients with metastases, but about one-third of them had partial responses. Among the 63 patients with locally advanced basal cell carcinoma, there were 14 complete responses and 16 partial responses. The recurrence rate in patients with complete responses was not reported. Similar results were reported in two other uncontrolled trials available in mid-2014. Vismodegib has frequent and sometimes serious adverse effects, including muscle spasms, fatigue and severe hyponatraemia. Cases of severe weight loss, alopecia, ocular disorders, other cancers (including squamous cell carcinoma) and anaemia have also been reported. More data are needed on possible hepatic and cardiovascular adverse effects. A potent teratogenic effect was seen in experimental animals. As vismodegib enters semen, contraception is mandatory for both men (condoms) and women. In practice, vismodegib has frequent and varied adverse effects, some of which are serious, while its benefits are poorly documented

    We evaluated sociodemographic and economic differences in overall survival (OS) of patients with penile SCC using the National Cancer Data Base (NCDB). We identified 5,412 patients with a diagnosis of penile squamous cell carcinoma from 1998 to 2011 with clinically nonmetastatic disease and available pathologic tumor and nodal staging. OS was estimated using the Kaplan-Meier method, and differences were determined using the log-rank test. Cox proportional hazard regression was performed to identify independent predictors of OS. Estimated median OS was 91.9 months (interquartile range: 25.8-not reached) at median follow-up of 44.7 months (interquartile range: 17.2-81.0). Survival did not change over the study period (P = 0.28). Black patients presented with a higher stage of disease (pT3/T4: 16.6 vs. 13.2%, P = 0.027) and had worse median OS (68.6 vs. 93.7 months, P<0.01). Patients with private insurance and median income≥$63,000 based on zip code presented with a lower stage of disease (pT3/T4: 11.6 vs. 14.7%, P = 0.002 and 12.0 vs. 14.0%, P = 0.042, respectively) and had better median OS (163.2 vs. 70.8 months, P<0.01 and 105.3 vs. 86.4 months, p = 0.001, respectively). On multivariate analysis, black race (hazard ratio [HR]: 1.39, 95% confidence interval [CI]: 1.21-1.58; P<0.01) was independently associated with worse OS, whereas private insurance (HR = 0.79, 95% CI: 0.63-0.98; P = 0.028) and higher median income≥$63,000 (HR = 0.82; 95% CI: 0.72-0.93; P = 0.001) were independently associated with better OS. Racial and economic differences in the survival of patients with penile cancer exist. An understanding of these differences may help minimize disparities in cancer care.

    Pegylated liposomal doxorubicin (PLD) has a good safety profile, but long-term use has been associated with development of squamous cell carcinoma of the tongue and oral cavity (SCCTO) in some patients. The study objective was to estimate the prevalence of oral leukoplakia, a known precursor of SCCTO, in patients with ovarian cancer and long-term PLD use.After approval of the institutional review board, medical record of 114 patients who were treated with PLD at our institution between January 2010 and December 2016 were retrospectively reviewed. All those patients have been referred for routine monitoring of oral mucositis every time before administration by a dentist. The patient characteristics included in the evaluation were age, smoking and drinking habits, the PLD dose and schedule, and presence or absence of oral leukoplakia and SCCTO at each oral examination. The relationships of the incidence of oral leukoplakia and patient characteristics were analyzed.The median total PLD dose was 160 (range 40-1550) mg/m. Oral leukoplakia was seen in 6 (5.3%) patients. The median PLD dose, at the time of oral leukoplakia diagnosis, was 685 (range 400-800) mg/m. SCCTO was not found. Univariate analysis revealed that age, Brinkman index, and habitual drinking were not considered as risk factors for oral leukoplakia, and only total PLD dose (OR, 1.470; 95% CI, 1.19-1.91; P oral leukoplakia. The ROC curve analysis indicated that the optimal cutoff value of the total PLD dose to predict development of oral leukoplakia was 400 mg/m. The sensitivity was 100% and the specificity was 88.8%. No patient discontinued PLD because of oral leukoplakia or SCCTO.The 2 most important clinical observations were the occurrence of oral leukoplakia in patients with long-term PLD use and that the development of oral leukoplakia was related to a total cumulative dose ≥400 mg/m. Routine oral surveillance is recommended, particularly when the cumulative total dose exceeds 400 mg/m.

    The traditional treatment for lacrimal gland carcinoma is orbital exenteration followed by radiation therapy. However, orbital exenteration does not prevent distant relapse and death, and some patients experience local-regional recurrence after exenteration. More recently, eye-sparing surgery and adjuvant radiation therapy and chemotherapy have gained popularity in the treatment of lacrimal gland carcinoma. Preliminary studies show that these approaches are associated with reasonable local control rates and ocular toxicity profiles. In this review, we discuss recent studies of treatment of lacrimal gland carcinoma, including studies of potential molecular treatment targets. Recent studies suggest promising results for neoadjuvant intra-arterial chemotherapy followed by orbital exenteration and adjuvant intravenous chemotherapy, but only in patients with an 'intact lacrimal artery'. Recent studies of globe-sparing surgery followed by adjuvant proton radiation therapy or concurrent chemoradiation suggest good local control, reasonable rates of eye preservation, and low risk of serious ocular toxic effects. Larger tumor size and predominant basaloid histology seem to be associated with higher risk of local-regional recurrence and distant metastasis. One study showed oncogenic mutations in more than half of cases of lacrimal gland adenoid cystic carcinoma, with KRAS mutations in 10 of 24 patients, suggesting potential benefit of treatments targeting the EGFR-RAS-RAF cascade. In selected patients with lacrimal gland carcinoma, eye-sparing surgery with eye-sparing radiation therapy offers preservation of visual function with good local control and minimal radiation-induced ocular toxic effects. In patients with recurrent or metastatic disease, a search for actionable cancer-associated mutations may be prudent.

    To report two cases of late metastases of clear cell renal cell carcinoma. Two patients, a male and a female with history of nephrectomy 17 and 16 years before for renal cell carcinomas, presented new tumours in the thyroid and pancreas, which were excised. Pathology reported that both lesions were clear cell tumours and immunohistochemically they were consistent with metastases from clear renal cell carcinomas. 1) Previous history of any type of carcinoma should suggest the possibility of metastases when facing a thyroid or pancreatic nodule. 2) All-life follow-up should be made, nephrectomy (resection) for a renal cell carcinoma. 3) In the presence of a clear cell tumour of the thyroid or pan-creatic glands, the differential diagnosis must always include metastatic renal cell carcinoma. 4) The treatment of choice is surgical resection.

    Understanding the molecular basis of basal cell carcinoma (BCC) has led to development of Hedgehog pathway inhibitors (HPIs) for patients with advanced forms of BCC (aBCC). A practical definition of aBCC as a distinct disease entity is unavailable, and epidemiological information is limited. To conduct the RONNIE study to describe characteristics, treatment patterns, and outcomes of patients with aBCC during the period preceding HPI introduction, as well as results from patients with locally advanced BCC (laBCC). A retrospective chart review was conducted using data from adult patients with a new diagnosis of laBCC between 1 st January 2005 and 31 st December 2010. The study period was 1 st January 2005 to 31 st December 2011 to allow for inclusion of at least 12 months of follow-up information for all patients. Treatment data were available for 106/117 patients. Radiation and excisional surgery were the most common first-line treatment options (43.4% and 23.5% of patients, respectively). Patients typically received multiple subsequent treatments; no apparent trend or pattern was observed. Complete visual response, partial visual response, and stable disease were obtained in 51.9%, 25.9%, and 11.1% of patients, respectively, after first-line surgery, and in 53.7%, 22.0%, and 9.8%, respectively, after first-line radiation. Median progression-free survival after first-line treatment was 32.1 months. Median overall survival was 78.8 months. These data represent a baseline for laBCC before HPIs became part of the treatment algorithm. The observed heterogeneity of treatment patterns highlights the lack of an established standard treatment for laBCC before HPIs were available.

  9. Treatment of well-differentiated thyroid carcinoma

    Improved selection of thyroid nodules for surgery and greater individualization of surgery for well-differentiated thyroid carcinoma are emphasized. Thyroid nodules are common but infrequently are manifestations of carcinoma. Needle biopsy permits better selection of patients with thyroid nodules for surgery by identifying those which are malignant or are likely to become malignant. Experience in performing diagnostic needle biopsies and in cytologic and histologic interpretation is essential. The majority of well-differentiated thyroid carcinomas are well-localized papillary carcinomas controlled by surgery, usually a lobectomy or partial thyroidectomy. Well-differentiated thyroid carcinomas include papillary and follicular types and their subsets. The extent of surgery should be individualized based on gross extent of disease, histologic variety, and age of the patient. The prognosis is reduced for patients more than 40 years of age. With appropriate early surgical treatment, the outlook is excellent. Metastatic disease can frequently also be controlled by large doses of thyroid hormone and the use of radioactive iodine

    1990-09-01

    Attempting to improve local disease control in bulky primary or recurrent pelvic tumors, 29 patients with squamous cell carcinoma of the cervix were treated with concomitant chemotherapy and split-course hyperfractionated radiation therapy between April 1983 and August 1988. Cisplatin (CDDP) and 5-fluorouracil (5-FU) have been shown to be radiation enhancers; furthermore, CDDP, radiation therapy, and continuous-infusion 5-FU have elicited high local response rates in head and neck squamous cell carcinoma. A pilot study of cyclical week on/week off CDDP, continuous-infusion 5-FU, and hyperfractionated radiation therapy was developed. Radiation was administered at 116 cGy twice daily, Days 1-5, every other week for a median dose of 4600 cGy to a pelvic field, with paraaortic extension if indicated. Concomitant chemotherapy included CDDP 60 mg/m2 IV Day 1 and 5-FU 600 mg/m2 IV continuous infusion for 96 hr following CDDP infusion. Patients received a median of four cycles of combined treatment, and intracavitary or interstitial brachytherapy followed in 21 patients. Local pelvic response was achieved in 29 of 29 (100%): complete response (CR) in 19 of 29 (66%), partial response (PR) in 10 of 29 (34%). Among CR patients 10 of 19 (53%) were without evidence of disease at a mean follow-up of 29 (range 12-76) months. Five-year actuarial disease-free survival among complete responders was 65%. Of the 10 CR patients 2 failed in the pelvis, for a local control rate of 17/19 (89%). Chemotherapy-related and acute radiation morbidity was minimal but 2 patients required surgical correction of radiation injury. Aggressive combination of split-course hyperfractionated radiation therapy with radiation enhancers resulted in promising local control of bulky pelvic tumor, with an acceptable complication rate, in this otherwise very poor prognostic group of patients.

Familial follicular cell-derived well-differentiated thyroid cancers contribute to 5% of those cases. These familial follicular cell derived carcinomas or non-medullary thyroid carcinomas (NMTC divide into two clinical-pathological groups. One group, syndromic-associated, composed by predominately non-thyroidal tumors, is comprised of Pendred syndrome, Warner syndrome, Carney complex type 1, PTEN-hamartoma tumor syndrome (Cowden disease; PHTS, familial adenomatous polyposis (FAP/Gardner syndrome. Additionally other less established links correlated to the development of follicular cell-derived tumors have also included Ataxia-teleangiectasia syndrome, McCune Albright syndrome, and Peutz-Jeghers syndrome. The subsequent group encompasses syndromes typified by non-medullary thyroid carcinomas or NMTC, as well as, pure familial (f PTC with or without oxyphilia, fPTC with multinodular goiter and fPTC with papillary renal cell carcinoma. This heterogeneous group of diseases has not a established genotype-phenotype correlation as the well-known genetic events identified in the familial C-cell-derived tumors or medullary thyroid carcinomas (MTC. Clinicians should be have the knowledge to identify the likelihood of a patient presenting with thyroid cancer having an additional underlying familial syndrome stemming from characteristics through morphological findings that would alert the pathologist to have the patient undergo subsequent molecular genetics evaluations. This review will discuss the clinical and pathological findings of the patients with familial papillary thyroid carcinoma, such as familial adenomatous polyposis, Carney complex, Werner syndrome, and Pendred syndrome and the heterogeneous group of familial papillary thyroid carcinoma.

    The aim of the present study was to gain more insight into the natural history of endometrial carcinoma, to evaluate prognostic factors and to assess the various treatment methods and the results. Using the data of the Norwegian Radium Hospital, where treatment of gynecological cancer is centralized to a great extent, a large series of patients with long term follow-up, covering all clinical stages and recurrences of endometrial carcinoma, could be evaluated. This resulted in five articles. These articles, together with a study from the University Hospital in Groningen are presented and discussed, and recommendations for treatment are given. The relevant treatments assessed are postoperative external irradiation, preoperative uterine radium packing, preoperative low dose external irradiation and radiotherapy alone. (Auth.)

    This article presents a review of the literature regarding the use of transcatheter arterial chemoembolization (TACE) in the treatment of hepatocellular carcinoma (HCC). There have been two different approaches to the treatment: (a) percutaneous tumor ablation methods which can be divided into injectable and thermal methods; percutaneous ethanol injection (PEI) is the most widely used method, and (b) TACE. PEI is the treatment of choice for single HCCs smaller or equal to 3 cm in size. For patients with large HCCs combined TACE and PEI is probably the most effective nonsurgical treatment. In the presence of multiple HCC nodules, TACE remains the treatment of choice

    Chronic lymphocytic leukemia (CLL) is a monoclonal disorder, characterized by a progressive proliferation of functionally incompetent B lymphocytes. There is increased evidence of association between CLL and skin cancers, including the uncommon Merkel cell carcinoma (MCC). A case report of an 84-year old male, who presented with an aggressively recurrent form of MCC on the lower lip, on the background of an 8-year history of untreated CLL. During the recurrences of MCC, coexisting regional lymphadenopathy, posed a problem in the differential diagnosis and treatment of lymph node involvement. Histopathology and immunoistochemistry showed that submandibular lymphadenopathy coexisting with the second recurrence of MCC, was due to B-cell small lymphocytic lymphoma. The subsequent and more aggressive recurrence of the skin tumor had involved the superficial and deep cervical lymph nodes. Surgical excision followed by involved field radiation therapy has been proven effective for both malignancies. MCC has a high incidence of regional lymphadenopathy at presentation (12–45%) and even when it arises on the background of chronic leucemia, lymphadenopathy at presentation should be managed agressively with elective lymph node dissection. We overview the postulated correlation between Merkel tumor and CCL, the differential diagnosis of regional lymphadenopathy during the recurrences of the skin tumor and the strategies of treatment

    Basal cell carcinoma is the most common skin cancer, characterised by a slow growing behavior, metastasis are extremely rare, and it occurs in less than 0, 1% of all cases. Giant basal cell carcinoma is a rare form of basal cell carcinoma, more aggressive and defined as a tumor measuring more than 5 cm at its largest diameter. Only 1% of all basal cell carcinoma develops to a giant basal cell carcinoma, resulting of patient's negligence. Giant basal cell carcinoma is associated with higher potential of metastasis and even death, compared to ordinary basal cell carcinoma. We report a case of giant basal cell carcinoma metastaticin lung occurring in a 79 years old male patient, with a fatal evolution after one course of systemic chemotherapy. Giant basal cell carcinoma is a very rare entity, early detection of these tumors could prevent metastasis occurrence and improve the prognosis of this malignancy.

    Full Text Available OBJECTIVE: The therapeutic effect of middle frontal horizontal partial laryngectomy (MFHPL in treating stage T1b squamous cell carcinoma of the glottic larynx involving anterior vocal commissure (AVC was compared with that of the anterior frontolateral vertical partial laryngectomy (AFVPL. The feasibility and practical significance of MFHPL in clinical application was discussed in the present study. METHODS: From January 1996 to January 2010, a total of 65 patients diagnosed with stage T1bN0M0 glottic laryngeal cancer were treated with MFHPL or AFVPL. The postoperative complications, glottic reconstruction, recurrence rate, voice quality and survival rates were evaluated and compared between two treatments. RESULTS: AFVPL and MFHPL were performed in 34 and 31 patients, respectively. Flexible fiberoptic laryngoscopy revealed that in the MFHPL-treated patients the reconstructed glottis was spacious and symmetric. In contrast, AFVPL treatment resulted in irregular glottic area with poor symmetry and tubular glottis. The incidence of postoperative laryngeal stenosis significantly differed between the MFHPL- and AFVPL-treated groups (P = 0.025. No significant difference was detected in the 3- and 5-year overall- or tumor-free survival rates between two treatments. The Voice Handicap Index (VHI and maximum phonation time (MPT after surgery were 51.0±12.99 and 12.42±3.44 sec in the AFVPL-treated group; while in the MFHPL-treated patients they were 31.81±7.48 and 7.65±1.98 sec, respectively. Both differences in VHI (P = 0.012 and MPT (P = 0.024 were significant between two treatments. CONCLUSIONS: MFHPL was comparable to AFVPL with respect to postoperative complications, recurrence rate and survival rates, but possessed advantages over AFVPL in terms of the incidence of laryngeal stenosis and voice quality. Our study indicated that MFHPL has a potential value in clinical practice of treating stage T1b squamous cell carcinoma of the

    Older adults with head and neck squamous cell carcinoma (HNSCC) pose unique treatment and supportive care challenges to oncologists and other cancer care providers. The majority of patients with HNSCC present with locoregionally advanced disease, for which combined-modality treatment integrating chemotherapy and radiation therapy is often necessary to maximize tumor control. However, applying these approaches to an older population with concomitant comorbidities and a higher risk of functional impairments remains challenging and is exacerbated by the paucity of studies involving older adults. The purpose of this article is to identify knowledge gaps in the evaluation and management of older adults with HNSCC-particularly those undergoing concurrent chemoradiation therapy-and their caregivers through a review of the literature conducted by clinicians, researchers, and patient advocates. The findings highlight the importance of a geriatric assessment and the therapeutic paradigms and challenges relevant to this population. Furthermore, we identify the need for additional research and interventions related to key supportive care issues that arise during and after treatment in older adults with locoregionally advanced HNSCC. On the basis of our findings, we prioritize these issues to guide future patient-oriented research endeavors to address these knowledge gaps and thus better serve this growing patient population.

    2006-01-01

    Purpose: To evaluate the prognostic significance of hemoglobin (Hb) levels measured before and during treatment with accelerated radiotherapy with carbogen and nicotinamide (ARCON). Methods and Materials: Two hundred fifteen patients with locally advanced tumors of the head and neck were included in a phase II trial of ARCON. This treatment regimen combines accelerated radiotherapy for reduction of repopulation with carbogen breathing and nicotinamide to reduce hypoxia. In these patients, Hb levels were measured before, during, and after radiotherapy. Results: Preirradiation and postirradiation Hb levels were available for 206 and 195 patients respectively. Hb levels below normal were most frequently seen among patients with T4 (p < 0.001) and N2 (p < 0.01) disease. Patients with a larynx tumor had significantly higher Hb levels (p < 0.01) than other tumor sites. During radiotherapy, 69 patients experienced a decrease in Hb level. In a multivariate analysis there was no prognostic impact of Hb level on locoregional control, disease-free survival, and overall survival. Primary tumor site was independently prognostic for locoregional control (p = 0.018), and gender was the only prognostic factor for disease-free and overall survival (p < 0.05). High locoregional control rates were obtained for tumors of the larynx (77%) and oropharynx (72%). Conclusion: Hemoglobin level was not found to be of prognostic significance for outcome in patients with squamous cell carcinoma of the head and neck after oxygen-modifying treatment with ARCON

    Estramustine (EM), an antimicrotubule agent, binds microtubule-associated proteins, causes spindle disassembly, and arrests cells at the late G 2 /M phase of the cell cycle. Since cells in the G 2 /M phase are the most radiosensitive and some human cancer cells contain high level of EM-binding protein, experiments were carried out to determine whether radiation sensitization could be obtained in human carcinoma cells. Cells containing a high level of EM-binding protein such as prostate carcinoma (DU-145), breast carcinoma (MCF-7), and malignant glioma (U-251) were used to demonstrate radiosensitization. Cervical carcinoma (HeLa-S 3 ) and colon carcinoma (HT-29) cells which are not known to contain EM-binding protein were also employed. Cell survival was assayed by the colony forming ability of single plated cells in culture to obtain dose-survival curves. Pretreatment of DU-145, MCF-7, and U-251 cells to a nontoxic concentration (5 μM) of EM for more than one cell cycle time, substantially enhanced the radiation-induced cytotoxicity. The sensitizer enhancement ratio of these cells ranged from 1.35-1.52. The magnitude of the enhancement was dependent on the drug concentration and exposure time. The rate of cell accumulation in G 2 /M phase, as determined by flow cytometry, increased with longer treatment time in the cell lines which showed radiosensitization. Other antimicrotubule agents such as taxol and vinblastine caused minimal or no radiosensitization at nontoxic concentrations. The data provide a radiobiological basis for using EM as a novel radiation enhancer, with the property of tissue selectivity. 29 refs., 4 figs., 1 tab

    Following the first descriptions of the dermatoscopic pattern of basal cell carcinoma (BCC) that go back to the very early years of dermatoscopy, the list of dermatoscopic criteria associated with BCC has been several times updated and renewed. Up to date, dermatoscopy has been shown to enhance BCC detection, by facilitating its discrimination from other skin tumors and inflammatory skin diseases. Furthermore, upcoming evidence suggests that the method is also useful for the management of the tumor, since it provides valuable information about the histopathologic subtype, the presence of clinically undetectable pigmentation, the expansion of the tumor beyond clinically visible margins and the response to non-ablative treatments. In the current article, we provide a summary of the traditional and latest knowledge on the value of dermatoscopy for the diagnosis and management of BCC. PMID:25126452

    Full Text Available The treatment of metastatic renal cell carcinoma (mRCC has changed dramatically in the past decade. As the number of available agents, and related volume of research, has grown, it is increasingly complex to know how to optimally treat patients. The authors are practicing medical oncologists at the US Oncology Network, the largest community-based network of oncology providers in the country, and represent the leadership of the Network's Genitourinary Research Committee. We outline our thought process in approaching sequential therapy of mRCC and the use of real-world data to inform our approach. We also highlight the evolving literature that will impact practicing oncologists in the near future.

    Basal cell carcinoma of the axilla, an area that is not usually exposed to the sun, is rare. Individuals with basal cell nevus syndrome, a disorder associated with a mutation in the patch 1 (PTCH1) gene, develop numerous basal cell carcinomas. To describe a woman with basal cell nevus syndrome who developed a pigmented basal cell carcinoma in each of her axilla and to review the features of axillary basal cell carcinoma patients with Goltz-Gorlin syndrome. Pubmed was used to search the following terms: axillary basal cell carcinoma and basal cell nevus syndrome. The papers and their citations were evaluated. Basal cell nevus syndrome patients with basal cell carcinoma of the axilla were observed in two women; this represents 2.5% (2 of 79) of the patients with axillary basal cell carcinoma. Both women had pigmented tumors that were histologically nonaggressive. The cancers did not recur after curettage or excision. Basal cell carcinoma of the axilla has only been described in 79 individuals; two of the patients were women with pigmented tumors who had basal cell nevus syndrome. Similar to other patients with axillary basal cell carcinoma, the tumors were histologically nonaggressive and did not recur following treatment. Whether PTCH1 gene mutation predisposes basal cell nevus patients to develop axillary basal cell carcinomas remains to be determined.

    Full Text Available Among the novel biologic therapeutics that will increase our ability to cure human cancer in the years to come, T cell therapy is one of the most promising approaches. However, with the possible exception of tumor-infiltrating lymphocytes therapy for melanoma, clinical trials of adoptive T-cell therapy for solid tumors have so far provided only clear proofs-of-principle to build on with further development. Epstein-Barr virus (EBV-associated malignancies offer a unique model to develop T cell-based immune therapies, targeting viral antigens expressed on tumor cells. In the last two decades, EBV-specific cytotoxic T-lymphocytes (CTL have been successfully employed for the prophylaxis and treatment of EBV-related lymphoproliferative disorders in immunocompromised hosts. More recently, this therapeutic approach has been applied to the setting of EBV-related solid tumors, such as nasopharyngeal carcinoma. The results are encouraging, although further improvements to the clinical protocols are clearly necessary to increase anti-tumor activity. Promising implementations are underway, including harnessing the therapeutic potential of CTLs specific for subdominant EBV latent cycle epitopes, and delineating strategies aimed at targeting immune evasion mechanisms exerted by tumor cells.

    In this report, a case of ocular scleral metastasis was reported in a patient with a past history of esophageal squamous cell carcinoma. The patient was a 58-year-old male who was admitted to Urmia Imam Khomeini Hospital, Urmia, Iran, 8 years ago with progressive dysphasia. Seven years after initial diagnosis and treatment of esophageal cancer, the patient had no signs or symptoms of the disease. But 2 months ago, he was referred to the hospital due to ocular swelling, redness and watering. Pathologic examination of the excised lesion at Farabi Hospital reported metastasis of squamous cell carcinoma to the connective tissue of the sclera.

    We report a case of a 73-year-old lady with transitional cell carcinoma and no evidence of metastatic disease presenting with gradual weight loss, pretibial swelling and painful weightbearing. Investigations revealed a lesion of the right tibial diaphysis. The radiological and clinical appearance was that of primary osteosarcoma. Biopsy results revealed metastatic transitional cell carcinoma of the tibia. Intramedullary nailing was performed which relieved pain on weightbearing. The patient declined radiotherapy and was started on a palliative care regimen. This case illustrates the importance of histological diagnosis in the treatment of diaphyseal lesions.

    Full Text Available Abstract Small cell carcinoma of the bladder (SCCB is rare, highly aggressive and diagnosed mainly at advanced stages. Hematuria is the main symptom of this malignancy. The origin of the disease is unknown; however the multipotent stem cell theory applies best to this case. Histology and immunohistochemistry shows a tumour which is indistinguishable from small cell lung carcinoma (SCLC. Coexistence of SCCB with other types of carcinoma is common. The staging system used is the TNM-staging of bladder transitional cell carcinoma. The treatment is extrapolated from that of SCLC. However, many patients with SCCB undergo radical resection which is rarely performed in SCLC. Patients with surgically resectable disease ( or = cT4bN+M+ should be managed with palliative chemotherapy based on neuroendocrine type regimens comprising a platinum drug (cisplatin in fit patients. The prognosis of the disease is poor mainly in the case of pure small cell carcinoma. Other research programs are needed to improve the outcome of SCCB.

    To assess the effectiveness, safety, and treatment patterns of anti-angiogenic agents in metastatic renal cell carcinoma (mRCC) in tertiary clinical practice settings. We retrospectively reviewed the medical records in two tertiary oncology centres in the USA for all patients treated while off clinical trials from April 2003 to June 2008 who met the entry criteria and received one or more prescriptions for sunitinib or sorafenib, or one or more intravenous administrations of bevacizumab (off-label) as first-line anti-angiogenic treatment. The objective response rate (ORR) reviewed by independent physicians, adverse events (AEs), and treatment modifications were assessed. Among 144 patients receiving sunitinib (57), sorafenib (62) and bevacizumab (25), the median treatment duration was 10.5, 8.1 and 7.9 months, and the ORR was 37%, 9% and 13%, respectively. The ORR was lower for patients with metastases to bone, brain, lungs or lymph nodes. Common AEs (all grades) for sunitinib were fatigue (53%), diarrhoea (37%); for sorafenib, diarrhoea (50%), fatigue (40%); for bevacizumab, fatigue (40%), nausea (24%). In all, 34 (60%), 51 (82%) and 20 (80%) patients receiving sunitinib, sorafenib and bevacizumab, respectively, discontinued treatment; 10 (18%), 11 (18%) and four (16%) discontinued due to AEs; 21%, 40% and 12% had a dose interruption, and 30%, 35% and 0% had a dose reduction. Currently available anti-angiogenic agents had considerable effectiveness in clinical practice. However, the response rates appeared to be low in certain subgroups, but sample sizes were small. Patients had significant rates of AEs, many of which led to treatment modifications. The findings from this retrospective study suggest that there is a need for better-tolerated therapies for mRCC.

    There is increasing evidence that primary tumor ablation can improve survival for some cancer patients with distant metastases. This may be particularly applicable to head and neck squamous cell carcinoma (HNSCC) because of its tropism for locoregional progression. This study included patients with metastatic HNSCC undergoing systemic therapy identified in the National Cancer Data Base. High-intensity local treatment was defined as radiation doses ≥ 60 Gy or oncologic resection of the primary tumor. Multivariate Cox regression, propensity score matching, landmark analysis, and subgroup analysis were performed to account for imbalances in covariates, including adjustments for the number and location of metastatic sites in the subset of patients with this information available. In all, 3269 patients were included (median follow-up, 51.5 months). Patients undergoing systemic therapy with local treatment had improved survival in comparison with patients receiving systemic therapy alone in propensity score-matched cohorts (2-year overall survival, 34.2% vs 20.6%; P < .001). Improved survival was associated only with patients receiving high-intensity local treatment, whereas those receiving lower-intensity local treatment had survival similar to that of patients receiving systemic therapy without local treatment. The impact of high-intensity local therapy was time-dependent, with a stronger impact within the first 6 months after the diagnosis (adjusted hazard ratio [AHR], 0.255; 95% confidence interval [CI], 0.210-0.309; P < .001) in comparison with more than 6 months after the diagnosis (AHR, 0.622; 95% CI, 0.561-0.689; P < .001) in the multivariate analysis. A benefit was seen in all subgroups, in landmark analyses of 1-, 2-, and 3-year survivors, and when adjusting for the number and location of metastatic sites. Aggressive local treatment warrants prospective evaluation for select patients with metastatic HNSCC. Cancer 2017;123:4583-4593. © 2017 American Cancer

  14. Safety and treatment outcomes of first-line pazopanib in renal cell carcinoma: A prospective observational study in a single Malaysia tertiary hospital

    2017-12-01

    Full Text Available Introduction: Pazopanib is the standard of care for metastatic renal cell carcinoma (mRCC. Previous studies on this indication were limited to patients who were selected on the basis of a fairly preserved performance status and normal organ function. Thus, the clinical trial population may not be representative of all patients seen in real-world practice. Based on these considerations, this prospective single-centre observational study was designed to evaluate the treatment outcomes and safety profile of pazopanib in Malaysian population. Patients and methods: Patients prescribed with pazopanib between June 2015 and June 2017 were recruited and followed up for 2-years or till death whichever comes first. Progression-free survival (PFS and overall survival (OS were evaluated. Multivariate and survival analysis were performed. Results: Twenty-seven patients were treated with pazopanib where 89% had clear cell histology.  Sixteen patients (59% were intermediate risk and 41% were poor risk based on Memorial Sloan Kettering Cancer Center (MSKCC criteria. All patients experienced at least one adverse event. The most common were cutaneous toxicity (92% followed by proteinuria, hypertension, diarrhoea and mucositis. Treatment interruption was needed in 15 patients. The median PFS and OS were 9.57 months and 15.5 months, respectively. In multivariate analysis, MSKCC risk score demonstrates strong predictive treatment outcome. The median PFS was 14.5 months in intermediate risk and 3.96 months in poor risk (OR: 0.2, p<0.001. However, the median OS is still immature to be reported since 63% of intermediate risk group is still alive at 2-years follow-up. Conclusion: In mRCC patients, treatment with pazopanib was effective in patients with intermediate risk group. In terms of safety, patient tolerated pazopanib quite well with mostly experienced grade 1 to 2 adverse events.

    Metastasis from basal cell carcinoma of the skin is very rare with cases being documented in the lymph nodes, lung, bone and parotid gland. The main histopathological differential diagnosis is the locally arising basal cell adenocarcinoma from which it is difficult to distinguish by morphology and routine immunohistochemistry. Approximately 85 % of all reported metastatic basal cell carcinomas arise in the head and neck region. Here we present a case of basal cell carcinoma of the skin of the left lateral canthus of the eye which metastasized to the intraparotid lymph nodes with infiltration of the adjacent parotid parenchyma. More awareness and vigilance is required on the part of the reporting pathologist to consider metastasis in the presence of a parotid tumour. Features favouring metastasis include history of primary cutaneous basal cell carcinoma, histological similarity to the primary lesion and absence of any demonstrable direct extension from the skin lesion. We also review the literature on metastatic basal cell carcinoma and discuss the need for adequate follow up in high risk patients.

    Labial mucosa is an atypical site of basal cell carcinoma. The involvement of the vermilion lip, devoid of hair follicles and sweat glands, contrasts with the concept of its origin from pilar structures. We report a case of basal cell carcinoma developed on the vermilion upper lip. A 49-year-old woman, presented with an asymptomatic, 1-cm-diameter, erythematous, telangiectatic and crusted nodule on the upper lip evolving for 9 months and having once interested the vermilion border. There were no cervical lymph nodes. Diagnosis of infiltrative basal cell carcinoma was made by histological study, which showed a tumoral proliferation of epithelial basal cells infiltrating the dermis with perineural and muscular infiltration. Our report illustrates a rare but not exceptional site of basal cell carcinoma. The nodule, initially confined to the vermilion border, has then developed onto the mucosal and the cutaneous areas. Histopathological study revealed, as previously reported, infiltarative features. Basal cell carcinoma of the lip should be rapidly managed since its invasion to deeper structures occurs early.

    Merkel cell carcinoma is a rare lymphophilic skin tumor of neuroendocrine origin with the potential for rapid progression. Small, localized lesions are diagnosed and treated clinically, but advanced tumors often undergo imaging evaluation. Due to its rarity, radiologists are unaware of evocative imaging features and usually do not consider Merkel cell carcinoma in the differential diagnosis of soft tissue tumors. Appropriate staging is important to determine appropriate treatment and has an impact on patient prognosis. Multimodality imaging is usually needed, and there is no consensus on the optimal imaging strategy. The purpose of this article is to review various aspects of Merkel cell carcinoma imaging and look in detail at how optimal multimodality staging should be carried out. (orig.)

    Full Text Available Nonmelanoma skin cancers (NMSCs, which include basal and squamous cell cancers are the most common human cancers. BCCs have a relatively low metastatic rate and slow growth and are frequently underreported. Whilst there is a definite role of sunexposure in the pathogenesis of BCC, several additional complex genotypic, phenotypic and environmental factors are contributory. The high prevalence and the frequent occurrence of multiple primary BCC in affected individuals make them an important public health problem. This has led to a substantial increase in search for newer noninvasive treatments for BCC. Surgical excision with predetermined margins remains the mainstay treatment for most BCC. Of the newer non-invasive treatments only photodynamic therapy and topical imiquimod have become established in the treatment of certain BCC subtypes, while the search for other more effective and tissue salvaging therapies continues. This paper focuses on the pathogenesis and management of BCC.

    To analyze the accuracy of the Tzanck smear test (TST) for margin control in surgery for well-demarcated basal cell carcinoma (BCC). Twenty-one patients with well-demarcated BCC were included in this study. After local anesthesia, the tumors were excised. The pathologist examined the frozen sections. If the tumor cells were observed in the margin, a re-excision was done. This procedure was repeated until the margin was tumor free. After each excision, Tzanck smear samples were taken from the defect area. The samples obtained were stained with May-Grünwald-Giemsa and examined. The accuracy of TST was then analyzed by comparison of the TST results with those of frozen section examination. The sensitivity and specificity of TST for margin assessment were 1.00 (95% confidence interval (CI)=1.00-1.00) and 0.99 (95% CI=0.98-1.00), respectively. Positive and negative predictive values and the diagnostic accuracy for TST were 0.94 (95% CI=0.84-1.05), 1.00 (95% CI=1.00-1.00), and 1.00 (95% CI=0.99-1.00), respectively. No recurrences were observed in the average 2-year follow-up period. The high accuracy of TST for margin control is encouraging to develop a practical alternative approach for the treatment of well-demarcated BCC.

    To evaluate the detectability of the residual tumour in post-treatment granulation tissue using parameters obtained with an advanced diffusion model in patients with head and neck squamous cell carcinoma (HNSCC) treated by chemoradiation therapy. We retrospectively evaluated 23 patients with HNSCC after the full course of chemoradiation therapy. The diffusion-weighted image (DWI) acquisition used single-shot spin-echo echo-planar imaging with 11 b-values (0-1000). We calculated 10 DWI parameters using a mono-exponential model, a bi-exponential model, a stretched exponential model (SEM), a diffusion kurtosis imaging (DKI) model and a statistical diffusion model (SDM) in the region of interest (ROI) placed on the post-treatment granulation tissue. The presence of residual tumour was determined by histological findings or clinical follow-up. Among the 23 patients, seven patients were revealed to have residual tumour. The univariate analysis revealed significant differences in six parameters between the patients with and without residual tumour. From the receiver operating characteristic curve analysis, the highest area under curve was detected in the center of the Gaussian distribution of diffusion coefficient (D s ) obtained by the SDM. The multivariate analysis revealed that the D s and diffusion heterogeneity (α) obtained by the SEM were predictors for the presence of residual tumour. DWI parameters obtained by advanced fitting models will be one of the diagnostic tools for the detection of residual tumour. Copyright © 2017 Elsevier B.V. All rights reserved.

    Pyropheophorbide-a-hexyl ether (HPPH) is a new photosensitizer for use with photodynamic therapy (PDT) that has shown promise in laboratory animals. PDT, using this drug, is being used to treat canine patients afflicted with hemangiopericytoma and oral squamous cell carcinoma (SCC) at the University of Missouri-Columbia College of Veterinary Medicine. To date, 11 dogs with hemangiopericytoma and 5 dogs with oral SCC have been treated using a combination of surgery and PDT. Thus far, there have been no serious complications attributable to the treatment. Two dogs have had recurrences of the hemangiopericytoma and there have been no recurrences of SCC with a median follow time of 5 months. Both recurrent hemangiopericytomas were in patients with large tumors that had previous surgery. This study is ongoing and no conclusions have been reached; however several observations are noted. It appears that PDT using HPPH is safe is dogs, and may decrease the recurrence rate of Hemangiopericytomas. In dogs with oral SCC, the treatment is effective is causing necrosis and sloughing of the tumor tissue, and recurrences have not been noted on follow-ups up to 6 months.

    Isodeoxyelephantopin (IDOE) isolated from Elephantopus scaber L. (Didancao) is used in Chinese medicine for the treatment of some types of cancer. The anti-cancer mechanism of IDOE remains unclear. This study aims to investigate the antiproliferative activity of IDOE on breast carcinoma T47D cells and lung carcinoma A549 cells. The growth inhibitory effects of IDOE on breast carcinoma T47D cells, lung carcinoma A549 cells, and normal lymphocytes were evaluated by the MTT assay. Morphological analysis of apoptosis induction was performed by acridine orange/ethidium bromide dual-staining and Hoechst 33342 nuclear staining. The cell cycle profile, caspase-3 expression, and annexin V staining were evaluated by flow cytometry. IDOE inhibited the growth of A549 and T47D cells in a dose- and time-dependent manner with IC50 values of 10.46 and 1.3 μg/mL, respectively. IDOE was not significantly toxic to normal lymphocytes. The cells became detached from the monolayer and rounded up, had fragmented nuclei and condensed chromatin, and the numbers of apoptotic cells increased (P = 0.0003). IDOE-induced cell death was associated with activated caspase-3 expression followed by cell cycle arrest at G2/M phase. IDOE inhibited the proliferation of breast cancer cells and lung carcinoma cells and induced caspase-3-mediated apoptosis and cell cycle arrest in the treated cells.

    Urethral carcinoma in women is uncommon. This study was undertaken to evaluate the role of radiotherapy in the treatment of these tumors. The hospital records of 34 women with primary urethral carcinoma were retrospectively reviewed. There were 15 squamous cell carcinomas, 13 transitional cell carcinomas, and six adenocarcinomas. The primary tumor was >4 cm in size in eight patients, involved the proximal urethra in 19 and extended to adjacent organs in 22. Inguinal or iliac lymphadenopathy was present in nine patients. There were eight TNM stage I/II tumors, 11 stage III tumors and 15 stage IV tumors. Radiotherapy was administered only to the primary tumor in 15 patients, and to the primary tumor and regional lymph nodes in the remaining 19 patients. Brachytherapy with or without external radiation was used to treat the primary tumor in 20 patients. Tumor recurred in 21 patients. The 7-year actuarial overall and cause-specific survivals were 41 and 45%, respectively. Large primary tumor bulk and treatment with external beam radiation alone (no brachytherapy) were independent adverse prognostic factors for local tumor recurrence. Brachytherapy reduced the risk of local recurrence by a factor of 4.2. The beneficial effect of brachytherapy was most prominently seen in patients with bulky primary disease. Large tumor size was the only independent adverse predictor of overall disease recurrence and death from cancer. Radiotherapy is an effective treatment for carcinoma of the female urethra and preserves normal anatomy and function. Brachytherapy improves local tumor control, possibly as a result of the higher radiation dose that can safely be delivered. (author)

    It is generally believed that patients with Hürthle cell thyroid carcinoma (HCTC) have a poor prognosis. Furthermore, distant metastases represent the most frequent cause of thyroid cancer-related death of patients with HCTC. The aim of this study was to report the treatment and outcomes of patients with distant metastases. Altogether 108 patients were treated for HCTC from 1972 to 2011 in our tertiary center and 32 patients (19 females, 13 males; median age 64.5 years) had either initially proven metastatic disease (N = 12) or distant progression of HCTC after initial treatment (N = 20). Patients with metastases were followed for 1–226 (median 77) months. Data were collected on the patients’ gender and age, extent of their disease, morphologic characteristics, therapy, outcome, and survival rate. Statistical correlation between possible prognostic factors and cause-specific survival from time of detection of metastases was analyzed by univariate analysis and log-rank test. The most common were lung metastases, followed by bone, mediastinum, kidney, and liver in 24, 8, 2, 1, and 1 case, respectively. Total thyroidectomy, lobectomy, subtotal thyroidectomy and neck dissection were performed in 19, 10, 3, and 7 patients, respectively. Radioiodine (RAI) ablation of thyroid remnant was performed in 30 patients, while 20 of them had RAI therapy (median 4 times). RAI uptake in metastases was present in 16 patients and ranged from 0.05 % to 12 %. Chemotherapy was used in 13 patients and external beam radiotherapy in 19 patients. Locoregional control of disease was achieved in 19/21 (90 %) cases who succumbed due to HCTC. Estimated 10-year disease-specific survival for all patients was 60 %. 10-year disease-specific survival for patients with pulmonary metastases and other sites metastases was 60 % and 62 %, respectively. 10-year disease-specific survival for patients with single organ and multiple organ metastases was 52 %, and 100 %, respectively.

    Full Text Available So-called shadow cell differentiation (SCD is typical for pilomatrixoma and other skin lesions with follicular differentiation, but it was rarely described also in some visceral carcinomas. We report a case of ovarian basaloid carcinoma with SCD. The tumor presented as a 14 cm ovarian mass in a 45-year-old woman, and therefore the adnexectomy and hysterectomy were performed. The tumor was of high stage. Multiple metastases were found in the liver, retroperitoneal and mediastinal lymph nodes, and the lung. Histologically, the tumor showed a pattern of high-grade basaloid carcinoma with numerous shadow cells. Extensive histologic examination did not reveal any glandular or preexisting teratoma component. Immunohistochemically, the tumor expressed markers of squamous cell differentiation, such as p63, cytokeratin 5/6, and high-molecular-weight keratin. Cytokeratin 7 and CA125 were positive in scattered cells of the lesion. Estrogen and progesterone receptor, vimentin, and p53 were negative. Beta-catenin showed nuclear and cytoplasmic positivity, indicating possible tumor proliferation/differentiation via Wnt signaling pathway. To our knowledge, SCD in basaloid carcinoma of the ovary was not described before. In addition to the description of the case, we review the literature on SCD in visceral carcinomas.

    The employment of surgery as a single treatment modality for patients with resectable locally advanced head and neck squamous cell carcinoma (HNSCC) has been associated with high rates of locoregional recurrences even after adequate resection. The addition of postoperative radiotherapy (RT) as adjuvant to surgical resection for advanced HNSCC was investigated in an effort to decrease locoregional failure rates and improve treatment outcome. The unsatisfactory results in terms of locoregional control (LRC) and survival rates achieved with postoperative RT in patients with high-risk features have led to the necessity of exploring the role of concurrent chemotherapy in the adjuvant treatment in resectable advanced HNSCC with confirmed presence of high-risk pathological features. Two prospective randomized independent trials designed and conducted by Radiation Therapy Oncology Group (RTOG) and the European Organization for Research and Treatment of Cancer (EORTC) demonstrated that the addition of cisplatin-based chemotherapy improved LRC and disease-free survival (DFS). Significant improvement in overall survival (OS) with the use of postoperative concurrent chemoradiotherapy (CCRT) was observed in the EORTC trial. High-risk pathological features in patients with resected head and neck cancer representing adverse prognostic factors that are predictive for local and/or regional recurrence are related to the primary tumor and/or metastatic lymph nodes in the neck. Extracapsular extension (ECE) of nodal disease in the neck has been confirmed as a high-risk pathological feature negatively influencing LRC and survival in patients treated with either postoperative RT or postoperative CCRT. This article reviews the historical progress in the management of resectable locally advanced HNSCC and the impact of ECE on clinical outcome in patients treated with adjuvant therapy following surgery. It can be concluded that strong evidence exists for an improved outcome for high

    Despite laparoscopic partial nephrectomy and laparoscopic cryotherapy being performed lately, an even less invasive treatment would be desirable in high-risk patients. Under local anesthesia with intravenous (i.v.) sedation, we were able to perform percutaneous radiofrequency ablation (RFA) combined with renal arterial embolization for unresectable stage 1 (T1NoMo) renal cell carcinoma (RCC). We evaluated the feasibility, safety and therapeutic effects of this technique after a 2-year mean follow up. Thirty-one patients who were not candidates for surgery underwent RFA for 36 stage 1 RCC. Twenty-eight tumors were percutaneously ablated 6 days after the tumor vessels were embolized. Dynamic contrast-enhanced computed tomography (CT) and magnetic resonance imaging (MRI) were performed to evaluate treatment at completion. Tumor enhancement was eliminated after two RFA sessions in all tumors. Thirty tumors remained free of enhancement during a mean follow-up period of 24.3 months. There were no major complications related to the procedures though one instance of pyonephrosis, two of subcapsular hematomas, one of retroperitoneal hemorrhage and one of nausea were seen after RFA. Two patients died of other diseases (id est (i.e.) colon cancer and cerebral bleeding) 20 and 26 months after RFA treatment. One patient had a local recurrence of tumor and underwent re-RFA. The recurrence rate of RCC after successful RFA was 2.8%. There was no recurrence in patients who had tumors of less than 4 cm after RFA at a mean follow-up period of 24.3 months. Local control was achieved in 100% of T1NoMo tumors including the recurrence case that underwent re-RFA. The result of the present study at 2-year mean follow up showed percutaneous RFA was a feasible, safe and promising therapy for the treatment of unresectable stage 1 RCC, especially those smaller than 4 cm.

    Breast cancer is the most common type of cancer, predominantly among women over 20, whereas colo-rectal cancer occurs in both men and women over the age of 50. Chemotherapy of both cancers affect rapidly growing normal as well as cancer cells. Cancer cells are non-apoptotic. Seven anti-cancer agents (cis -platin, Tamoxifen, Melphalan, Betulinic acid, D-PDMP, L-PPMP, and GD3) have been tested with human breast (SKBR3) and colon (Colo-205) carcinoma cells for their apoptotic effect and found to be positive by several assay systems. Colo-205 cells were obtained from ATCC, and the SKBR3 cells were a gift from the Cleveland Clinic. All of these six agents killed those two cell lines in a dose-dependent manner. In the early apoptotic stage (6 h), these cells showed only a flopping of phosphatidylserine on the outer lamella of the plasma membranes as evidenced by the binding of a novel fluorescent dye PSS-380. After 24 h of the treatment, those apoptotic cells showed damage of the plasma as well as the nuclear membrane as evidenced by binding of propidium iodide to the nuclear DNA. DNA laddering assay viewed further breakdown of DNA by 1% agarose gel electrophoresis analysis. It is concluded that during apoptosis the signaling by Mitochondrial Signaling Pathway (MSP) is stimulated by some of these agents. Caspase 3 was activated with the concomitant appearance of its p17 polypeptide as viewed by Westernblot analyses. Incorporation of radioactivity from [U-(14)C]-L-serine in total sphingolipid mixture was observed between 2 and 4 micromolar concentrations of most of the agents except ci s-platin. However, apoptosis in carcinoma cells in the presence of cis -platin is induced by a caspase 3 activation pathway without any increase in synthesis of ceramide.

  1. Renal Preservation Therapy for Renal Cell Carcinoma

    2012-01-01

    Full Text Available Renal preservation therapy has been a promising concept for the treatment of localized renal cell carcinoma (RCC for 20 years. Nowadays partial nephrectomy (PN is well accepted to treat the localized RCC and the oncological control is proved to be the same as the radical nephrectomy (RN. Under the result of well oncological control, minimal invasive method gains more popularity than the open PN, like laparoscopic partial nephrectomy (LPN and robot assisted laparoscopic partial nephrectomy (RPN. On the other hand, thermoablative therapy and cryoablation also play an important role in the renal preservation therapy to improve the patient procedural tolerance. Novel modalities, but limited to small number of patients, include high-intensity ultrasound (HIFU, radiosurgery, microwave therapy (MWT, laser interstitial thermal therapy (LITT, and pulsed cavitational ultrasound (PCU. Although initial results are encouraging, their real clinical roles are still under evaluation. On the other hand, active surveillance (AS has also been advocated by some for patients who are unfit for surgery. It is reasonable to choose the best therapeutic method among varieties of treatment modalities according to patients' age, physical status, and financial aid to maximize the treatment effect among cancer control, patient morbidity, and preservation of renal function.

  2. Idiopathic Radiation Recall Dermatitis Developing Nine Months after Cessation of Cisplatin Therapy in Treatment of Squamous Cell Carcinoma of the Tonsil

    Stephen M. Melnyk

    2012-01-01

    Full Text Available To report on a suspected case of idiopathic radiation recall dermatitis in an individual nine months after radiation and chemotherapy treatment of squamous cell carcinoma of the right tonsil. Radiation recall dermatitis is the development of a reaction in a previously irradiated area of skin after the administration of an aggravating medication. A review of the literature revealed several cases of radiation recall dermatitis that occur following radiation therapy and the institution of chemotherapy. Other medications have also been implicated in radiation recall dermatitis; however, this patient has not started any new medications since completion of his combined therapy. The patient developed this skin reaction in a distribution pattern identical to the area that received the highest radiation dose suggesting a possible link between radiation recall dermatitis and radiation dose. Radiation recall dermatitis is a reaction that is typically seen shortly after the reinstitution of chemotherapy during radiation therapy. This case illustrates that other medical etiologies are possible and suggests a relationship between radiation recall dermatitis and the total radiation dose an area receives.

    Few studies have been published on the safety and feasibility of synchronous use of peptide receptor radionuclide therapy (PRRNT), as source of internal radiation therapy, in combination with chemotherapy. In this study we reported a 53-year-old man with stage IV Merkel cell carcinoma (MCC), who underwent synchronous internal radiation therapy and chemotherapy. Based on presumable poor prognosis with chemotherapy only, functional similarities of MCC with other neuroendocrine tumors and available evidence of effectiveness and safety of synchronous use of external beam radiation therapy and chemotherapy in treatment of high-risk MCC patients, our interdisciplinary neuroendocrine tumor board recommended him to add PRRNT to his ongoing chemotherapy. He received 2 courses of (177)Lu-DOTATATE(1, 4, 7, 10-Tetraazacyclododecane-1, 4, 7, 10-tetraacetic acid-1-D-Phe1-Tyr3-Thr8-octreotide) in combination with ongoing 8 cycles of liposomal doxorubicin based on standard protocols. Response to therapy was evaluated by (18)F-FDG and (68)gallium-somatostatin-receptor PET/CT. There was an impressive improvement of the clinical symptoms. However, follow-up PET/CT studies showed mixed pattern of response. Synchronous use of PRRNT and radiosensitizing chemotherapy seems safe and feasible in high risk MCC patients, however, further prospective studies and clinical trials are warranted to provide reliable evidence of possible pitfalls and effectiveness of PRRNT and (68)Ga-somatostatin-receptor PET/CT in the management of MCC.

    To evaluate the diagnostic value of intravoxel incoherent motion (IVIM) and diffusional kurtosis imaging (DKI) parameters in nasal or sinonasal squamous cell carcinoma (SCC) patients to determine local control/failure. Twenty-eight patients were evaluated. MR acquisition used single-shot spin-echo EPI with 12 b-values. Quantitative parameters (mean value, 25th, 50th and 75th percentiles) of IVIM (perfusion fraction f, pseudo-diffusion coefficient D*, and true-diffusion coefficient D), DKI (kurtosis value K, kurtosis corrected diffusion coefficient D{sub k}) and apparent diffusion coefficient (ADC) were calculated. Parameter values at both the pretreatment and early-treatment period, and the percentage change between these two periods were obtained. Multivariate logistic regression analysis: the percentage changes of D (mean, 25th, 50th, 75th), K (mean, 50th, 75th), Dk (mean, 25th, 50th), and ADC (mean, 25th, 50th) were predictors of local control. ROC curve analysis: the parameter with the highest accuracy = the percentage change of D value with the histogram 25th percentile (0.93 diagnostic accuracy). Multivariate Cox regression analyses: the percentage changes of D (mean, 25th, 50th), K (mean, 50th, 75th), Dk (mean, 25th, 50th) and ADC (mean, 25th, 50th) are predictors. IVIM and DKI parameters, especially the D-value's histogram 25th percentile, are useful for predicting local control. (orig.)

    We report an 83 year-old patient with a 13 × 7.5 cm(2) basal cell carcinoma (BCC) successfully treated with the combination of vismodegib and minimal surgery. On Day 109, a 0.9 cm papule suspicious for residual BCC was seen centrally within a large pink atrophic plaque. This lesion was excised; pathology confirmed BCC with negative surgical margins. Simultaneously, suspecting noncontiguous histologic response, we performed 21 biopsies at the periphery of the pretreatment tumor location. Seventeen (17/21, 81%) revealed lichenoid dermatitis. No tumor was seen on any. We believe the lichenoid dermatitis observed is a novel finding for two reasons. First, it may be considered a marker of a positive intratreatment response. This may help guide clinicians on the optimal treatment duration of vismodegib to maximize efficacy and mitigate side effects. Second, we think it suggests an additional mechanism of vismodegib action, possibly via local immune effects. Further investigations are warranted. © 2015 Wiley Periodicals, Inc.

    Currently, most of renal tumors are small, low grade, with a slow growth rate, a low metastatic potential, and with up to 30 % of these tumors being benign on the final pathology. Moreover, they are often diagnosed in elderly patients with preexisting medical comorbidities in whom the underlying medical conditions may pose a greater risk of death than the small renal mass. Concerns regarding overdiagnosis and overtreatment of patients with indolent small renal tumors have led to an increasing interest in minimally invasive, ablative as an alternative to extirpative interventions for selected patients. To provide an overview about the state of the art in radiofrequency ablation (RFA), high-intensity focused ultrasound, and cryoablation in the clinical management of renal cell carcinoma. A PubMed wide the literature search of was conducted. International consensus panels recommend ablative techniques in patients who are unfit for surgery, who are not considered candidates for or elect against elective surveillance, and who have small renal masses. The most often used techniques are cryoablation and RFA. These ablative techniques offer potentially curative outcomes while conferring several advantages over extirpative surgery, including improved patient procedural tolerance, faster recovery, preservation of renal function, and reduction in the risk of intraoperative and postsurgical complications. While it is likely that outcomes associated with ablative modalities will improve with further advances in technology, their application will expand to more elective indications as longer-term efficacy data become available. Ablative techniques pose a valid treatment option in selected patients.

    The burden of advanced basal cell carcinoma (aBCC) is not fully understood. To compare BCC disease burden and treatment patterns for aBCC with those for non-aBCC. A retrospective, insurance claims-based study design was used. Adults with ≥2 claims associated with a BCC diagnosis (ICD-9-CM 173.x1) separated by ≥30 days on or after October 1, 2011, were classified as aBCC or non-aBCC by using an algorithm based on metastasis diagnosis, radiation therapy use, and medical oncologist/other specialist use. Non-aBCC and aBCC patients were matched 1:1 on the basis of age, sex, and region, and assigned the same index date (date of first qualifying diagnosis or event). Comparisons were made using Wilcoxon signed-rank (continuous variables) and McNemar's (categorical variables) tests. In total, 847 matched aBCC/non-aBCC patient pairs were selected (mean age 75 years; 57% men; locally advanced BCC, n = 826; metastatic BCC, n = 21). During the 12-month study period following the index date, aBCC patients had a significantly higher mean Charlson Comorbidity Index (P = .0023), significantly higher mean numbers of outpatient/dermatologist/medical oncologist visits (all P < .0001), and significantly higher mean total/medical/inpatient/outpatient/BCC treatment costs (all P < .05). This study only included information from a database on commercial insurance and Medicare claims. The algorithm criteria might have restricted patient numbers; data were not fully reflective of targeted therapy era. aBCC patients had a higher disease burden than non-aBCC patients. Cost differences were largely driven by higher BCC treatment costs, specifically radiation therapy. Copyright © 2017 American Academy of Dermatology, Inc. Published by Elsevier Inc.

    Objective: Hypothyroidism is a common complication in patients receiving tyrosine kinase inhibitors. We evaluated the relationship between thyroid size evident on CT and thyroid function in patients with advanced renal cell carcinoma (RCC) receiving tyrosine kinase inhibitors. Materials and methods: Forty-two patients with metastatic RCC receiving tyrosine kinase inhibitors (sorafenib n = 25; sunitinib n = 17) and, followed-up for ≥12 months were eligible. Patients who had ever shown an elevated thyroid-stimulating hormone (TSH) level of >10 mU/l were defined as having “hypothyroidism”. CT scans were performed before, and 3, 6, 9, and 12 months after the start of treatment. The area of the thyroid in the maximum section at each examination was measured and compared with that before treatment. Using repeated-measures ANOVA, differences in thyroid size were compared over time between patients with and without “hypothyroidism”, in relation to the type of drug employed. Results: Twenty-one patients (sorafenib 9, sunitinib 12) developed “hypothyroidism” 95 ± 88 days (range 12–315 days) after the start of treatment. In such patients, the thyroid was reduced in size to 89 ± 16% after 3 months, 81 ± 21% after 6 months, 71 ± 21% after 9 months and 68 ± 21% after 12 months, whereas the patients without “hypothyroidism” maintained a thyroid size of 90 ± 12% even after 12 months (p = 0.0030). Among the patients with “hypothyroidism”, those treated with sunitinib tended to show greater thyroid size reduction than those with sorafenib (59 ± 23% vs. 79 ± 13%, after 12 months). Conclusion: Tyrosine kinase inhibitors cause an apparent thyroid size reduction in patients with “hypothyroidism”.

    - Basal cell carcinoma (BCC) is the most common human malignant neoplasm and is a frequently encountered diagnosis in dermatopathology. Although BCC may be locally destructive, it rarely metastasizes. Many diagnostic entities display morphologic and immunophenotypic overlap with BCC, including nonneoplastic processes, such as follicular induction over dermatofibroma; benign follicular tumors, such as trichoblastoma, trichoepithelioma, or basaloid follicular hamartoma; and malignant tumors, such as sebaceous carcinoma or Merkel cell carcinoma. Thus, misdiagnosis has significant potential to result in overtreatment or undertreatment. - To review key features distinguishing BCC from histologic mimics, including current evidence regarding immunohistochemical markers useful for that distinction. - Review of pertinent literature on BCC immunohistochemistry and differential diagnosis. - In most cases, BCC can be reliably diagnosed by histopathologic features. Immunohistochemistry may provide useful ancillary data in certain cases. Awareness of potential mimics is critical to avoid misdiagnosis and resulting inappropriate management.

    The oncological outcomes of transthoracic esophagectomy (TTE) and definitive chemoradiotherapy (dCRT) as initial treatment in patients with esophageal squamous cell carcinoma (ESCC) who could tolerate TTE remains unclear. Consecutive patients histologically diagnosed with stage I/II/III ESCC (excluding cT4 or cN3) or stage IV ESCC due to supraclavicular lymph node metastasis were eligible for inclusion in this retrospective study. To select patients who could tolerate TTE, respiratory function, Eastern Cooperative Oncology Group performance status, and preoperative complications were considered. Patient characteristics, recurrence-free survival (RFS), 3- and 5-year overall survival (OS), pattern of recurrence, and treatments after initial treatment failure were investigated. Overall, 112 patients were included in the TTE group and 65 were included in the dCRT group. No significant differences were observed in patient characteristics and clinical stage between the TTE and dCRT groups (stage I/II/III/IV of 29/27/46/10 in the TTE group and 23/15/20/7 in the dCRT group). The R0 resection rate was 87 % in the TTE group, and complete response rate was 68 % in the dCRT group. In intention-to-treat analysis, there was no significant difference in RFS. In contrast, 3-year OS of non-stage IA patients was significantly longer in the TTE group than the dCRT group (TTE 66.9 %; dCRT 49.8 %; p = 0.023). In non-stage IA patients, after initial treatment failure significantly more patients could undergo local treatment (radiotherapy or surgery in the TTE group; surgery or endoscopic resection or photodynamic therapy in the dCRT group) in the TTE group than the dCRT group (TTE 74 %; dCRT 40 %; p = 0.003). In locally advanced ESCC patients who could tolerate TTE, TTE extended 3-year OS, which might have been encouraged by utilizing local treatment after initial treatment failure.

    Primary small cell esophageal carcinoma (SCEC) is a rare and aggressive disease for which there is no recommended standard treatment at this time. A total of 126 patients with SCEC, diagnosed histologically between May 1985 and June 2005 at our institution, were analyzed retrospectively. All were staged according to the Veterans' Administration Lung Study Group staging system. The TNM system for esophageal carcinoma (6th edition, American Joint Committee on Cancer) was also used for those who underwent esophagectomies. SPSS (10.0) software was used for statistical analysis. Cox's hazard regression model was performed to identify prognostic factors. The Kaplan-Meier and log-rank methods were used to estimate and compare survival rates. The chi2 test was performed to examine frequencies between different groups. Through a median follow-up of 13 months, 108 patients died, 10 were alive, and 8 were lost to follow-up. Of the entire study population, the overall median survival time (MST) and 1-, 3-, and 5-year overall survival rates were 12.5 months and 52.2%, 15.9%, and 12.2%, respectively. For limited disease, the MST and 1-, 2-, and 3-year overall survival rates were 14.0 months and 62.1%, 30.8%, and 22.4%, respectively; for extensive disease, the respective values were 7.0 months and 29.3%, 13.6%, and 2.7% (p = 0.0001). The MST of 14.5 months for cases who received chemotherapy was superior to that of 5.2 months for cases who did not (p = 0.0001). Tumor stage, length of the primary lesion, and chemotherapy, but not surgery were independent prognostic factors in a multivariate analysis. SCEC is systemic disease. Tumor stage and chemotherapy were independent prognostic factors. Systemic therapy, based on chemotherapy with radiotherapy, is recommended.

  12. Cathepsin B trafficking in thyroid carcinoma cells

    Full Text Available Abstract Background The cysteine peptidase cathepsin B is important in thyroid physiology by being involved in prohormone processing initiated in the follicle lumen and completed in endo-lysosomal compartments. However, cathepsin B has also been localized to the extrafollicular space in thyroid cancer tissue, and is therefore suggested to promote invasiveness and metastasis in thyroid carcinomas through e.g. extracellular matrix degradation. Methods Transport of cathepsin B in normal thyroid epithelial and carcinoma cells was investigated through immunolocalization of endogenous cathepsin B in combination with probing protease activity. Transport analyses of cathepsin B-eGFP and its active-site mutant counterpart cathepsin B-C29A-eGFP were used to test whether intrinsic sequences of a protease influence its trafficking. Results Our approach employing activity based probes, which distinguish between active and inactive cysteine proteases, demonstrated that both eGFP-tagged normal and active-site mutated cathepsin B chimeras reached the endo-lysosomal compartments of thyroid epithelial cells, thereby ruling out alterations of sorting signals by mutagenesis of the active-site cysteine. Analysis of chimeric protein trafficking further showed that GFP-tagged cathepsin B was transported to the expected compartments, i.e. endoplasmic reticulum, Golgi apparatus and endo-lysosomes of normal and thyroid carcinoma cell lines. However, the active-site mutated cathepsin B chimera was mostly retained in the endoplasmic reticulum and Golgi of KTC-1 and HTh7 cells. Hence the latter, as the least polarized of the three carcinoma cell lines analyzed, exhibited severe transport defects in that it retained chimeras in pre-endolysosomal compartments. Furthermore, secretion of endogenous cathepsin B and of other cysteine peptidases, which occurs at the apical pole of normal thyroid epithelial cells, was most prominent and occurred in a non-directed fashion in thyroid

Radiotherapy is the primary treatment modality. The role of systemic therapy has become more prominent. Based on multiple phase III studies and meta-analyses, concurrent cisplatin-based chemoradiotherapy is the current standard of care for locally advanced disease (American Joint Committee on Cancer manual [7th edition] stages II–IVb. The reported failure-free survival rates from phase II trials are encouraging for induction + concurrent chemoradiotherapy. Data from ongoing phase III trials comparing induction + concurrent chemoradiotherapy with concurrent chemoradiotherapy will validate the results of these phase II studies. Intensity-modulated radiotherapy techniques are recommended if the resources are available. Locoregional control exceeding 90% and reduced xerostomia-related toxicities can now be achieved using intensity-modulated radiotherapy, although distant control remains the most pressing research problem. The promising results of targeted therapy and Epstein–Barr virus-specific immunotherapy from early clinical trials should be validated in phase III clinical trials. New technology, more effective and less toxic chemotherapy regimens, and targeted therapy offer new opportunities for treating nasopharyngeal carcinoma.Keywords: nasopharyngeal carcinoma, intensity-modulated radiotherapy, chemoradiotherapy, molecular targeted agents, immunotherapy, prognostic markers

    Full Text Available Cutaneous squamous cell carcinoma of the head and neck is an epidemic that reaches all parts of the world. Making the diagnosis relies on the acumen of the clinician and pathologist. Various pathologic subtypes exist and differ in histology and prognosis. High-risk tumors need aggressive treatment and vigilant surveillance to monitor for recurrence. Large tumors, deep tissue invasion, perineural involvement, recurrence, location in high-risk areas, and immunosuppression are implicated in worsening prognosis. Surgery is the mainstay of treatment with adjuvant radiation therapy as needed for aggressive tumors; however, other modalities are potentially useful for low-risk lesions. The use of Mohs surgery has become increasingly useful and has shown high success rates. Involvement of parotid and neck lymph nodes significantly affects outcomes and the physician should be comfortable with management of this complex disease. This paper examines the diagnosis, pathology, clinical course, and treatment options for cutaneous squamous cell carcinoma of the head and neck.

    Basal cell carcinoma (BCC) is the most common malignancy worldwide, arising from non-keratinizing cells within the basal layer of the epidermis. The incidence of BCC continues to rise annually, increasing the burden of management of these carcinomas and the morbidity associated with their treatment. While surgical interventions such as Mohs micrographic surgery and surgical excision are the standard of care and yield the highest cure rates, the number of non-surgical interventions approved for the treatment of BCC continues to expand. We review various surgical and non-surgical approaches to the treatment of BCC, focusing on targeted molecular therapies that are approved for locally advanced or recurrent disease. PMID:29259776

    Full Text Available INTRODUCTION: Oral Myiasis, a condition of infestation of the body by fly larvae (maggots is a rare pathology in humans. It is associated with poor oral hygiene, alcoholism, senility, suppurating lesions, severe halitosis. It is seen frequently in tropical countries and hot climatic regions. The reported cases in literature of oral Myiasis associated with oral cancer are few. The treatment is a mechanical removal of the maggots but a systemic treatment with Ivermectin, a semi - synthetic macrolide antibiotic, has been used successfully for treatment for oral m yiasis. We present a case of 55 yr old male alcoholic patient with oral myiasis with extensive proliferative growth of oral cavity. Our patient was managed with manual debridement and administration of systemic ivermect in along with antibiotic coverage. Incisional biopsy of the proliferative lesion showed well differentiated squamous cell carcinoma. Thus our patient showed presence of oral myiasis in association with oral squamous cell carcinoma.

    Introduction. Basal cell carcinoma (BCC) is a locally invasive malignant epidermal tumour. Incidence is increasing by 10% per year; incidence of metastases is minimal, but relapses are frequent (40%-50%). The complete excision of the BCC allows reduction of relapse. Materials and Methods. The study cohort consists of 1123 patients underwent surgery for basal cell carcinoma between 1999 and 2009. Patient and tumor characteristics recorded are: age; gender; localization (head and neck, trunk, and upper and lower extremities), tumor size, excisional margins adopted, and relapses. Results. The study considered a group of 1123 patients affected by basal cell carcinoma. Relapses occurred in 30 cases (2,67%), 27 out of 30 relapses occurred in noble areas, where peripheral margin was <3mm. Incompletely excised basal cell carcinoma occurred in 21 patients (1,87%) and were treated with an additional excision. Discussion. Although guidelines indicate 3mm peripheral margin of excision in BCC <2cm, in our experience, a margin of less than 5mm results in a high risk of incomplete excisions

    Background Accurate detection and analysis of circulating tumor cells plays an important role in the diagnosis and treatment of metastatic cancer treatment. Methods and Findings A cell microarray chip was used to detect spiked carcinoma cells among leukocytes. The chip, with 20,944 microchambers (105 µm width and 50 µm depth), was made from polystyrene; and the formation of monolayers of leukocytes in the microchambers was observed. Cultured human T lymphoblastoid leukemia (CCRF-CEM) cells were used to examine the potential of the cell microarray chip for the detection of spiked carcinoma cells. A T lymphoblastoid leukemia suspension was dispersed on the chip surface, followed by 15 min standing to allow the leukocytes to settle down into the microchambers. Approximately 29 leukocytes were found in each microchamber when about 600,000 leukocytes in total were dispersed onto a cell microarray chip. Similarly, when leukocytes isolated from human whole blood were used, approximately 89 leukocytes entered each microchamber when about 1,800,000 leukocytes in total were placed onto the cell microarray chip. After washing the chip surface, PE-labeled anti-cytokeratin monoclonal antibody and APC-labeled anti-CD326 (EpCAM) monoclonal antibody solution were dispersed onto the chip surface and allowed to react for 15 min; and then a microarray scanner was employed to detect any fluorescence-positive cells within 20 min. In the experiments using spiked carcinoma cells (NCI-H1650, 0.01 to 0.0001%), accurate detection of carcinoma cells was achieved with PE-labeled anti-cytokeratin monoclonal antibody. Furthermore, verification of carcinoma cells in the microchambers was performed by double staining with the above monoclonal antibodies. Conclusion The potential application of the cell microarray chip for the detection of CTCs was shown, thus demonstrating accurate detection by double staining for cytokeratin and EpCAM at the single carcinoma cell level.

After washing the chip surface, PE-labeled anti-cytokeratin monoclonal antibody and APC-labeled anti-CD326 (EpCAM monoclonal antibody solution were dispersed onto the chip surface and allowed to react for 15 min; and then a microarray scanner was employed to detect any fluorescence-positive cells within 20 min. In the experiments using spiked carcinoma cells (NCI-H1650, 0.01 to 0.0001%, accurate detection of carcinoma cells was achieved with PE-labeled anti-cytokeratin monoclonal antibody. Furthermore, verification of carcinoma cells in the microchambers was performed by double staining with the above monoclonal antibodies. CONCLUSION: The potential application of the cell microarray chip for the detection of CTCs was shown, thus demonstrating accurate detection by double staining for cytokeratin and EpCAM at the single carcinoma cell level.

    Ultraviolet B (UVB) light is the major environmental carcinogen contributing to non-melanoma skin cancer (NMSC) development. There are over 3.5 million NMSC diagnoses in two million patients annually, with men having a 3-fold greater incidence of squamous cell carcinoma (SCC) compared with women. Chronic inflammation has been linked to tumorigenesis, with a key role for the cyclooxygenase-2 (COX-2) enzyme. Diclofenac, a COX-2 inhibitor and non-steroidal anti-inflammatory drug, currently is prescribed to patients as a short-term therapeutic agent to induce SCC precursor lesion regression. However, its efficacy as a preventative agent in patients without evidence of precursor lesions but with significant UVB-induced cutaneous damage has not been explored. We previously demonstrated in a murine model of UVB-induced skin carcinogenesis that when exposed to equivalent UVB doses, male mice had lower levels of inflammation but developed increased tumor multiplicity, burden and grade compared with female mice. Because of the discrepancy in the degree of inflammation between male and female skin, we sought to determine if topical treatment of previously damaged skin with an anti-inflammatory COX-2 inhibitor would decrease tumor burden and if it would be equally effective in the sexes. Our results demonstrated that despite observed sex differences in the inflammatory response, prolonged topical diclofenac treatment of chronically UVB-damaged skin effectively reduced tumor multiplicity in both sexes. Unexpectedly, tumor burden was significantly decreased only in male mice. Our data suggest a new therapeutic use for currently available topical diclofenac as a preventative intervention for patients predisposed to cutaneous SCC development before lesions appear.

    Purpose: This study was designed to assess the 3-year experience with superselective intraarterial chemotherapy prior to definitive treatment for stages III and IV squamous cell carcinomas of the mouth. Methods: Twenty-two patients prospectively received superselective intraarterial chemotherapy using relatively low-dose cisplatin via a transfemoral approach. The locations of the tumors were the tongue (n= 12), gingiva (n= 5), buccal mucosa (n= 2), hard palate (n= 1), floor of the mouth (n= 1), and lip (n= 1). After intraarterial chemotherapy, 21 patients underwent surgery (n= 14), radiation therapy (n= 6), or both (n= 1). The survival rate of 25 patients who underwent surgery with/without radiation therapy until 1992 at Kumamoto University Hospital was also evaluated as a historical control. The survival curve was calculated with the Kaplan-Meier method, and the statistical difference between survival curves was determined with the generalized Wilcoxon test. Results: The overall response rate was 95% [complete response (tumor completely resolved), 24%; partial response (tumor reduction ≥50%), 71%]. Fifty-two intraarterial infusions were performed without any catheter-related complications. Mild and transient local toxicity such as edema or mucositis of the infused area was relatively common. One patient died of renal failure from cisplatin. After a median follow-up of 20 months (range 2-41 months), the estimated 3-year survival rate for patients who underwent intraarterial chemotherapy plus surgery was 91%. The survival of the patients who underwent intraarterial chemotherapy plus surgery tended to be longer than that of the historical control. Conclusions: Early tumor reduction without delay of subsequent treatments can be obtained by intraarterial chemotherapy while minimizing complications and possibly improving survival. Further investigations of long-term survival with larger series need to be performed

    Full Text Available EBV-related nasopharyngeal carcinomas (NPCs still raise serious therapeutic problems. The therapeutic potential of the histone-deacetylase (HDAC inhibitor Abexinostat was investigated using 5 preclinical NPC models including 2 patient-derived xenografts (C15 and C17. The cytotoxicity of Abexinostat used either alone or in combination with cis-platin or irradiation was assessed in vitro by MTT and clonogenic assays using 2 EBV-negative (CNE1 and HONE1 and 3 EBV-positive NPC models (C15, C17 and C666-1. Subsequently, the 3 EBV-positive models were used under the form of xenografts to assess the impact of systemic treatments by Abexinostat or combinations of Abexinostat with cis-platin or irradiation. Several cell proteins known to be affected by HDAC inhibitors and the small viral non-coding RNA EBER1 were investigated in the treated tumors. Synergistic cytotoxic effects of Abexinostat combined with cis-platin or irradiation were demonstrated in vitro for each NPC model. When using xenografts, Abexinostat by itself (12.5 mg/kg, BID, 4 days a week for 3 weeks had significant anti-tumor effects against C17. Cooperative effects with cis-platin (2 mg/kg, IP, at days 3, 10 and 17 and irradiation (1 Gy were observed for the C15 and C17 xenografts. Simultaneously two types of biological alterations were induced in the tumor tissue, especially in the C17 model: a depletion of the DNA-repair protein RAD51 and a stronger in situ detection of the small viral RNA EBER1. Overall, these results support implementation of phase I/II clinical trials of Abexinostat for the treatment of NPC. A depletion of RAD51 is likely to contribute to the cooperation of Abexinostat with DNA damaging agents. Reduction of RAD51 combined to enhanced detection of EBER 1 might be helpful for early assessment of tumor response.

    Adrenocortical carcinoma is a rare neoplasm characterized by a high risk of recurrence after radical resection. Whether the use of mitotane is beneficial as an adjuvant treatment has been controversial. Our aim was to evaluate the efficacy of adjuvant mitotane in prolonging recurrence-free survival. We performed a retrospective analysis involving 177 patients with adrenocortical cancer who had undergone radical surgery at 8 centers in Italy and 47 centers in Germany between 1985 and 2005. Adjuvant mitotane was administered to 47 Italian patients after radical surgery (mitotane group), whereas 55 Italian patients and 75 German patients (control groups 1 and 2, respectively) did not receive adjuvant treatment after surgery. Baseline features in the mitotane group and the control group from Italy were similar; the German patients were significantly older (P=0.03) and had more stage I or II adrenocortical carcinomas (P=0.02) than did patients in the mitotane group. Recurrence-free survival was significantly prolonged in the mitotane group, as compared with the two control groups (median recurrence-free survival, 42 months, as compared with 10 months in control group 1 and 25 months in control group 2). Hazard ratios for recurrence were 2.91 (95% confidence interval [CI], 1.77 to 4.78; P<0.001) and 1.97 (95% CI, 1.21 to 3.20; P=0.005), respectively. Multivariate analysis indicated that mitotane treatment had a significant advantage for recurrence-free survival. Adverse events associated with mitotane were mainly of grade 1 or 2, but temporary dose reduction was needed in 13% of patients. Adjuvant mitotane may prolong recurrence-free survival in patients with radically resected adrenocortical carcinoma. Copyright 2007 Massachusetts Medical Society.

    Purpose Hand-foot syndrome is a common dose limiting toxicity of vascular endothelial growth factor receptor tyrosine kinase inhibitors used for treatment of patients with metastatic renal cell carcinoma. The effect of treatment dose reductions, in the context of hand-foot syndrome, on survival outcomes is reported. Methods This was a retrospective case series of patients receiving vascular endothelial growth factor receptor tyrosine kinase inhibitors from 1 January 2004 to 31 October 2013. The main outcomes were progression-free and overall survival in these patients experiencing hand-foot syndrome and undergoing treatment dose reductions. Univariate and multivariate analyses were conducted utilizing Kaplan-Meier method and COX Proportional Hazard model with landmark analyses at 2 months. Results Of the 120 patients evaluated, treatment dose reductions for any reason were required in 68 (56.7%) patients. The most common reasons for treatment dose reductions were mucositis, hand-foot syndrome, and fatigue. The median progression-free survival and overall survival were significantly longer in patients with hand-foot syndrome with or without treatment dose reductions as compared to those without hand-foot syndrome. Conclusions An improvement in survival outcomes was observed in metastatic renal cell carcinoma patients with treatment-associated hand-foot syndrome despite treatment dose reductions. These data need validation in a larger cohort to confirm the hypothesis that treatment dose reductions in the setting of hand-foot syndrome do not negatively impatient survival.

    Interaction between tumour survival tactics and anti-tumour immune response is a major determinant for cancer growth. Regulatory T cells (T-regs) contribute to tumour immune escape, but their role in basal cell carcinoma (BCC) is not understood. The fraction of T-regs among T cells was analysed...... by immunohistochemistry followed by automated image analysis in facial BCC, peritumoural skin and normal, buttock skin. Quantitative real-time PCR (qRT-PCR) was performed for FOXP3 and cytokines involved in T-reg attraction and T-cell activation. T-regs comprised 45% of CD4-cells surrounding BCC. FOXP3 was highly...

    Lung adenosquamous carcinoma (ASC) is a rare malignant tumor with an adenocarcinoma and a squamous cell carcinoma component and associated with a lower 5-year survival rate than lung squamous cell carcinoma and lung adenocarcinoma. Surgical specimen histology revealed the inadequacy of conventional transbronchial needle aspiration samples in the diagnosis of lung ASC. Most lung ASC patients are not suitable to receive surgery, and it is difficult to diagnose ASC. This study is to explore the possibility of using serum carcinoembryonic antigen (CEA) and squamous cell carcinoma antigen (SCC) as a supplementary diagnostic test for ASC. We retrospectively analyzed the preoperative serum CEA and SCC levels in 34 patients with lung ASC, 35 cases of lung adenocarcinoma patients, 35 cases of lung squamous cell carcinoma patients. 36 cases of lung benign disease patients and 35 cases of healthy people as a control group were also retrospectively collected and analyzed from January 2012 to December 2014 at the Zhejiang Cancer Hospital, China. The differences of CEA and SCC among the groups were evaluated, and the area under the curve (AUC), sensitivity, and specificity were calculated. The levels of SCC and CEA in the lung ASC group were significantly higher than those in the healthy control group and benign disease group (p < 0.05). The SCC level in lung ASC group was significantly higher than that in lung adenocarcinoma group (p < 0.05). CEA and SCC had good diagnostic sensitivity and specificity compared with the healthy control group, and the difference was statistically significant (p < 0.05). Our retrospective study suggested a role for serum CEA and SCC levels as reference markers in the diagnosis of lung ASC. Patients with elevated CEA and SCC levels and diagnosed as lung adenocarcinoma by limited biopsy materials should be offered further work-up to reach an accurate diagnosis and treatment.

    Ten squamous cell carcinomas (in situ or invasive) of the fingernail region were analyzed for the presence of DNA sequences homologous to human papilloma-virus (HPV) by dot blot hybridization. In most patients, the lesions were verrucae of long-term duration that were refractory to conventional treatment methods. Eight of the lesions contained HPV DNA sequences, and in six of these the sequences were related to HPV 16 as deduced from low-stringency nucleic acid hybridization followed by low- and high-stringency washes. Furthermore, the restriction endonuclease digestion pattern of DNA isolated from four of these lesions was diagnostic of episomal HPV 16. The high-frequency association of HPV 16 with periungual squamous cell carcinoma is similar to that reported for HPV 16 with squamous cell carcinomas on mucous membranes at other sites, notably the genital tract. The findings suggest that HPV 16 may play an important role in the development of squamous cell carcinomas of the finger, most notably those lesions that are chronic and located in the periungual area.

    Full Text Available Abstract Nevoid basal cell carcinoma syndrome (NBCCS, also known as Gorlin syndrome, is a hereditary condition characterized by a wide range of developmental abnormalities and a predisposition to neoplasms. The estimated prevalence varies from 1/57,000 to 1/256,000, with a male-to-female ratio of 1:1. Main clinical manifestations include multiple basal cell carcinomas (BCCs, odontogenic keratocysts of the jaws, hyperkeratosis of palms and soles, skeletal abnormalities, intracranial ectopic calcifications, and facial dysmorphism (macrocephaly, cleft lip/palate and severe eye anomalies. Intellectual deficit is present in up to 5% of cases. BCCs (varying clinically from flesh-colored papules to ulcerating plaques and in diameter from 1 to 10 mm are most commonly located on the face, back and chest. The number of BBCs varies from a few to several thousand. Recurrent jaw cysts occur in 90% of patients. Skeletal abnormalities (affecting the shape of the ribs, vertebral column bones, and the skull are frequent. Ocular, genitourinary and cardiovascular disorders may occur. About 5–10% of NBCCS patients develop the brain malignancy medulloblastoma, which may be a potential cause of early death. NBCCS is caused by mutations in the PTCH1 gene and is transmitted as an autosomal dominant trait with complete penetrance and variable expressivity. Clinical diagnosis relies on specific criteria. Gene mutation analysis confirms the diagnosis. Genetic counseling is mandatory. Antenatal diagnosis is feasible by means of ultrasound scans and analysis of DNA extracted from fetal cells (obtained by amniocentesis or chorionic villus sampling. Main differential diagnoses include Bazex syndrome, trichoepithelioma papulosum multiplex and Torre's syndrome (Muir-Torre's syndrome. Management requires a multidisciplinary approach. Keratocysts are treated by surgical removal. Surgery for BBCs is indicated when the number of lesions is limited; other treatments include laser

    Maspin expression is often deregulated in human cancer cells compared to their normal cells due to loss of epigenetic control. In contrast to normal human ovarian surface epithelial (HOSE) cells, ovarian carcinoma cells display a gain of maspin mRNA expression. The objective of this study was to determine whether gain of maspin expression in ovarian cancer is governed by epigenetic mechanisms. We examined the cytosine methylation and chromatin accessibility status of the maspin promoter in normal HOSE cells and ovarian carcinoma cells with real-time RT-PCR, sodium bisulfite genomic sequencing, and chromatin accessibility assays. 5-Aza-2'-deoxycytidine (5-aza-dC) was used to induce demethylation of the maspin promoter. Ad p53 was used to induce transient overexpression of wild-type p53. Normal HOSE cells were maspin-negative in association with methylation of the maspin promoter. In the maspin-positive ovarian cancer cell lines, the maspin promoter was unmethylated. Increased maspin expression in ovarian carcinoma cells was accompanied by a more accessible chromatin structure in the maspin promoter. In the maspin-negative ovarian cancer cell line A222, maspin could be induced following 5-aza-dC treatment or by forced overexpression of p53. These results suggest that changes in cytosine methylation and chromatin accessibility play an important role in maspin expression in human ovarian carcinoma. Deregulation of maspin expression in ovarian cancer is due to loss of epigenetic control as has been shown in other cancers. This observation provides further evidence of the strict epigenetic control of the maspin gene.

    CONCLUSION: These results support the aggressive surgical removal of RCC with IVC thrombus as the initial treatment. Most of the thrombi can be approached and safely controlled by a transabdominal approach without any form of bypass. Tumour thrombus removal provides a high survival chance and offers improvement in quality of life.

    1996-01-01

    Purpose: Because agents that interfere with thiol metabolism and glutathione S-transferase (GST) functions have been shown to enhance antitumor effects of alkylating agents in vitro and in vivo, the present study was conceived on the basis that an inhibitor of GST would enhance the radiation response of some selected human carcinoma cells. Ethacrynic acid (EA) was chosen for the study because it is an effective inhibitor of GST and is a well known diuretic in humans. Methods and Materials: Experiments were carried out with well-established human tumor cells in culture growing in Eagle's minimum essential medium (MEM) supplemented with 10% fetal calf serum (FCS). Cell lines used were MCF-7, MCF-7 adriamycin resistant (AR) cells (breast carcinoma), HT-29 cells (colon carcinoma), DU-145 cells (prostate carcinoma), and U-373 cells (malignant glioma). Cell survival following the exposure of cells to drug alone, radiation alone, and a combined treatment was assayed by determining the colony-forming ability of single plated cells in culture to obtain dose-survival curves. The drug enhancement ratio was correlated with levels of GST. Results: The cytotoxicity of EA was most pronounced in MCF-7, U-373, and DU-145 cells compared to MCF-7 AR and HT-29 cells. The levels of GST activity were found to be lower in those EA-sensitive cells. A significant radiation enhancement was obtained with EA-sensitive cells exposed to nontoxic concentrations of the drug immediately before or after irradiation. The sensitizer enhancement ratio (SER) of MCF-7 cells was 1.55 with EA (20 μg/ml), while the SER of MCF-7 AR was less than 1.1. Based on five different human tumor cells, a clear inverse relationship was demonstrated between the magnitude of SER and GST levels of tumor cells prior to the combined treatment. Conclusion: The present results suggest that EA, which acts as both a reversible and irreversible inhibitor of GST activity, could significantly enhance the radiation response of

    Full Text Available Meningeal metastasis is rare in the clinical course of ovarian carcinoma and its prognosis is extremely poor. We experienced a case of carcinomatous meningitis from metastatic ovarian small cell carcinoma. A 33-year-old woman with atypical genital bleeding, was diagnosed with a right ovarian tumor and referred to our department. She underwent a total abdominal hysterectomy, bilateral salpingo-oophorectomy, omentectomy, and lymphadenectomy. It was an optimal debulking surgery. She was diagnosed with ovarian carcinoma classified as Stage IIIc according to the Féderation Internationale de Gynécologie et d’Obstétrique classification system. Histological findings showed small cell carcinoma of the pulmonary type. The tumor was bilateral with paraaortic lymph node involvement. The patient was treated with irinotecan and cisplatin (CPT-P therapy. After 4 courses of CPTP therapy, multiple liver metastases and Virchow’s lymph node metastases were found. She was treated with amrubicin as a secondline chemotherapy, but the treatment was ineffective. Five months after surgery, the patient complained of severe headache and nausea. Lumbar puncture was performed and cytology was positive. Magnetic resonance brain imaging indicated meningeal thickening. The patient was diagnosed with meningeal metastasis and received 19-Gy whole cranial irradiation. In spite of these treatments, her disease progressed rapidly and she was often drowsy. She died of aspiration pneumonia 6 months after surgery.

    The diagnosis value of a new tumor marker, CYFRA 21-1, was studied in the blood samples collected from 22 controls, and 87 pre-treatment patients with squamous cell carcinoma of the cervix. Sensitivity and specificity of CYFRA 21-1 was was compared with those of squamous cell carcinoma antigen (SCC) measured in the sera of the same patients. Serum CYFRA 21-1 levels were higher in patients with squamous cell carcinoma than in controls (p < 0.05), and correlated with FIGO stage (Stage IIb-IV vs. Stage Ib-IIa, p = 0.0477). Using 2.5 ng/ml as cut-off value, elevated CYFRA 21-1 levels were found in 13.6% of controls, 34.8% of patients with Stage Ib-IIa squamous cell carcinoma of the cervix, and 63.5% of patients with Stage IIb-IV squamous cell carcinoma of the cervix. However, there was less sensitivity and specificity of CYFRA 21-1 than those of SCC in detecting squamous cell carcinoma of the cervix. CYFRA 21-1 may not be a better tumor marker than SCC for squamous cell carcinoma of the cervix. (author)

    Full Text Available Patients with brain metastasis from renal cell carcinoma (RCC or melanoma have historically had very poor prognoses of less than one year. Stereotactic radiosurgery (SRS can be an effective treatment for patients with these tumors. This study analyzes the effect of pretreatment prognostic factors on overall survival (OS for RCC and melanoma patients with metastasis to the brain treated with SRS. A total of 122 patients with brain metastases from either RCC or melanoma were grouped by age at brain metastasis diagnosis, whether they received whole brain radiation therapy (WBRT in addition to SRS, or they underwent surgical resection, Karnofsky Performance Score (KPS, number of brain metastases, and primary tumor. Median survival times for melanoma patients and RCC patients were 8.20 ± 3.06 and 12.70 ± 2.63 months, respectively. Patients with >5 metastases had a significantly shorter median survival time (6.60 ± 2.45 months than the reference group (1 metastasis, 10.70 ± 13.40 months, p = 0.024. Patients with KPS ≤ 60 experienced significantly shorter survival than the reference group (KPS = 90–100, with median survival times of 5.80 ± 2.46 months (p < 0.001 and 45.20 ± 43.52 months, respectively. We found a median overall survival time of 12.7 and 8.2 months for RCC and melanoma, respectively. Our study determined that a higher number of brain metastases (>5 and lower KPS were statistically significant predictors of a lower OS prognosis.

    To evaluate the prognostic impact of retroperitoneal lymph node dissection (RPLD) performed during nephroureterectomy on time to recurrence and survival in patients with infiltrative transitional cell carcinoma (TCC) of the upper urinary tract. The charts of 82 patients with T2-T4 TCC of the upper tract were retrospectively reviewed. The median patient age was 67.7 yr. Seventy-nine patients underwent nephroureterectomy and three had partial nephrectomy. Forty patients (48.8%) had RPLD with removal of more than five nodes after nephroureterectomy (group 1), whereas 42 (51.2%) had nephroureterectomy only (group 2). Median follow-up was 64.7 mo. The prognostic role of RPLD, T (2 vs. 3-4), G (2 vs. 3), N (0 vs. 1-2 vs. x), age (65 yr) and sex on time to recurrence and survival were evaluated. Median time to recurrence and overall survival were 51.2 and 52.5 mo, respectively, in group 1 and 18.5 and 21.2 mo in group 2. Univariate analysis demonstrated that RPLD and T and N status were significantly related both to time to recurrence (p=0.009, 0.008, and 0.009, respectively) and survival (p=0.000006, 0.003, and 0.003). When analyzed using the Cox proportional hazard model, RPLD and T category were the only two factors demonstrating independent significance on overall survival (p=0.004 and 0.008). The results indicate a possible curative role of RPLD in the treatment of patients with infiltrative TCC of the upper urinary tract. Further randomized trials are needed to confirm these results.

    Merkel cell carcinoma (MCC) is a rare, agressive, neurocutaneous malignancy with a high potential to metastasize. We present a 59 year-old woman referred to general surgery department with a complaint of epigastric pain. The abdominal computed tomography (CT) performed and revealed amass of 3 cm in the head of the pancreas. The significant debate in the patient's medical history was that she had a MCC in size of 5 cm removed from the left gluteal region 7 months ago. Following preoperative preparation a pancreatic oduodenectomy with Whipple procedure was performed fort hepancreatic head mass. As the tumor showed morphologically similar properties with the patient's primary neoplasm, it was accepted as a metastatic MCC. Following the operation the patient received adjuvant chemotherapy and at a 30 months follow-up it was observed that the patient is disease free and has no complications related to the disease progression or recurrence. Although MCC is an aggresive and poor prognostic tumor, good results can be obtained with correct diagnosis and proper surgical treatment. Celsius.

    Basal cell carcinoma (BCC) is the most common skin cancer in fair-skinned individuals. Although lymph node or visceral metastases are observed in less than 0.5 % of all cases, BCC can have a fatal course due to its highly invasive growth pattern. To provide a comprehensive update on diagnosis, treatment, and prevention of BCC. We review the current literature and recommendations of the German guidelines on treatment and prevention of skin cancer. The most pertinent developments are summarized in this review article. The use of optical coherence tomography and reflectance confocal microscopy can significantly improve the diagnosis of BCC compared with clinical assessment and dermoscopy alone. Mohs micrographic surgery remains the therapeutic gold standard for tumors in the head and facial area and tumors with high-risk features. The application of imiquimod, 5‑fluorouracil, or photodynamic therapy should be restricted to low-risk superficial tumors. Topical inhibitors of the sonic hedgehog (SHH) pathway are currently being evaluated in early clinical trials. In contrast, vismodegib and sonidegib have been approved for the systemic treatment of locally advanced and metastatic BCC with good response rates. The most common adverse events of both agents are muscle cramps, dysgeusia, diffuse alopecia, weight loss, and fatigue. In an Australian phase III trial, oral nicotinamide (vitamin B3) reduced the occurrence of new BCC by 20 % in skin cancer patients. Targeted therapy with SHH inhibitors has improved the prognosis of locally advanced and metastatic BCC, albeit at the cost of a significant number of adverse events.

    Full Text Available An 85-year-old male presented with painless bulging lesion over the cornea. Clinical history, diagnostic imaging studies, and histopathologic sections were evaluated. The patient clinically displayed an vascularized conjunctival lesion located at the superior bulbar conjunctiva with extension onto cornea covering 2/3 of his pupillary aperture superiorly. His visual acuity was counting fingers at 4 m. The patient underwent a total excision of the lesion including conjunctival and corneal parts. Histopathologic evaluation revealed spindle cell carcinoma which involves the whole conjunctival squamous epithelium with significant polarity loss, nuclear enlargement with hyperchromasia and pleomorphism, and mitotic activity. Diagnosis of spindle cell carcinoma is challenging because of overlapping histopathological features with other spindle cell tumors. The detailed pathologic examination is very important for the decision of proper treatment.

    Small cell carcinoma is a rare malignant tumor of the larynx. Since this lesion was first described, only 58 cases have been reported in the literature. Between December 1985 and March 1992, five patients with small cell carcinoma of the larynx were treated at the Hospital de la Santa Creu i Sant Pau in Barcelona, Spain. One patient was treated with radiation therapy alone, three patients with chemotherapy and radiation therapy, and one patient with surgery, chemotherapy and radiation therapy. Local and distant control was achieved in only one patient who was observed for 12 months after radiation therapy. Four patients died, one of local disease without distant metastasis at 6 months following treatment, one of local and distant disease at 53 months after radiation therapy, and two of distant metastasis without local disease at 22 and 36 months following treatment. In spite of the fact that only one of the five patients presented in this series is alive and free of disease 12 months following treatment, recent published information suggests that chemotherapy and radiotherapy are currently the most effective form of therapy for small cell carcinoma of the larynx. 16 Refs

The need for development of better therapeutics along with a greater understanding of the relationship between the immune system and malignancies has led to a new therapeutic modality, immune modulators, particularly checkpoint inhibitors in HNSCC. It is now well recognized that HNSCC circumvents crucial pathways utilized by the immune system to escape surveillance. These hijacked pathways include impairing tumor antigen presentation machinery and co-opting checkpoint receptors. This understanding has led to the development of monoclonal antibodies targeting checkpoint receptors and has resulted in promising outcomes in HNSCC. This article describes the mechanisms that HNSCC utilizes to escape immune surveillance, clinical impact of checkpoint inhibitors (with a focus on pembrolizumab, ongoing studies, and future directions.

    A bibliographic review was conduced on the use of 5-methyl aminolevulinate in dermatology, specifically in the treatment of actinic keratosis, epidermoid carcinoma and basal cell carcinoma. The basic fundamentals of photodynamic therapy are described. The preparation and method of use of photodynamic therapy with 5-methyl aminolevulinate (MAL-PDT) are detailed. The clinical studies that were realized with photodynamic therapy for the treatment of actinic keratosis, epidermoid carcinoma and basal cell carcinoma are mentioned. Different photo-inducible agents and other current therapeutic options of first-line are compared. The MAL-PDT has have the advantage of to present less side effects and the same have been more tolerable than liquid nitrogen and 5 fluorouracil. The MAL-PDT has been considered as an effective option for the treatment of Bowen's disease. Invasive epidermoid carcinoma has existed without evidence to support the routine use of this therapeutic. For superficial basal cell carcinoma, the MAL-PDT has presented a high cure rate and transient and manageable side effects in extensive and multiple lesions. The MAL-PDT has been an effective and safe treatment in patients with basal cell carcinoma, for those with less depth of 2mm. The MAL-PDT could play an important role in the field of prevention with immunosuppressed patients, particularly, those that have required transplant and its immunosuppression has been pharmacological. The use or not of the MAL-PDT, should be evaluated individually for each patient and to have suitable characteristics for each disease that was cited in this review. The photodynamic therapy with 5-methyl aminolevulinate has been a therapeutic modality of considerable economy, however, it should be evaluated in the context of number of inquiries and side effects that have offered other therapeutic modalities [es

    We performed a retrospective analysis to compare short term results of induction chemotherapy-radiotherapy versus concurrent chemo-radiotherapy in patients with locally advanced nasopharyngeal carcinoma. From Oct. 1989 to May 1998, 62 patients with locally advanced nasopharyngeal carcinoma were treated with induction chemotherapy followed by radiotherapy (induction group) or concurrent chemo-radiotherapy (concurrent group). Induction chemotherapy was done for 50 patients, and concurrent chemotherapy for 12 patients. Age, sex, performance status, and pathologic types were evenly distributed between two groups. Stage distribution showed 32% with llB, 30% with III, and 38% with IV in induction group, and 50%, 33.3%, and 16.7% in concurrent group, respectively. Chemotherapy regimen was CF (cisplatin and 5-FU) in both groups, and drug delivery method also same. Cisplatin 100 mg/m{sup 2} was intravenously infused on day 1, and 5-FU 1,000 mg/m{sup 2} on day 2-6. This was repeated at 3 weeks interval. At the end of radiotherapy, total cycles of chemotherapy were 1-3 (median 2) in both groups. Conventionally fractionated radiotherapy with daily fraction size 1.8-2.0 Gy and 5 fractions/week was done. Total dose was 69.4-86 Gy(median 73.4 Gy) for induction group, and 69.4-75.4 Gy (median 70.8 Gy) for concurrent group. Follow-up time was 9 -116 months (median 40.5 months) for induction group, 14-29 months (median 21 months) for concurrent group, respectively. Overall 2 year survival rate (2YSRj for all patients was 78.7%. According to treatment modality, 2YSR were 77% for induction group, 87% for concurrent group (p>0.05). 2 year disease-free survival rate were 56% and 81% (p>0.05), respectively. Complete response to treatment were 75.5% for induction group and 91.7% for concurrent group, but there was no statistical difference. The incidence of grade 3- 4 hematologic toxicity during radiotherapy was not differ between two groups, but grade 2 leukopenia was more frequent in

    Papillary renal cell carcinoma is a subgroup of malignant renal epithelial neoplasms. Its occurrence in allograft transplanted kidney has not been debated in the literature. We report two pathologically proven cases and discuss the clinical hypothesis for such neoplasms and the aspect on MR images. The paramagnetic effect of the iron associated with an absence of signal coming from calcifications is a plausible explanation for this unusual hypointense appearance on T2-weighted sequence.

    Full Text Available Extrapulmonary small cell carcinomas (EPSCC are extremely rare. Most reports indicate success with therapy directed at the tumor as if it was pulmonary small cell carcinoma Primary small cell carcinoma of the breast is an uncommon form of EPSCC. Differentiating between a primary small cell carcinoma of the breast from metastatic disease to the breast is very important. According to the literature, there have been approximately 70 cases reported worldwide. Of these cases, only two cases are documented in men. Prognosis is varied and depends on stage of disease at presentation. A combination of surgery, chemotherapy and/or radiation is required to adequately treat patients with small cell carcinoma of the breast. We present a case of a male patient diagnosed with stage IV non-small cell lung carcinoma first and then subsequently diagnosed with a concurrent small cell carcinoma of the breast responding to treatment with concurrent chemotherapy and radiation.

    2015-11-01

    Full Text Available Background: Cytologic diagnosis of pulmonary adenoid cystic carcinoma (AdCC is frequently challenging and differential diagnosis with small cell carcinoma is often difficult. Methods: Eleven cytologically diagnosed cases of pulmonary AdCC were collected and reviewed according to fifteen cytomorphologic characteristics: small cell size, cellular uniformity, coarse chromatin, hyperchromasia, distinct nucleolus, frequent nuclear molding, granular cytoplasm, organoid cluster, sheet formation, irregular border of cluster, hyaline globule, hyaline basement membrane material, individual cell necrosis or apoptotic body, and necrotic background. Twenty cases of small cell carcinoma and fifteen cases of non-pulmonary AdCC were also reviewed for the comparison. Results: Statistically significant differences were identified between pulmonary AdCC and small cell carcinoma in fourteen of the fifteen cytomorphologic criteria (differences in sheet formation were not statistically significant. Cellular uniformity, distinct nucleolus, granular cytoplasm, distinct cell border, organoid cluster, hyaline globule, and hyaline basement membrane material were characteristic features of AdCC. Frequent nuclear molding, individual cell necrosis, and necrotic background were almost exclusively identified in small cell carcinoma. Although coarse chromatin and irregular cluster border were observed in both, they favored the diagnosis of small cell carcinoma. Hyaline globules were more frequently seen in non-pulmonary AdCC cases. Conclusions: Using the fifteen cytomorphologic criteria described by this study, pulmonary AdCC could be successfully distinguished from small cell carcinoma. Such a comprehensive approach to an individual case is recommended for the cytologic diagnosis of pulmonary AdCC.

    To determine the computed tomographic (CT) characteristics of nonfunctioning islet cell carcinoma of the pancreas, the CT scans of 27 patients with that disease were reviewed. The pancreatic tumor was identified as a mass in 26 patients (96%) Of the 25 tumors evaluated with contrast enhancement, 20 became partially diffusely hyperdense relative to nearby normal pancreatic tissue. Hepatic metastases were identified in 15 patients (56%), regional lymphadenopathy in 10 (37%), atrophy of the gland proximal to the tumor in six (22%), dilatation of the biliary ducts in five (19%), and dilatation of the pancreatic duct in four (15%). The CT appearances of the nonfunctioning islet cell tumors were compared with those of 100 ordinary (ductal) pancreatic adenocarcinomas. Although the two types of tumors were sometimes indistinguishable, features found to be more characteristic of islet cell carcinoma included a pancreatic mass of unusually large size, calcification within the tumor, and contrast enhancement of either the primary tumor or hepatic metastases. Involvement of the celiac axis or proximal superior mesenteric artery was limited to ductal carcinoma.

    Full Text Available Abstract Background Leptomeningeal carcinomatosis occurs in patients with cancer at the rate of approximately 5%; it develops particularly in patients with breast cancer, lung cancer, melanoma, leukemia, or malignant lymphoma. We describe a rare case of leptomeningeal carcinomatosis in which spinal intradural squamous cell carcinoma with no lesions in the cerebral meninges and leptomeninx, was the primary lesion. Methods A 64-year-old man complained of sacral pain. Although the patient was treated with analgesics, epidural block and nerve root block, sacral pain persisted. Since acute urinary retention occurred, he was operated on. The patient was diagnosed as having an intradural squamous cell carcinoma of unknown origin. Results Since the patient presented with a slightly decreased level of consciousness 2 months after surgery, he was subjected to MRI scanning of the brain and spinal cord, which revealed disseminated lesions in the medulla oblongata. The patient died of pneumonia and sepsis caused by methicillin-resistant Staphylococcus aureus 5 months after surgery. Conclusion We report the first case of a patient with intradural squamous cell carcinoma with unknown origin that developed independently in the sacrum.

    Full Text Available Transarterial radioembolization (TARE with yttrium 90 (90Y, an intra-arterial procedure performed by interventional radiologists, has begun being utilized in managing hepatocellular carcinoma (HCC in Korea. There are two available TARE products: glass and resin microspheres with different physical characteristics. All patients undergoing TARE must be assessed with clinical examination and laboratory tests as well as a thorough angiographic evaluation. TARE is safe and effective in the treatment of unresectable HCC, as it has longer time-to-progression, greater ability to downsize tumors for liver transplantation, less post-embolization syndrome, and shorter hospitalization compared with chemoembolization. TARE can also serve as an alternative to ablation, surgical resection, portal vein embolization, and sorafenib. The utility of TARE continues to expand with new insights in interventional oncology.

  5. Oral leukoplakia and oral cavity squamous cell carcinoma.

    Science.gov (United States)

    Bewley, Arnaud F; Farwell, D Gregory

    Oral leukoplakia is defined as a white oral lesion not related to another disease process. These lesions are largely asymptomatic, and the clinical relevance of oral leukoplakia is primarily tied to its association with oral cavity squamous cell carcinoma. Timely workup and effective management of these lesions can reduce the risk of malignant transformation and promote early diagnosis of invasive tumors. A biopsy should be performed promptly of any persistent or suspicious leukoplakia with subsequent management dictated by histologic findings. Benign lesions can be observed or treated with topical therapy, and dysplastic lesions should be excised. Some risk of malignant transformation remains even after treatment, and close follow-up is required. Oral cavity squamous cell carcinoma is an aggressive malignancy that can result from malignant conversion of oral leukoplakia or occur de novo. These tumors are primarily treated with surgical resection and adjuvant radiation or chemoradiation as dictated by histopathologic findings. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available The squamous cell carcinoma is a malignant tumor that originates in the epidermal layer skin from the differentiation of keratinocytes. It has high incidence in dogs, cats, horses and cattle. Horses often occur in mucocutaneous junctions, areas like penis and foreskin are the most affected. The incidence is higher in castrated equines with more than 16 years old. This case describes a castrated crossbred horse, actually with 7 years old. The animal presented a mass in foreskin region with evolution of three months. Diagnosed as squamous cell carcinoma by aspirative cytology and biopsy. Surgical tumor mass excision was chosen as treatment. Two months after surgery there was local recurrence of tumor. Euthanasia was performed and a necropsy later in which was found the tumor invaded the adjacent musculature extending from the spine in sacral region between vertebres S1 and S2.

    Sixty patients with squamous cell carcinoma of the oropharynx treated at our hospital from 1991 through 1999 were analyzed. In terms of curative treatments, definitive radiotherapy or curative surgery after neoajuvant chemotherapy had been mainly applied for advanced cases until 1997. Since 1998, advanced cases have been treated with concomitant chemoradiotherapy. The cause-specific survival rate at 5 years for the 60 patients was 50% (stage I, II, 100%; III, 45%; IV A, 36%; IV B, 0%). In the 35 patients with operable advanced-stage disease, the 5-year cause-specific survival rate was 35% in cases treated with definitive radiotherapy, and 66% in those treated with curative surgery, respectively. All 12 operable patients treated with concomitant chemoradiotherapy showed complete response, and 10 patients in this group are disease-free now. However, many problems in definitive treatment modalities, including concomitant chemoradiotherapy for advanced cases with oropharyngeal carcinoma, have not been clarified yet. (author)

    Full Text Available Efficacy of new molecularly targeted drugs in the treatment of renal cell carcinoma (RCC, confirmed in clinical studies in relation to survival and prolongation of time to progression, has became a big chance for patients with metastatic renal cell cancer. Axitinib is a potent and selective receptor tyrosine kinase for vascular endothelial growth factor (VEGFR-1, -2, -3, platelet-derived growth factor  (PDGRF- and c-KIT. This is a case report of a 57-year old female patient with a history of left nephrectomy due to clear cell renal cell carcinoma. The patient had received three prior systemic treatments (interferon – sorafenib – everolimus. After consecutive progression the patient was qualified to 4th line therapy – axitinib at a dose of 5 mg twice daily. Partial response to treatment was achieved. After 6 months therapy was stopped due to the disease progression. The total time to progression was 37.5 months. The total survival time from the disease diagnosis was 45 months. Based on literature date and own experience we showed that sequential treatment RCC is associated with improved survival. In summary, axitinib may be an effective drug after failure of tyrosine-kinase inhibitor (TKI therapy in previous lines of therapy.

    This retrospective study was undertaken to analyze data from patients receiving iodine-125 ([{sup 125}I]) seed brachytherapy postoperatively for the treatment of acinic cell carcinoma (ACC) of the parotid gland along with the following risk factors: residual tumor, recurrent tumor, facial nerve invasion, positive resection margins, advanced tumor stage, or tumor spillage. Twenty-nine patients with ACC (17 females, 12 males; age range, 13-73 years; median age, 37.3 years) were included. Median follow-up was 58.2 months (range, 14-122 months). Patients received [{sup 125}I] seed brachytherapy (median actuarial D90, 177 Gy) 3-41 days (median, 14 days) following surgery. Radioactivity was 18.5-33.3 MBq per seed, and the prescription dose was 80-120 Gy. The 3-, 5-, and 10-year rates of local control were 93.1, 88.7, and 88.7 %, respectively; overall survival was 96.6, 92, and 92 %; disease-free survival was 93.1, 88.4, and 88.4 %; and freedom from distant metastasis was 96.6, 91.2, and 91.2 %. Lymph node metastases were absent in all patients, although two patients died with distant metastases. Facial nerve recovery was quick, and no severe radiotherapy-related complications were noted. Recurrence history, local recurrence, and distant metastasis significantly affected overall survival. Postoperative [{sup 125}I] seed brachytherapy is effective in treating ACC and has minor complications. Patients with a history of recurrence showed poor prognosis and were more likely to experience disease recurrence and develop metastases. (orig.)

    Metastasis to the thyroid gland from distant cancer is rare, and, in some cases, is a diagnostic challenge. Here, we report a case of metastatic renal cell carcinoma of the thyroid gland. A 77-year-old man presented with a neck mass detected about 1 month previously. He had undergone a right nephrectomy owing to renal cell carcinoma 14 years previously. Fine needle aspiration cytology showed a few atypical follicular cells with nuclear atypia. Under a tentative diagnosis of papillary thyroid carcinoma, a total thyroidectomy was performed. The histologic and immunohistochemical studies of the surgical specimens indicated that the thyroid masses were metastatic renal cell carcinoma to the thyroid.

    Basal cell carcinoma is the most common form of skin cancer, especially in elderly people. Pigmented basal cell carcinoma is a rare subtype and has been described in the literature as a nodular and hyperpigmented lesion; rarely, it can appear as an extensive pigmented plate, which may be clinically indistinguishable from superficial spreading melanoma and Bowen disease. Dermatoscopy has a high sensitivity in the diagnosis of basal cell carcinoma. When Menzies criteria are used; however, the final diagnosis is made by histopathology. The objective of the present report is to analyze the case of a patient with pigmented basal cell carcinoma simulating a superficial spreading melanoma.

    The median survival of patients with small cell neuroendocrine carcinoma is significantly shorter than that of patients with classic acinar-type adenocarcinoma. Small cell neuroendocrine carcinoma is traditionally diagnosed based on histologic features because expression of current immunohistochemical markers is inconsistent. This is a challenging diagnosis even for expert pathologists and particularly so for pathologists who do not specialize in prostate cancer. New biomarkers to aid in the diagnosis of small cell neuroendocrine carcinoma are therefore urgently needed. We discovered that FOXA2, a pioneer transcription factor, is frequently and specifically expressed in small cell neuroendocrine carcinoma compared with prostate adenocarcinoma from published mRNA-sequencing data of a wide range of human prostate cancers. We verified the expression of FOXA2 in human prostate cancer cell lines and xenografts, patient biopsy specimens, tissue microarrays of prostate cancers with lymph node metastasis, primary small cell neuroendocrine carcinoma, and metastatic treatment-related small cell neuroendocrine carcinoma and cases from a rapid autopsy program. FOXA2 expression was present in NCI-H660 and PC3 neuroendocrine cell lines, but not in LNCAP and CWR22 adenocarcinoma cell lines. Of the human prostate cancer specimens, 20 of 235 specimens (8.5%) showed diagnostic histologic features of small cell neuroendocrine carcinoma as judged histologically. Fifteen of 20 small cell neuroendocrine carcinoma tissues (75%) showed strong expression of FOXA2 (staining intensity 2 or 3). FOXA2 expression was also detected in 9 of 215 prostate cancer tissues (4.2%) that were histologically defined as adenocarcinoma. Our findings demonstrate that FOXA2 is a sensitive and specific molecular marker that may be extremely valuable in the pathologic diagnosis of small cell neuroendocrine carcinoma.

  17. α-Mangostin Induces Apoptosis and Cell Cycle Arrest in Oral Squamous Cell Carcinoma Cell

    Full Text Available Mangosteen has long been used as a traditional medicine and is known to have antibacterial, antioxidant, and anticancer effects. Although the effects of α-mangostin, a natural compound extracted from the pericarp of mangosteen, have been investigated in many studies, there is limited data on the effects of the compound in human oral squamous cell carcinoma (OSCC. In this study, α-mangostin was assessed as a potential anticancer agent against human OSCC cells. α-Mangostin inhibited cell proliferation and induced cell death in OSCC cells in a dose- and time-dependent manner with little to no effect on normal human PDLF cells. α-Mangostin treatment clearly showed apoptotic evidences such as nuclear fragmentation and accumulation of annexin V and PI-positive cells on OSCC cells. α-Mangostin treatment also caused the collapse of mitochondrial membrane potential and the translocation of cytochrome c from the mitochondria into the cytosol. The expressions of the mitochondria-related proteins were activated by α-mangostin. Treatment with α-mangostin also induced G1 phase arrest and downregulated cell cycle-related proteins (CDK/cyclin. Hence, α-mangostin specifically induces cell death and inhibits proliferation in OSCC cells via the intrinsic apoptosis pathway and cell cycle arrest at the G1 phase, suggesting that α-mangostin may be an effective agent for the treatment of OSCC.

    The treatment of advanced renal cell carcinoma has evolved dramatically over recent years. In this review, we will summarize current and emerging therapies based on molecular targets and provide insight into treatment strategy for metastatic renal cell carcinoma. We have witnessed a paradigm shift in the therapeutic landscape as treatment was formerly reliant on cytokine-based agents which have now been replaced with therapies targeting angiogenesis, mammalian target of rapamycin pathways, and immune responses. These dramatic changes are primarily due to our improved understanding of the underlying mutations and molecular mechanisms leading to tumorigenesis and progression. We now have targeted agents in the form of small-molecule tyrosine kinase inhibitors, monoclonal antibodies, and mTOR inhibitors. Moreover, immunotherapy-targeting checkpoints of T-lymphocyte activity has provided increased overall survival and a new class of agents with potential to radically change the treatment options. With these agents and their combination, durable responses are increasingly seen even though treatment resistance remains a huge challenge. New treatment strategies are rapidly developing and the therapeutic landscape is expected for further evolution.

    Hacker, S M; Flowers, F P

    1993-06-01

    Although squamous cell carcinoma of the skin is still less common than basal cell carcinoma, its incidence is increasing at an alarming rate. Cumulative sun exposure is a major risk factor, and deterioration of the ozone layer combined with life-style choices that promote time in the sun may account for part of the increased incidence. Other risk factors for squamous cell carcinoma include exposure to ionizing radiation, arsenic, or industrial chemicals; viral infection; preexisting burns and scars; and immunosuppression. Actinic keratosis is considered a precancerous lesion that should be watched closely. Treatment methods for squamous cell carcinoma vary depending on the size and location of the lesion. Knowledge of high-risk locations and appropriate treatment choices ensures proper care and decreases the likelihood of metastasis.

    Background and Purpose: In a retrospective study the role of radiation therapy for the treatment of primary tracheal carcinoma was investigated. Patients and Methods: Between 1984 and 1997, 25 patients with primary tracheal carcinoma were treated with external beam radiotherapy (17 squamous-cell carcinoma [SCC], 8 adenoid cystic carcinoma [ACC], median dose SCC 60 Gy, ACC 55 Gy). An additional brachytherapy boost was carried out in 10/25 patients (median dose SCC 18 Gy, ACC 15 Gy). Ten patients underwent operative treatment. Results: The median survival (Kaplan-Meier) for patients with SCC was 33 months (ACC 94.2). The 1-, 2- and 5-year survival rates (Kaplan-Meier) for patients with SCC were 64.7% (ACC 85.7%), 64.7% (ACC 85.7%), and 26% (ACC 85.7%). Patients with ACC and patients with a complete remission after treatment had a significantly better survival probability (log rank test, p [de

    Squamous cell carcinoma (SCC) of the rectum is an extremely rare malignancy, accounting for 0.1-0.2% of rectal malignancies. It is associated with ulcerative colitis, prior radiation, schistosomiasis, ovarian cancer, endometrial cancer, human papilloma virus, colocutaneous fistulas and colonic duplication. Prior reported cases of SCC of the rectum have involved treatment with brachytherapy and external beam radiation. This case is particularly interesting because of the remote exposure of radiation (21 years previously) and the subsequent development of SCC of the rectum. Although extremely rare, SCC of the rectum can occur decades after radiation exposure. (author)

    We report a case of a 46-year-old female who presented with a persistent lesion on the inferior right breast. The lesion was located within the scar from a breast augmentation procedure 12 years ago. The lesion had been treated as several conditions with no improvement. Biopsy revealed a superficial and nodular basal cell carcinoma, and the lesion was successfully removed with Mohs micrographic surgery. Basal cell carcinoma arising in a surgical scar is exceedingly rare with only 13 reported cases to date. This is the first reported case of basal cell carcinoma arising in a breast augmentation scar. We emphasize the importance of biopsy for suspicious lesions or those refractory to treatment, particularly those lesions that form within a scar.

    To investigate the expression of promyelocytic leukaemia (PML) protein of PML protein in Bowen's disease (BD), skin squamous cell carcinoma (SCC) and basal cell carcinoma (BCC) and explore the role of PML in the pathogenesis of these diseases. PML protein in normal skin tissues and lesions of Bowen's disease, SCC and BCC were detected with immunohistochemistry. Normal skin tissues did not express PML protein. In BCC, PML showed rather low expressions in the skin lesions (8.69% in cell nuclei and 4.35% in cytoplasm). The lesions in BD and SCC (grade I and II) showed obvious overexpression of PML protein in the cell nuclei and cytoplasm, and its expression in the cell nuclei of these lesions was significantly higher than that in grade III-IV SCC. PML protein may play an important role in the early stage of SCC, and its overexpression may contribute to the carcinogenesis and metastasis of SCC.

  4. Advances in the management of basal cell carcinoma

    2015-01-01

    Basal cell carcinoma (BCC), a malignant neoplasm derived from non-keratinizing cells that originate in the basal layer of the epidermis, is the most common cancer in humans. Several factors such as anatomic location, histologic features, primary or recurrent tumors, and patient characteristics influence the choice of treatment modality for BCC. Mohs micrographic surgery (MMS) facilitates optimal margin control and conservation of normal tissue for the management of BCC; however, other treatment modalities may also be implemented in the correct clinical scenario. Other treatment modalities that will be reviewed include simple excision, electrodesiccation and curettage, cryotherapy, topical immunotherapy and chemotherapy, photodynamic therapy, and radiation therapy. In addition, targeted molecular therapeutic options for the treatment of advanced or metastatic BCC will be discussed in this informal review based on recent literature obtained by using PubMed with relevant search terms.

  5. Trimodal therapy in squamous cell carcinoma of the esophagus

    2011-10-01

    Full Text Available Abstract Patients with ESCC (squamous cell carcinoma of the esophagus are most commonly diagnosed with locally advanced tumor stages. Early metastatic disease and late diagnosis are common reasons responsible for this tumor's poor clinical outcome. The prognosis of esophageal cancer is very poor because patients usually do not have symptoms in early disease stages. Squamous cell carcinoma of the esophagus frequently complicates patients with multiple co-morbidities and these patients often require interdisciplinary diagnosis and treatment procedures. At present time, neoadjuvant radiation therapy and chemotherapy followed by surgery are regarded as the international standard of care. Meta-analyses have confirmed that this approach provides the patient with better local tumor control and an increased overall survival rate. It is recommended that patients with positive tumor response to neoadjuvant therapy and who are poor surgical candidates should consider definitive radiochemotherapy without surgery as a treatment option. In future, EGFR antibodies may also be administered to patients during therapy to improve the current treatment effectiveness. Positron-emission tomography proves to be an early response-imaging tool used to evaluate the effect of the neoadjuvant therapy and could be used as a predictive factor for the survival rate in ESCC. The percentage proportions of residual tumor cells in the histopathological analyses represent a gold standard for evaluating the response rate to radiochemotherapy. In the future, early response evaluation and molecular biological tests could be important diagnostic tools in influencing the treatment decisions of ESCC patients.

    To describe a series of cases of basal cell carcinomas of the eyelid. A descriptive and retrospective study was conducted by reviewing the medical outcome, histopathological history, and photographic images of 200 patients with basal cell eyelid carcinomas. All were treated in the Herzog Carl Theodor Eye Hospital in Munich, Germany, between 2000 and 2013. In the present study, it was found that females are more affected than males. The mean age of presentation of the tumor occurred at the age of 70 years. In 50% of the cases the tumor was found on the lower lid, especially medially from the center of the lid. The lid margin was involved in 47% of all tumors. The mean diameter was 9.2mm. The recurrence rate after surgery with histologically clear resection margins was 5%. There was a significant relationship between tumor diameter and age. As tumors where located farther away from medial and closer to the lid margin, they became larger. There is a predominance of women affected by this tumor. This may be related to the fact that the sample was taken from those attending an oculoplastic surgery clinic, where there are generally more women than men attending. The formation of basal cell carcinomas increases with age. The infrequent involvement of the upper lid could be explained by the protection of the the eyebrow. The frequent involvement of the lower lid may be due to the light reflection (total reflection) by the cornea on the lower lid margin. Also chemical and physical effects of the tears may be more harmful on the lower lid. Patients tend to ask for medical help when they are females, younger, when the tumor is closer to the medial canthus or when the tumor is away from the lid margin.

    A 69-year-old man presented with gross hematuria and irritative urinary symptoms. He underwent transurethral resection of his prostate. The prostate chips revealed 70% poorly differentiated carcinoma with neuroendocrine features, initially read as small cell carcinoma, later as basal cell carcinoma. PSA at this time was 0.3. He received 4 cycles of etoposide and cisplatin. After which, rebiopsy of the prostate showed tumor consistent with poorly differentiated basal cell carcinoma. Given progression on chemotherapy, decision was made to proceed with radical prostatectomy. Metastatic workup was negative. Gross extraprostatic invasion was noted but lymph nodes were free of metastatic disease. Copyright © 2012 Elsevier Inc. All rights reserved.

    Merkel cell carcinoma (MCC) was first described in 1972 by Toker, who described five cases of the so-called "trabecular carcinoma of the skin ". MCC is a rare, aggressive skin cancer that affects mainly the elderly. Sun exposed areas are mainly affected, specially the head and neck. Immunohistochemical analysis is essential to reach a correct diagnosis. According to the origin of MCC, the tumor expresses both epithelial and neuroendocrine markers. MCC has a propensity for recurrence, regional and distant metastases. Several treatment options are available, such as surgical excision or Moh's surgery, accompanied by neck dissection or radio and chemotherapy in advanced cases. The present study aims to evaluate the clinical behaviour and the evolution of five cases of this disease that were treated at our institution (reference to 1100000 inhabitants) in the last five years. It is stressed on the bad prognosis of this pathology, which presents high rates of locoregional recurrence, even though the recent advances in radio and chemotherapy.

HCC generally has a more aggressive clinical behavior compared with the other differentiated thyroid cancers, and it is associated with a higher rate of distant metastases. Minimally invasive HCC demonstrates much less aggressive behavior; lesions <4 cm can be treated with thyroid lobectomy alone, and without radioactive iodine (RAI. HCC has been observed to be less iodine-avid compared with other differentiated thyroid cancers; however, recent data have demonstrated improved survival with RAI use in patients with HCC >2 cm and those with nodal and distant metastases. Patients with localized iodine-resistant disease who are not candidates for a wait-and-watch approach can be treated with localized therapies. Systemic therapy is reserved for patients with progressive, widely metastatic HCC. Keywords: thyroid cancer, thyroid nodule, follicular cell carcinoma, Hurthle cell lesion, minimally invasive HCC

    In human papillomavirus (HPV) infections, Langerhans cells (LC) are essential in the control of viral infection. The evolution of HPV-derived lesions in the normal population and in graft patients is drastically different, since a high proportion of papillomas progress towards malignancy in transplant recipients. We analyzed the distribution of markers of LC and T lymphocytes, the level of keratinocyte activation and the prevalence of HPV in a series of epithelial lesions obtained from the normal population and from graft patients. The local immune response of warts, condyloma acuminata, Bowen, basal and squamous cell carcinomas (SCC) showed a moderate to intense inflammatory reaction of HLA-DR positive cells, the intensity of the immune reaction being correlated with the degree of malignancy. In the normal population, CD4-positive cells were mainly overexpressed in the dermal infiltrate of condyloma and malignant lesions, whereas in grafted patients such infiltrates were CD4- and CD8-positive without significant predominance of a single T cell subset. The epidermis of most lesions was characterized by a reduced number of CD1a-positive LC with an altered morphology. This was concomitant with the decrease or loss of beta 2-microglobulin by epithelial cells. HLA-DR antigen was sometimes expressed by keratinocytes in genital lesions and SCC from the normal population but has not been detected in immunosuppressed patients. Whereas in the normal population HPV infection was only detected in benign papillomas, both benign and oncogenic HPV DNA may be present in carcinomas from graft patients.(ABSTRACT TRUNCATED AT 250 WORDS)

    Peritoneum is a site for both primary and secondary tumors. Primary peritoneal tumors are fairly rare. The most common primary tumors of the peritoneum are malignant mesothelioma and serous papillary adenocarcinoma. Clear cell carcinoma of the peritoneum is extremely rare and often misdiagnosed as mesothelioma, serous carcinoma, or metastatic adenocarcinoma, so it represents a diagnostic challenge for both clinicians and pathologists. Up to date, to the best of our knowledge, only 11 cases of primary peritoneal clear cell carcinoma have been reported in the English literature. Distinguishing this tumor of the peritoneum versus ovarian carcinoma can be problematic. Herein, we report a rare case of primary peritoneal clear cell carcinoma occurring in a 49-year-old woman, along with a review of the literature. © The Author(s) 2015.

    Basal cell carcinoma (BCC) typically occurs in sun-exposed sites. Only 16 individuals with umbilical BCC have been described in the literature, and the characteristics of patients with umbilical BCC are summarized. PubMed was used to search the following terms: abdomen, basal cell carcinoma, basal cell nevus syndrome, and umbilicus. Papers with these terms and references cited within these papers were reviewed. BCC of the umbilicus has been reported in five men and 11 women; one man had two tumors. Two patients had basal cell nevus syndrome (BCNS). Other risk factors for BCC were absent. The tumor most commonly demonstrated nodular histology (64%, 9/14); superficial and fibroepithelioma of Pinkus variants were noted in three and two patients, respectively. The tumor was pigmented in eight individuals. Treatment was conventional surgical excision (87%, 13/15) or Mohs micrographic surgery (13%, 2/15); either adjuvant laser ablation or radiotherapy was performed in two patients. The prognosis after treatment was excellent with no recurrence or metastasis (100%, 16/16). In conclusion, BCC of the umbilicus is rare. It usually presents as a tumor with a non-aggressive histologic subtype in an individual with no risk factors for this malignancy. There has been no recurrence or metastasis following excision of the cancer. PMID:27738570
