Abstract
OBJECTIVE Guidelines for treatment of non-small cell lung cancer identify patients with tumors ≤2 cm and pure carcinoma in situ histology as candidates for sublobar resection. Although the merits of lobectomy, sublobar resection, and lymphoid (LN) sampling, have been investigated in early-stage non-small cell lung cancer, evaluation of these modalities in patients with IS disease can provide meaningful clinical information. This study aims to compare these operations and their relationship with regional LN sampling in this population. METHODS The National Cancer Database was used to identify patients diagnosed with non-small cell lung cancer clinical Tis N0 M0 with a tumor size ≤2 cm from 2004 to 2017. The χ2 tests were used to examine subgroup differences by type of surgery. Kaplan-Meier method and Cox proportional hazard model were used to compare overall survival. RESULTS Of 707 patients, 56.7% (401 out of 707) underwent sublobar resection and 43.3% (306 out of 707) underwent lobectomy. There was no difference in 5-year overall survival in the sublobar resection group (85.1%) compared with the lobectomy group (88.9%; P = .341). Multivariable survival analyses showed no difference in overall survival (hazard ratio, 1.044; P = .885) in the treatment groups. LN sampling was performed in 50.9% of patients treated with sublobar resection. In this group, LN sampling was not associated with improved survival (84.9% vs 85.0%; P = .741). CONCLUSIONS We observed no difference in overall survival between sublobar resection and lobectomy in patients with cTis N0 M0 non-small cell lung cancer with tumors ≤2 cm. Sublobar resection may be an appropriate surgical option for this population. LN sampling was not associated with improved survival in patients treated with sublobar resection.

Abstract
the bile duct system and pancreas show many similarities due to their anatomical proximity and common embryological origin. Consequently, preneoplastic and neoplastic lesions of the bile duct and pancreas share analogies in terms of molecular, histological and pathophysiological features. Intraepithelial neoplasms are reported in biliary tract, as biliary intraepithelial neoplasm (BilIN), and in pancreas, as pancreatic intraepithelial neoplasm (PanIN). Both can evolve to invasive carcinomas, respectively cholangiocarcinoma (CCA) and pancreatic ductal adenocarcinoma (PDAC). Intraductal papillary neoplasms arise in biliary tract and pancreas. Intraductal papillary neoplasm of the biliary tract (IPNB) share common histologic and phenotypic features such as pancreatobiliary, gastric, intestinal and oncocytic types, and biological behavior with the pancreatic counterpart, the intraductal papillary mucinous neoplasm of the pancreas (IPMN). All these neoplastic lesions exhibit similar immunohistochemical phenotypes, suggesting a common carcinogenic process. Indeed, CCA and PDAC display similar clinic-pathological features as growth pattern, poor response to conventional chemotherapy and radiotherapy and, as a consequence, an unfavorable prognosis. The objective of this review is to discuss similarities and differences between the neoplastic lesions of the pancreas and biliary tract with potential implications on a common origin from similar stem/progenitor cells.

Abstract
The pathogenesis of vulvar squamous neoplasia has 2 pathways: human papillomavirus (HPV)-dependent and HPV-independent. The HPV-dependent pathway in the vulva follows the same progression as HPV-dependent lesions elsewhere in the gynecologic tract-HPV infection results in high-grade squamous intraepithelial lesion with subsequent progression to basaloid squamous cell carcinoma. The HPV-independent pathway is more complex, with a variety of precursor lesions and molecular alterations. Although the most recognized form of HPV-independent vulvar lesion is differentiated vulvar intraepithelial neoplasia, recent explorations have elucidated new precursors. This review provides an update on HPV-independent risk factors and precursor lesions for squamous cell carcinoma of the vulva.

Abstract
Fourty-one patients underwent breast reconstruction after mastectomy for cancer and reduction plasty of the second breast, over a 36-month period. These plasties were performed only for reasons of asymmetry, in the absence of any positive preoperative finding. Histologic examination using semiserial sectioning of the whole excised sample detected a high frequency of unsuspected cancer 14/41 (34%). There was a strong predominance of in situ carcinomas 11/41 (27%) over invasive carcinomas 3/41 (7%). These results were compared with those of other bilateral cancer series. When such cancers were detected by random biopsies or mastectomies, the rate of in situ carcinomas was much greater than in cancers detected only by physical and mammographic examination.

Abstract
CONTEXT - Invasive pancreatic ductal adenocarcinoma has a greater than 90% mortality rate at 5 years. Understanding noninvasive, curable precursor lesions gives us the best hope for reducing mortality from pancreatic ductal adenocarcinoma. The 3 pancreatic precursor lesions that have been well studied include intraductal papillary mucinous neoplasm, mucinous cystic neoplasm, and pancreatic intraepithelial neoplasia. OBJECTIVE - To give an update on the latest clinical, molecular, and pathologic advances in intraductal papillary mucinous neoplasm, mucinous cystic neoplasm, and pancreatic intraepithelial neoplasia for the general surgical pathologist. DATA SOURCES - The current literature was analyzed and the authors' experiences with institutional and consult material were incorporated. CONCLUSIONS - Our understanding of the molecular alterations that lead from pancreatic precursor lesion to invasive carcinoma continues to evolve. These advances aid clinicians in their treatment decisions and researchers in their search for actionable, druggable targets.

Abstract
Purpose: Response rates to treatment of vulval intraepithelial neoplasia (VIN) with imiquimod and cidofovir are approximately 57% and 61%, respectively. Treatment is associated with significant side effects and, if ineffective, risk of malignant progression. Treatment response is not predicted by clinical factors. Identification of a biomarker that could predict response is an attractive prospect. This work investigated HPV DNA methylation as a potential predictive biomarker in this setting.Experimental Design: DNA from 167 cases of VIN 3 from the RT3 VIN clinical trial was assessed. HPV-positive cases were identified using Greiner PapilloCheck and HPV 16 type-specific PCR. HPV DNA methylation status was assessed in three viral regions: E2, L1/L2, and the promoter, using pyrosequencing.Results: Methylation of the HPV E2 region was associated with response to treatment. For cidofovir (n = 30), median E2 methylation was significantly higher in patients who responded (P ≤ 0.0001); E2 methylation >4% predicted response with 88.2% sensitivity and 84.6% specificity. For imiquimod (n = 33), median E2 methylation was lower in patients who responded to treatment (P = 0.03; not significant after Bonferroni correction); E2 methylation <4% predicted response with 70.6% sensitivity and 62.5% specificity.Conclusions: These data indicate that cidofovir and imiquimod may be effective in two biologically defined groups. HPV E2 DNA methylation demonstrated potential as a predictive biomarker for the treatment of VIN with cidofovir and may warrant investigation in a biomarker-guided clinical trial.

Abstract
CONTEXT - Precursor lesions of urologic malignancies are established histopathologic entities, which are important not only to recognize for clinical purposes, but also to further investigate at the molecular level in order to gain a better understanding of the pathogenesis of these malignancies. OBJECTIVE - To provide a brief overview of precursor lesions to the most common malignancies that develop within the genitourinary tract with a focus on their clinical implications, histologic features, and molecular characteristics. DATA SOURCES - Literature review from PubMed, urologic pathology textbooks, and the 4th edition of the World Health Organization Classification of Tumours of the Urinary System and Male Genital Organs. All photomicrographs were taken from cases seen at Weill Cornell Medicine or from the authors' personal slide collections. CONCLUSIONS - The clinical importance and histologic criteria are well established for the known precursor lesions of the most common malignancies throughout the genitourinary tract, but further investigation is warranted at the molecular level to better understand the pathogenesis of these lesions. Such investigation may lead to better risk stratification of patients and potentially novel treatments.

Abstract
In recentyears, theincidence ofvul- var carcinoma has increased over 400%, specifically in the population of young women. We present a patient with an extensive history of recurrent vulvar carcinoma in situ who underwent multiple surgi- cal procedures and subsequent reconstruction with a skin graft, who then returned with a rare recur- rence in the graft. Multiple hypotheses have been proposedto explain the recurrence ofthis type ofcar- cinoma; however, none provides a solid explanation. It has been noted that the increase in the incidence of vulvar cancer correlates with the increased incidence of HPV infection; the relationship between the two has been well-established. In conclusion, we recommend close and long-term follow-up for high-risk patients with this type of neoplasm.

Abstract
Gastric polyps become a major clinical problem because of high prevalence and tendency to malignant transformation of some of them. The development of gastric hyperplastic polyps results from excessive proliferation of foveolar cells accompanied by their increased exfoliation, and they are macroscopically indistinguishable from other polyps with lower or higher malignant potential. Panendoscopy allows detection and differentiation of gastric polyps, usually after obtaining histopathological biopsy specimens. Unremoved gastric hyperplastic polyps may enlarge and sometimes spontaneously undergo a sequential progression to cancer. For this reason, gastric hyperplastic polyps larger than 5 mm in size should be removed in one piece. After excision of polyps with atypical focal lesion, endoscopic surveillance is suggested depending on histopathological diagnosis and possibility of confirming the completeness of endoscopic resection. Because of the risk of cancer development also in gastric mucosa outside the polyp, neighboring fragments of gastric mucosa should undergo microscopic investigations. This procedure allows for identification of patients who can benefit most from oncological endoscopic surveillance. If Helicobacter pylori (H. pylori) infection of the gastric mucosa is confirmed, treatment strategies should include eradication of bacteria, which may prevent progression of intestinal metaplasia. The efficacy of H. pylori eradication should be checked 3-6 mo later.

Abstract
This article evaluates malignant transformation of lesions presenting in the periocular skin under the eye spectacle nose pad. A non-comparative retrospective chart review of clinical features and pathological findings of patients presenting with periocular malignancies in the exact vicinity where the nose pads of their eye spectacles rested was completed. The study took place in one tertiary oculoplastic referral center between 2007-2013. Ten patients were included, six of whom were male. All subjects wore eye spectacles while awake for at least 15 years, and had an evident suspicious lesion in the exact area that coincided with the resting place of the nose pad. The mean age was 73.5 years (range 65-85 years) and all patients had the lesion present for at least one year. Most cases were squamous skin malignancies (five squamous cell carcinomas [SCC], 2 intra-epidermal carcinomas [IEC], while 3 basal cell carcinomas [BCC]). Treatment involved surgical excision of the lesion with frozen section for margin control and reconstruction with a myocutaneous flap. Periocular malignancies of the inferior medial canthal area, where the nose pad of eye spectacle places pressure, can be easily missed or misdiagnosed. Marjolin ulcers (MU) classically present as an aggressive SCC in area of chronic inflammation, which has been previously correlated to constant pressure, repetitive trauma, or non-healing wounds in other areas of the body. We propose that the traumatic chronic pressure in the infero-medial canthal region from long-term eye spectacle nose pad use, may induce poor lymphatic regeneration leading to an immune system deficiency that predisposes this skin to a malignant transformation. The presence of chronic eye spectacle nose pads also prevents proper and timely detection of such malignancies. Complete excision of these lesions with margin control, adequate follow-up for possible recurrence, and surveillance for new lesions on the patient's contralateral side, is crucial for adequate management.

Abstract
AIM: To investigate the factors influencing the occurrence of gastric varioliform lesions (GVLs) and their possible link with gastric cancer.
METHODS: A 1:1 matched case-control study was performed to retrospectively analyze data from 1638 chronic gastritis patients who had undergone gastroscopy at one of two Chinese hospitals between 2009 and 2014. Patients with GVLs (cases) were compared to those without such lesions (controls). Endoscopic and pathological findings were recorded, along with interview information on Helicobacter pylori (H. pylori) infection, medical, drug and family histories, lifestyle and eating habits. The association between each factor and the occurrence of GVLs was estimated, and then multivariate conditional logistic regression was used to evaluate the independent factors.
RESULTS: The frequency and severity of glandular atrophy, intestinal metaplasia (IM) and low-grade intraepithelial neoplasia were significantly increased in the GVL group (P < 0.01). Overall analysis showed that H. pylori infection [3.051 (2.157, 4.317), P <0.001], allergic respiratory diseases [3.636 (2.183, 6.055), P < 0.001], work-related stress [2.019 (1.568, 2.600), P < 0.001], irregular meals [2.300 (1.462, 3.619), P < 0.001], high intake of spicy food [1.754 (1.227, 2.507), P = 0.002] and high intake of fresh fruit [0.231 (0.101, 0.529), P = 0.001] were significantly correlated with the occurrence of GVLs (positively, except for the latter). Stratified analyses indicated that pickled food consumption in patients over 50 years old [7.224 (2.360, 22.115), P = 0.001] and excessive smoking in men [2.013 (1.282, 3.163), P = 0.002] were also positively correlated, and that, for antral GVLs, vegetable consumption [0.491 (0.311, 0.776), P = 0.002] was negatively correlated.
CONCLUSION: Seven risk factors and two protective factors are determined for GVLs, which were found to be associated with premalignant abnormalities.

Abstract
Serous tubal intraepithelial carcinoma (STIC) is considered the precursor of pelvic serous carcinomas and the earliest malignant alteration in BRCA mutation-positive women. Recently, risk-reducing salpingo-oophorectomy (RRSO) is being performed in BRCA mutation-positive women and STIC is often discovered incidentally in the fallopian tubes. A 62-year-old woman underwent bilateral salpingo-oophorectomy (BSO) for ovarian cysts. Ten months later, cytological screening for the endometrium revealed adenocarcinoma. No atypical tissue was detected by the endometrial curettage. Imaging tests and hysteroscopy found no abnormal findings. She underwent hysterectomy and was diagnosed with STIC originating from the intrauterine portion of the residual fallopian tube. Here, the authors report the first case of STIC being detected during an endometrial cytological examination after BSO. Although STIC associated with the BRCA mutation usually involves the distal fallopian tube, the present case suggests that the intrauterine portion of the fallopian tube should be removed or cauterized during RRSO.

Abstract
We present a 30-year-old woman with atopic dermatitis and ichthyosis vulgaris and a one-year history of an erythematous, scaly plaque on the dorsal surface of her right hand, which developed three years after an accidental exposure to prolonged ultraviolet C (UVC) radiation in a laboratory accident. The plaque, which was initially treated as eczematous dermatitis, was eventually identified histopathologically as squamous-cell carcinoma in situ. Although causation is not definitive, this case is the first to describe development of non-melanoma skin cancer (NMSC) in an area of skin known to be acutely exposed to UVC radiation. As UVC radiation becomes a more frequently used anti-microbial technology, UVC radiation may become a more commonly identified risk factor in the development of NMSC.

Abstract
OBJECTIVE ERRs (estrogen-related receptors) regulate energy metabolism, the cell cycle and inflammatory processes in both normal and cancer cells. Chronic inflammation induced by lichen sclerosus (LS) or human papilloma virus (HPV) precedes vulvar squamous cell carcinoma (vulvar SCC). We investigated the expression of ERRα, ERRβ and ERRγ in normal vulvar skin, LS as well as LS-dependent and LS-independent/HPV-related vulvar SCC. METHODS A total of 203 samples were analyzed for ERRα, ERRβ and ERRγ by using immunohistochemistry. These included 37 normal vulvar skin samples, 110 LS samples, 6 vulvar intraepithelial neoplasia (VIN) samples and 50 vulvar SCC samples. RESULTS A substantial reduction in or disappearance of ERRα was detected in all vulvar SCC samples. A total of 79% of childhood-onset LS and 51% of adulthood-onset LS lesions showed decreases in ERRα staining. A gradual reduction in ERRα cytoplasmic staining was observed from healthy vulvar skin to precursor lesions and further to SCC. Nuclear ERRα staining was observed in 8/33 (24%) LS-dependent and 10/17 (59%) LS-independent SCC samples. CONCLUSIONS ERRα, a key regulator of cell energy metabolism, may play a role in the pathogenesis of both LS and vulvar SCC.

Abstract
Actinic keratoses (AKs) are the most common keratinocytederived precancerous lesion in humans; they can be observed predominantly in fair-skinned individuals on sun-exposed surfaces. The primary risk factor for AKs is cumulative UV exposure from sunlight and/or tanning salons. AKs may present on a patient as a few detectable lesions. In addition to these, there are subclinical (invisible) AKs that are estimated to occur up to 10 times more often than visible AKs, since unprotected skin receives UV radiation from the sun. Clinical and subclinical AK lesions occurring in photo-damaged skin are called field cancerization. A field of change can be up to 7 cm around the primary lesions, resulting in lesions that are genetically similar. AKs are defined at the histologic level by dysplasia and consist of keratinocytes manifesting atypical nuclei that are enlarged, irregular, and hyperchromatic. The histopathologic changes noted in keratinocytic proliferative lesions involve disturbance of normal surface maturation. The degree and extent of keratinocytic atypia vary in these lesions. The atypical keratinocytes show enlarged nuclei with hyperchromasia, dyskeratosis and mitoses in any layer of the epidermis. In lesions of epidermal dysplasias, surface keratinocytic maturation is present, and a granular cell layer is usually noted. In intraepidermal carcinomas, there is full-thickness involvement of the epidermis by the atypical keratinocytes. While molecular techniques have improved our ability to distinguish squamous cell carcinomas (SCCs) from AKs, they have also reinforced the concept that non-melanoma skin cancers arise through a complex series of aberrations at the molecular level. AKs represent a spectrum along the continuum to invasive cancer. They are the most visible manifestation of field cancerization which creates a population of atypical cells with the potential to progress to invasive malignancy capable of metastasis. As the perilesional epithelium also has abnormalities due to photo exposure, understanding the existence of a "cancerization field" should be explained to the patients, reinforcing the importance of preventive clinical follow-up. The aim of the present review was to emphasize the histopathological aspect of the morphological spectrum in AK, and SCCs, also elucidating the clinicopathology of field canceriziation.

Abstract
BACKGROUND There is growing evidence of the protective role of dietary intake of flavonoids and lignans on cancer, but the association with bladder cancer has not been thoroughly investigated in epidemiological studies. We evaluated the association between dietary intakes of total and subclasses of flavonoids and lignans and risk of bladder cancer and its main morphological type, urothelial cell carcinoma (UCC), within the European Prospective Investigation into Cancer and Nutrition (EPIC) study. METHODS A cohort of 477 312 men and women mostly aged 35-70 years, were recruited in 10 European countries. At baseline, dietary flavonoid and lignan intakes were estimated using centre-specific validated questionnaires and a food composition database based on the Phenol-Explorer, the UK Food Standards Agency and the US Department of Agriculture databases. RESULTS During an average of 11 years of follow-up, 1575 new cases of primary bladder cancer were identified, of which 1425 were UCC (classified into aggressive (n=430) and non-aggressive (n=413) UCC). No association was found between total flavonoid intake and bladder cancer risk. Among flavonoid subclasses, significant inverse associations with bladder cancer risk were found for intakes of flavonol (hazard ratio comparing fifth with first quintile (HRQ5-Q1) 0.74, 95% confidence interval (CI): 0.61-0.91; P-trend=0.009) and lignans (HRQ5-Q1 0.78, 95% CI: 0.62-0.96; P-trend=0.046). Similar results were observed for overall UCC and aggressive UCC, but not for non-aggressive UCC. CONCLUSIONS Our study suggests an inverse association between the dietary intakes of flavonols and lignans and risk of bladder cancer, particularly aggressive UCC.

Abstract
AIM We report dermatologists' opinions and clinical practice patterns about clinical factors driving decision making in the management of actinic keratosis (AK) in Italy. METHODS We carried out a cross-sectional survey among 33 Italian dermatologists. Physicians were asked to report their management choices in consecutive patients with AK seen at their practice within 2 weeks since study initiation. We collected patients' clinical and socio-demographic characteristics with a standardized data collection form and assessed physicians' opinions on AK management with a self-reported questionnaire. RESULTS Six hundred fifty-seven patients with new, single AK lesions without evidence of photo-damaged skin in the surrounding areas, were predominantly treated with lesion-directed therapies (primarily cryotherapy). In contrast, physicians preferentially prescribed field-directed therapies to patients with multiple lesions and evidence of photo-damaged skin in AK surrounding areas. However we observed a wide variation in treatment choices and physicians' opinions on AK management. Dermatologists underlined the importance of fostering patients' adherence and minimize therapy side effects. CONCLUSION Overall, our results show that current guidelines regarding management of AK are only partially integrated in dermatology practice. The active dissemination of up-to-date national guidelines might help harmonize clinical decision making in this complex and fast growing therapeutic area.

Abstract
BACKGROUND AND AIMS There are theoretical reasons for suspecting that a high glycemic index (GI) or glycemic load (GL) diet may increase breast cancer risk, perhaps via an effect on the insulin-like growth factor (IGF) axis. However observational studies have produced inconsistent findings and it is controversial whether breast cancer risk is influenced by the carbohydrate characteristics of the diet. We prospectively investigated the association between dietary GI and GL and breast cancer in the Italian section of the European Prospective Investigation into Cancer and Nutrition (EPIC). METHODS AND RESULTS Women were recruited from 1993 to 1998 at five centers: Varese and Turin (north Italy), Florence (central Italy), and Ragusa and Naples (south Italy). Participants completed validated food frequency questionnaires from which GI and GL were estimated. Multivariable Cox proportional hazard regression models quantified the association between breast cancer risk and total carbohydrate intake, GI, and GL. During 11 years of follow-up, 879 breast cancer (797 invasive and 82 in situ) cases were indentified. High dietary GL was associated with increased breast cancer risk (RR 1.45, 95% CI = 1.06-1.99; highest vs. lowest quintile; p-trend 0.029), whereas dietary GI and total carbohydrate had no influence. The association was not modified by menopausal status or body mass index. CONCLUSION Our data indicate that, in a Mediterranean population characterized by traditionally high and varied carbohydrate intake, a diet high in GL plays a role in the development of breast cancer.

Abstract
Mucosal lesions of the upper aerodigestive tract usually concern the squamous epithelium of the surface. Many precancerous alterations now designated as potentially malignant are caused by DNA damage resulting from long term exposure to tobacco and alcohol consumption. The distinction from conditions with a similar phenotype but caused by different reasons such as viral infection may be difficult. Furthermore, a magnitude of similar appearing lesions with different clinical background and different biological behavior are discussed in this paper.

Abstract
OBJECTIVE To assess the incidence, characteristics and outcome of upper urinary tract tumors (UUTTs) that developed in patients who underwent radical cystectomy for urothelial carcinoma. METHODS We performed an analysis of original and review articles that were related to post-cystectomy UUTTs. The articles were published from 1984 through 2011 and were identified by searching the Pub Med database. RESULTS The incidence of post-cystectomy UUTT ranges from 2-6% and is stable over time. The primary risk factors include a tumor in the distal ureter in the cystectomy specimen and signs of multifocal disease (e.g., multiplicity, a history of non-muscle-invasive bladder tumor, diffuse carcinoma in situ and the presence of a tumor in the prostatic urethra). The median time between cystectomy and UUTT exceeded three years in 70% of the reviewed cases. Even with regular radiological follow-up visits, over 50% of cases were diagnosed after clinical onset, and over 70% were in an advanced stage. Currently, a multidetector computed tomography urography is the standard technique for studying the upper urinary tract. In patients with urinary diversion, the maximum yield of cytology can be obtained when this technique is used to confirm a clinical or radiological suspicion of UUTT. Nephroureterectomy is the treatment of choice for these tumors. The high prevalence of high-grade and stage UUTT results in endourological treatment being restricted to only selected cases. Despite surgery, fewer than 30% of post-cystectomy UUTT patients experience prolonged survival. CONCLUSIONS Post-cystectomy UUTT is rare and usually has a late onset. A distal ureteral tumor and the presence of multifocal disease are its primary risk factors. Most cases of post-cystectomy UUTT are diagnosed clinically and in advanced stages.

Abstract
A 36-year-old African man from Guinea with a history of albinism presented with a many-year history of scaling and erythema of the face, neck, and arms. The patient had light eyes, hair, and skin. Physical examination showed extensive photodamage. A skin biopsy specimen from the posterior aspect of the lower leg showed a squamous-cell carcinoma in situ. The most common types of oculocutaneous albinism (OCA), OCA 1 and OCA 2, are autosomal recessive disorders of pigmentation that commonly affect the skin, hair, eyes, and ears. Photodamage and skin cancers plague patients with albinism. In Africa, where albinism is prevalent, albinos face a myriad of social and medical issues. Skin cancer surveillance is an important consideration for albinos, and sun protection is paramount.

Abstract
A flap is described for recreation of the labia majora. The flap was designed for a young woman who developed vulvar squamous cell carcinoma in-situ after immunosuppression for treatment of juvenile rheumatoid arthritis. The patient underwent removal of the labia majora, and was reconstructed with a bi-lobed abdominal flap tunneled through the mons pubis. The flap produced a normal genital contour and has functioned well to seven years follow-up.

Abstract
Advances in endoscopic technology have improved the detection of precancerous bronchial lesions associated with the occurence of proximal squamous cell lung cancer (SCC) in high-risk individuals for broncho-pulmonary neoplasm. The debates and controversies regarding the control and treatment of intraepitelial bronchial lesions is due to the fact that the regression rate of all preneoplastic bronchial lesions is 54%. But the progression to carcinoma in situ or to cancer is significantly higher for severe dysplasia, than for preneoplastic lesions showing lower-grade dysplasia, such as squamous metaplasia and mild or moderate dysplasia. The progression rate to carcinoma in situ or cancer with squamous cells varies between 19% and 46% for patients with severe dysplasia. The diagnosis and resection of pulmonary cancer in incipient stages increases spectacularly the survival rates of the resected patients, by comparison to the non-operated patients.

Abstract
The association between human papillomavirus (HPV) and anal cancer and the similarities between the "transitional zones" within the cervix and anus have raised questions regarding the medical biology of anal cancer. In recent years, increased rates of HPV infection and anal cancer among men have encouraged the medical community to search for causes and ways to identify the less insidious precursor, anal intraepithelial neoplasia. The "alphabet soup" terminology describing anal cytologic findings obtained by Papanicolaou (Pap) tests and the anal histologic findings obtained from biopsy specimens need to be better understood as distinct entities. Risk factors for the development of anal cancer have been identified and should be discussed with patients--especially those infected with human immunodeficiency virus--who have a much higher than normal risk of anal cancer. The anal Pap test has been used by the Northwest Pennsylvania Rural AIDS Alliance to detect potential precursors to cancer and degrees of anal dyplasia in patients with HIV infection. The Alliance has been instrumental in creating guidelines for anal Pap testing and encouraging other medical professionals and clinics to do the same, and these guidelines are provided herein.

Abstract
Lichen sclerosus (LS) is an inflammatory skin disease predominantly affecting the anogenital region. If untreated, progressive sclerosis results in scarring with distortion of the normal architecture. LS occurs more commonly in women than men but may occur in all age groups, including adolescents and prepubertal children. Its exact prevalence is unknown, but estimates range from 1:60 to 1:1000. In this article, LS is discussed in detail with respect to disease management in adults and children, risk of malignancy, and association with other diseases.

Abstract
OBJECTIVE To investigate the pathogenesis, high risk factors, clinical characteristics, methods of diagnosis and treatment, and prognosis of vaginal intraepithelial neoplasia (VAIN). METHODS The clinical data of thirteen cases of VAIN treated in Zhejiang Provincial Cancer Hospital dated Mar. 2002 through Dec. 2008 were reviewed and analyzed retrospectively. RESULTS Twelve of 13 VAIN cases were performed the human papillomavirus (HPV) detection with 92% (11/12) HPV positive rate. None of the cases shown specific clinical manifestation. Among the 13 cases, 6 of them accompanied with cervical cancer, 4 cases with cervical intraepithelial neoplasia (CIN), and 3 cases with vulvar intraepithelial neoplasma (VIN). Five cases synchronously diagnosed with cervical lesion and 3 with vulva lesion were underwent surgery, while the other 5 cases were diagnosed metachronously. Among 8 cases underwent surgery, 1 case with CIN underwent argon plasma coagulation (APC) after surgery, 1 case with the positive edge of VIN underwent APC. During follow up, 1 case with locally advanced cervical cancer underwent radiotherapy again, 3 cases with VAIN received APC, while 1 cervical cancer cases with VAIN received no treatment. The average follow-up time was 25.6 months (range 6-87 months). Two cases died of cervical cancer metastasis. The other 11 cases were normal and still alive. None of them progressed to invasive carcinoma. CONCLUSIONS The main reason of VAIN is HPV infection. There are not specific clinical manifestations, usually diagnosed when reviewing cervical or vulva lesions and rarely progressed to invasive carcinoma. The main treatment of VAIN is surgery with the adjuvant treatment of APC.

Abstract
Invasive tumors (cancers or malignant lesions) typically develop in the setting in which there is the presence of putative non-invasive lesions and the development of these non-invasive lesions frequently precedes the development of cancers. For some organs, such as the oral cavity, cervix and skin, the respective putative pre-invasive lesions can be observed over time and documented to progress to invasive lesions. However, for less readily observable lesions, such as those of the prostate, the progression of the pre-invasive lesions, e.g., prostatic intraepithelial neoplasia (PIN) and prostatic proliferative inflammatory atrophy (PIA) to prostatic cancer are more difficult to document. Thus, for most organ systems, specific pre-invasive neoplastic lesions have been proposed based upon the apparent observations of one or more of the following: 1) microinvasive disease developing from a pre-invasive neoplastic lesion, 2) the general association of the pre-invasive lesion with invasive lesions, 3) the subsequent development of invasive lesions following diagnosis of the pre-invasive lesion, 4) correlations of the molecular features of the putative pre-invasive lesion with the matching invasive lesions, and 5) reductions in the rate of cancer following removal of the pre-invasive lesion. When there are mixtures of pre-invasive lesions with actual cancers in the same case, some of the above specific associations are more difficult to make. Several terms have been used to describe pre-invasive lesions, many of which are now less useful as our knowledge of these lesions increases. It is now commonly accepted that these lesions are a features of the spectrum of neoplastic development and most are accepted as ``neoplastic lesions'' with associated molecular features, even though they may be reversible even if they have mutations in suppressor genes (e.g., p53) or are associated with viral etiologies (e.g., cervical intraepithelial neoplasia). The overall term, "pre-invasive neoplasia", seems to best describe these putative pre-invasive lesions. Thus, terms such as incipient neoplasia should be abandoned. The term "intra-epithelial neoplasia" with an associated grade, which has been developed for pre-invasive neoplastic lesions of the cervix, i.e. cervical intraepithelial neoplasia (CIN), seems to be a terminology that adds consistency across epithelial organs. Thus, adoption of these terms for the additional organ sites of pancreas (PanIN) and prostate (PIN) seems accepted. Less descriptive terms such as the degrees of dysplasia of the oral cavity and bronchopulmonary system and actinic keratosis and Bowen's disease of the skin might be better designated as oral intraepithelial neoplasia (OIN), pulmonary intraepithelial neoplasia (PulIN) and dermal intraepithelial neoplasia (DIN). The etiology of pre-invasive neoplasia is the etiology of the matching cancers. Some obvious initiating factors include exposure to the whole range of ionizing and non-ionizing radiation, tobacco abuse and a broad range of other carcinogens (e.g., benzene). A frequent initiation factor is the setting of long standing continuing damage, inflammation and repair (LOCDIR) which leads to early molecular features associated with neoplasia after about one year. An excellent example of this is ulcerative colitis (UC) in which dysregulation of microsatellite repair enzymes have been documented one year following diagnosis of UC. While the nomenclature, description, diagnosis and etiology of pre-invasive neoplasia has advanced, approaches to therapy of such lesions have not progressed adequately even though it has been identified that, for example, removal of polyps periodically from the colorectum, DCIS from the breast, and high grade CIN from the cervix, results in a reduction in the development of cancers of the colorectum, breast, and cervix, respectively. With the development of more molecularly targeted therapy with fewer side effects, preventive therapies may be more successfully targeted to pre-invasive neoplastic lesions.

Abstract
A case-control study was undertaken to determine the dietary intake of vitamin A in women having abnormal uterocervical cytology. The study groups (87 cases and 82 controls) were drawn from a population of women who received a screening Pap test in the ambulatory health care section of a large municipal hospital center. A subset of cases (with abnormal cytology) were matched to controls for age, ethnicity, socioeconomic status, and parity. Nutrient intake and retinol binding protein concentrations were determined; epidemiological data were also obtained. It was found that the subset of cases with severe dysplasia or carcinoma in situ (CIS) were more likely to have a total dietary vitamin A intake below the pooled median (3,450 IU) and/or a beta-carotene intake below the pooled median (2,072 IU) than were normal controls (p less than 0.05 and p less than 0.025, respectively). Odds ratios revealed approximately a 3-fold greater risk for severe dysplasia or CIS in women with lowered vitamin A or beta-carotene intake. In addition, retinol binding protein was either absent or undetectable in 78.8% of the dysplastic tissue samples, versus 23.5% of the normal tissue samples (p less than 0.005).

Abstract
Aurora kinases play key roles in the transition of G2/M phase by regulating functions of centrosomes and microtubules. Overexpression of Aurora-A, a new oncogene, can induce centrosome amplification, aneuploidy and tumor formation. Aurora kinases are closely associated with breast cancer. In this article, we reviewed the mechanisms of Aurora kinases inducing tumorigenesis of breast cancer via interacting with p53 gene, BRCA1 gene, PTEN/PI3K/AKT pathway, gene polymorphism, estrogen, and so on, analyzed the expression of Aurora kinases in breast cancer and its relationship with prognosis.

Abstract
Anal dysplasia caused by human papillomavirus (HPV) infection is common in the HIV-infected population and is a precursor to squamous cell carcinoma of the anus (SCCA). Herein, we describe our initial experience in assessing the frequency and severity of anal intraepithelial neoplasia (AIN) in a newly formed anal dysplasia clinic in Seattle. During a 7-month period, 150 HIV-positive men were evaluated by digital rectal examination and high-resolution anoscopy (HRA). Forty-seven patients of the 122 patients who underwent biopsy (39%) had biopsy-identified low-grade AIN, and 47 (39%) had high-grade AIN (HGAIN). Two patients with HGAIN were referred for surgical treatment and were further noted to have microinvasive SCCA. No patient reported significant post-HRA biopsy complications. Patient tolerance and acceptance of AIN screening was good, and the majority of those who underwent screening have been adherent to recommended follow-up examinations and treatment. The clinic is expanding rapidly, with excellent community and provider support. We anticipate that the anal dysplasia clinic will enable our institution to participate in emerging HIV- and HPV-related AIN clinical trials.

Abstract
OBJECTIVE To evaluate the etiology, clinicopathological characteristics, treatment and prognosis of VINIII. METHODS Thirty-five patients with VINIII admitted in Cancer Hospital of Chinese Academy of Medical Sciences between 1993 and 2008 were analyzed retrospectively. RESULTS All 35 patients attended to hospital with the symptoms of pruritus vulvae and lumps. Among of them, there were 28 (80%) cases whose lesions presented as multiple plaques, while 7 (20%) cases lesion were monofocal. Fifteen out of 35 cases had coexistent with human papillomavirus (HPV) related lesions, and there were the evidence of HPV in 22 patients whose pathologic sections revealed koilocytes. 34 cases (97%) except one received different types of surgical resections, including wide local resection (14/34), simple vulvectomy (16/34) and simple vulvectomy plus perianal skin resection (4/34), while there two cases shown positive cut-edges and one of them received radiotherapy postoperatively. Four out of the 34 cases recurred locally in 2, 4, 6 and 22 months and received surgical treatment again or laser therapy, respectively. The median follow-up period was 66 months (range 1-166), and none of them were died of the disease itself except one case died of the concurrent cervical cancer. Among 26 cases received the investigation of the quality of life, there were nine cases (35%) suffered from sexual dysfunction after the operation, and one of them received vulvoplasty. CONCLUSIONS VINIII has good prognosis. The development of VINIII may be related to the infection of HPV, because most of them concurrent with HPV diseases. Its primary treatment is surgical resection, while affecting on the quality of life.

Abstract
PURPOSE OF REVIEW The incidence of human papillomavirus (HPV)-related cancers has increased among people with HIV infection compared with the general population. This review will describe recent findings in HPV-associated cancer incidence since the introduction of antiretroviral therapy, HPV/disease prevalence at sites other than cervix and anus, and recent data on screening and treatment of anal intraepithelial neoplasia. RECENT FINDINGS Consistent with high prevalence of anogenital HPV infection, new data on cervical intraepithelial neoplasia and anal intraepithelial neoplasia in HIV-positive men and women show that the incidence of cervical cancer has not declined since the introduction of antiretroviral therapy and that the incidence of anal cancer is rising. Several studies also highlight high rates of HPV infection and HPV-associated disease at sites other than the cervix and anus, including the penis and the mouth. Treatment methods for anal intraepithelial neoplasia have been described and show reasonable efficacy. SUMMARY New data imply that the problem of HPV-related cancers will not decline among HIV-positive men and women in the antiretroviral therapy era, highlighting the need to perform studies to determine if screening and treatment of anal intraepithelial neoplasia will prevent development of anal cancer. Recent data show progress in both these areas.

Abstract
Genomic instability is one of the main characteristics of malignant tumors, including HPV-induced cervical cancer. The aim of this study was to explore the use of assessing chromosome aberrations (CA) in peripheral blood lymphocytes as a biomarker for genomic instability in high-risk HPV-infected women with high-grade squamous intraepithelial lesions (HGSIL). A total of 120 women were recruited for this study, following cytology/colposcopy evaluation and HPV DNA detection. The study groups consisted of 30 HPV(+) women with histologically confirmed cervical intraepithelial neoplasia grade 2/3 and 30 HPV(+) women with carcinoma in situ (CIS). Two control groups, including 30 women HPV(-) and 30 women HPV(+), were recruited among women who were reported as cytology negative. Lymphocyte cell cultures were established for 52 hr, and 100 complete metaphase cells were evaluated per subject for CA analysis. The results show that women with CIS had significantly higher frequencies of both aneuploidy (0.67 +/- 0.20 vs. 0.14 +/- 0.08, P = 0.020) and tetraploidy (0.88 +/- 0.23 vs. 0.17 +/- 0.08, P = 0.013) in comparison with HPV(-) controls. These findings suggest the usefulness of peripheral blood lymphocytes to detect genomic instability associated with HPV-induced HGSIL.

Abstract
Advances in imaging technology and engineering have now permitted functional integration of a confocal endomicroscope into the distal tip of a conventional video colonoscope enabling imaging of the surface epithelium and the underlying lamina propria during ongoing video endoscopy. For the first time, the endoscopist is now able to resolve the surface and subsurface mucosa at cellular resolution in vivo and in real time. A new era in endoscopic imaging has therefore begun - histoendoscopy. In addition to providing a high-accuracy in vivo optical biopsy tool for the differentiation between benign hyperplasia, intra-epithelial neoplasia and carcinoma in sporadic cohorts, endomicroscopy with targeted biopsies has now been shown to increase the yield of intra-epithelial neoplasia complicating ulcerative colitis. Furthermore, recent data examining endomicroscopic molecular ex vivo imaging using anti-CD44v6 antibody has identified aberrant crypt foci based on their surface molecular expression. Receptor overexpression in vivo in humans may, in the near future, be exploited for the diagnosis of inflammation, neoplasia and in predicting targeted molecular therapy. Endomicroscopy will be key to this immuno-imaging interface. Within the present review, we discuss the current clinical evidence in support of confocal endomicroscopy and explore the new diagnostic possibilities for this technology.

Abstract
Testicular cancer (TC) is a rare form of cancer, accounting for 1% of all new cancer cases in Canadian males. TC is the most common malignancy among young men, aged 25-34 yr old. Over previous decades, the incidence of TC has increased in many Western countries. Countries with a sufficiently long period of cancer registration, such as Denmark, document this trend back to the first half of the 20th century. The etiology of TC remains poorly understood. Most of the established risk factors are likely related to in utero events, including some factors that are purported to be surrogate measures for exposure to endogenous estrogens. The correlation of TC with other testicular abnormalities and with pregnancy factors led to the proposal that these conditions are a constellation of sequelae of impairment of testicular development called testis dysgenesis syndrome. There is some limited evidence suggesting that exposure to pharmacological estrogens may contribute to some cases of TC. There is currently no compelling evidence that exposure to environmental estrogenic or other hormonally active substances is contributing to the rise in TC incidence observed in Western nations over the last several decades; however, this question has not been extensively studied. The (1) rarity of this condition in the population, (2) long lag time between the presumed sensitive period during fetal development and clinical appearance of the condition, and (3) lack of a good animal model to study the progression of the disease have greatly hindered the understanding of environmental influences on TC risk.

Abstract
BACKGROUND Although the associations with cigarette smoking have been explored extensively for invasive breast cancer, the relation to in situ cancer has not previously been examined in depth. METHODS We analyzed data from a population-based case-control study of women living in Wisconsin, Massachusetts, and New Hampshire. Eligible cases of incident breast carcinoma in situ were reported to statewide registries in 1997-2001 (n = 1878); similarly aged controls (n = 8041) were randomly selected from population lists. Smoking history and other risk factor information were collected through structured telephone interviews. Odds ratios (ORs) and 95% confidence intervals (95% CIs) were calculated from logistic regression models adjusting for potential confounders. RESULTS In multivariate models, the OR for breast carcinoma in situ among current smokers was 0.8, compared with never-smokers (95% CI = 0.7-1.0). Risk estimates increased towards the null with greater time since smoking cessation. Odds ratios were also less than 1.0 among women who initiated smoking in adolescence (OR = 0.8) or after a full-term birth (OR = 0.7), relative to women who never smoked. The reduced odds ratios associated with current smoking were strongest among women with annual screening mammograms (OR = 0.7; 95% CI = 0.6-0.9). Odds ratios were not less than 1.0 among current smokers without a recent screening mammogram (1.3; 0.9-2.0). CONCLUSIONS Our findings suggest an inverse association between current smoking and risk of breast carcinoma in situ among women undergoing breast cancer screening.

Abstract
The frequent association of human papillomavirus infection with preinvasive and invasive cancers of the cervix has led to speculation that the viruses may be involved in the neoplastic process. We have carried out some epidemiological studies of the prevalence of human papillomavirus infection in the female genital tract to evaluate more fully the oncogenic potential of these viruses in the cervix. A non-invasive method of detecting the virus has been developed for this purpose using DNA hybridization of cervical scrapings. The technique has been used to carry out prospective studies of patients with cervical intraepithelial neoplasia (CIN) and to investigate infection in women treated by laser therapy for CIN. We have also studied women with normal cervices to determine the prevalence of human papillomaviruses in the normal population. Further studies have involved the investigation of the effect of interferon on virus replication and epithelial proliferation in women with CIN III.

Abstract
The first evidence for the oncogenic potential of human papillomaviruses (HPVs) was obtained through the study of epidermodysplasia verruciformis (EV). This rare skin disease is characterized by disseminated, refractor, pityriasis versicolor-like lesions as well as flat wart-like lesions, and by the development of skin carcinomas in about 30% of the patients. EV is a multifactorial disease involving genetic, immunological and extrinsic (actinic) factors, in addition to infection with specific HPV types. A number of HPVs (at least 15 types) have been characterized in benign EV lesions. HPV DNA sequences are regularly detected in EV carcinomas but, in contrast to benign lesions, the types associated with cancers are usually restricted to HPV-5 and, less frequently, HPV-8, an HPV-5-related type. HPV-5 genomes are usually found as free monomeric or oligomeric DNA molecules in EV carcinomas, and frequently contain deletions. This is in contrast with HPV DNA sequences in genital cancers, which are often integrated into the host DNA. Evidence for the transcription of HPV-5 genomes in primary and metastatic EV carcinomas has recently been obtained. The available data indicate that HPV-5 and some HPV-5-related types have an oncogenic potential and play a role in the malignant transformation of EV lesions. Infection by these HPVs must be considered a major risk factor for the development of cancers in EV patients. EV HPV DNA sequences have only rarely been detected in premalignant or malignant lesions of the skin in the general population. This further stresses the role of genetic, immunological and extrinsic factors in the abnormal susceptibility of EV patients to a set of specific HPV types.

Abstract
While much is known about the natural history of cervical human papillomavirus (HPV) infection and its consequences, including cervical intraepithelial neoplasia and cervical cancer, relatively little is known about the natural history of anogenital HPV infection and diseases in men. In part this reflects difficulties in penile sampling and visual assessment of penile lesions. Anal HPV infection and disease also remain poorly understood. Although HPV is transmitted sexually and infects the genitals of both sexes, the cervix remains biologically more vulnerable to malignant transformation than does the penis or anus in men. An understanding of male HPV infection is therefore important in terms of reducing transmission of HPV to women and improving women's health. However, it is also important due to the burden of disease in men, who may develop both penile and anal cancer, particularly among HIV-positive men who have sex with men. Improved sampling techniques of the male genitalia and cohort studies in progress should provide important information on the natural history of anogenital HPV infection and disease in men, including risk factors for HPV acquisition and transmission. The impact of HPV vaccination in women on male anogenital HPV infection will also need to be assessed.

Abstract
OBJECTIVE To evaluate the biological behavior and treatment method for the breast atypical lobular hyperplasia (ALH) and breast lobular carcinoma in situ (LCIS). METHODS Seventeen cases of ALH and thirty-five cases of LCIS were reviewed from July 1982 to January 1996. All cases were followed by physical examination, mammography and B-ultrasound for an average of 146.6 months (range, 3 - 257 months). RESULTS Most cases of ALH and LCIS occurred before menopause (about 69.2%). Fifty-two cases of ALH and LCIS were occasionally verified pathologically after surgery for benign diseases. The microcalcification with ALH and LCIS had been detected in 25 cases, accounted for 48.1%. Eight cases of ALH/LCIS became invasive carcinoma. There were 5 cases in the same breast, 3 cases in the contralateral breast; The subsequent breast cancer occurred longer than nine years after ALH/LCIS was diagnosed. The family history of breast carcinoma and ovary carcinoma occurred in 4 cases of breast carcinoma, accounted for 50%, but it was no significant (P > 0.05). Also, there was no difference between LCIS and ALH, which occurred the breast carcinoma (P > 0.05). CONCLUSION The excisional biopsy might be necessary to ALH and LCIS.
