The best way to prevent cervical dysplasia is to get the HPV vaccine. Consult your doctor to know if you meet all criteria for the vaccine. For best results, girls and boys between the ages of 9 and 26 should get vaccinated before becoming sexually active.
However, vaccination can be helpful after onset of sexual activity and up to age Consult your doctor to discuss the vaccine criteria and if you should be vaccinated.
Treatment for cervical dysplasia will depend on the degree of abnormal cells and your medical history. Most mild cases will clear up without treatment. Your doctor may suggest getting a pap test every 6 to 12 months, instead of every 3 to 5 years. Instances of moderate or severe cervical dysplasia could require immediate treatment.
Options include:. Early diagnosis and prompt treatment cures most cases of cervical dysplasia. Once treated, cervical dysplasia can return. People who have severe cervical dysplasia, high-risk HPV, or whose condition goes untreated could develop cervical cancer. This article was contributed by: familydoctor.

Human papillomavirus HPV is a common sexually transmitted infection that can cause genital warts and certain types of cancer. A Pap smear is a medical exam used to determine if a woman has cervical cancer. Visit The Symptom Checker. Dysplasia is graded as follows [ 2 ]. Negative for dysplasia: Inflamed or regenerating mucosa with normal maturation of glandular epithelium.
Mitotic figures and histological features of regeneration are confined to the lower half of the glands Fig. Indefinite for dysplasia: When epithelium has features suggestive of dysplasia but changes are insufficient to be unequivocally diagnostic Fig. Positive for dysplasia—low-grade dysplasia LGD : The glands lined by cells having hyperchromatic, enlarged nuclei with preserved polarity, mucinous differentiation is decreased, and dystrophic goblet cells.
Atypia may focally reach the surface Fig. Positive for dysplasia— high-grade dysplasia HGD : The glands lined by atypical cells having prominent nuclear pleomorphism with hyperchromatic often rounded nuclei that are stratified throughout the cells.

Also, UC predisposes to a higher incidence of several other synchronous colorectal cancers.
CRC is a fatal long-lasting outcome of chronic UC and is the result of a complex series of molecular and histological abnormalities of the intestinal lining characterized by a gland of variable differentiation and lined by anaplastic cells having large, hyperchromatic nuclei and prominent nucleoli with prominent mitotic activity often with atypical forms.
CRC is graded as follows:. Grade 1: Composed predominantly of well-formed glands lined by anaplastic cells, in a desmoplastic stroma Fig. Grade 2: Less well-formed glands with focal cribriform architecture Fig. Grade 3: Tumor grows in solid sheets with no distinct gland formation Fig.

Ulcerative colitis is a type of inflammatory bowel disease in which there are relapsing and remitting episodes of inflammation confined to the mucosa of the colon. It almost always involves the rectal area and may spread proximally and in a continuous manner to occupy other parts of the colon.
The Mayo scoring system can also be used to assess disease severity and monitor patients during therapy [ 3 ]. Scores vary from 0 to 12 and higher score demonstrating increased severity of the disease. Evaluation of a patient with suspected ulcerative colitis serves to exclude other causes of colitis, establish the identification of UC, and to determine the degree of involvement and grades of dysplasia. The likelihood and timing of colectomy rely on the area involved and grades of dysplasia or carcinoma at presentation [ 4 , 5 ].
Individuals with the disease have greater chances to develop colonic carcinoma. The risk of carcinoma appears to be highest in patients with pancolitis, while those with the involvement of rectum and rectosigmoid areas are probably not at greater risk of CRC, regardless of the duration of disease [ 6 ]. The CRC risk starts to rise 8 to 10 years after the commencement of disease in patients with pancolitis [ 7 , 8 ]. Other factors that are related to an increased risk of cancer include endoscopic and histological degree of inflammatory reactions, presence of sporadic colorectal cancer in first degree relatives doubles the risk , postinflammatory pseudopolyps twofold increased risk , and the presence of primary sclerosing cholangitis fourfold increased risk [ 9 , 10 ].
Dysplasia in UC is preceded by a long-standing chronic inflammatory reaction and can be established at distant sites from cancer. In contrast, dysplasia in sporadic colon cancer is usually associated with a discrete polyp without inflammation. The purpose of the majority of surveillance plans has been the recognition of dysplasia, which is related to greater chances of developing carcinoma [ 11 , 12 ]. There are also facts that in patients who undergo surveillance, cancers are likely to be diagnosed at the initial stage, and likewise, these patients have a better outcome.
Shivakumar et al. In their prospective study from an academic hospital setting, patients with UC at high risk of CRC were offered screening by magnifying chromocolonoscopy, and the frequency of neoplastic lesions was assessed. They found that on initial screening, low-grade dysplasia LGD was seen in five Of these three, one accepted proctocolectomy immediately, one underwent surgery for adenocarcinoma, and one refused surgery.
Twelve follow-up colonoscopies in nine patients revealed three new LGD. They concluded that high-grade dysplasia and subsequent adenocarcinoma can be detected with careful follow-up in Indian patients with long-standing UC, but acceptance of surveillance and subsequent therapy are suboptimal.
The first report of intestinal cancer occurrence in IBD was published over 80 years ago. Since then, numerous studies have addressed this issue, but the true risk of malignancy remains uncertain. Current screening endoscopy protocols are primarily based on white light endoscopy WLE and random biopsies.
On account of these screening techniques, sufficient evidence is available in the literature today suggesting a greater risk of colonic cancer in subjects having long-standing ulcerative colitis [ 15 , 16 ]. According to available data, patients who undergo cancer surveillance are more likely to be diagnosed at the initial stage, and therefore, these patients exhibit better outcomes as compared to patients diagnosed at an advanced stage.

The general principle at our hospital is that all histopathology slides, including biopsies from colonoscopies performed elsewhere, are examined by at least two experienced gastrointestinal pathologists at our institution in order to confirm dysplasia.
Flat dysplasia was defined as the absence of a raised mass, lesion, or polyp in endoscopy and pathology reports. Raised dysplasia was defined as a discrete raised lesion located in an area involved by either quiescent or active colitis adenoma like mass that was endoscopically resected with biopsy confirmation of dysplasia.
Raised lesions at endoscopy that were felt to be irregular or un-amenable to excision and hence more suggestive of mass or plaque-like lesion i. DALM were excluded as these patients were referred for colectomy. Surveillance for dysplasia in our clinic has followed the initial ACG Practice Guidelines since Chromoendoscopy was not used for cancer surveillance at our institution.
Surgical reports and findings during colectomy were evaluated. Our protocol to evaluate colectomy specimen at our institution is to do sampling every 10 cm for cases without dysplasia on preoperative biopsy, and sampling very 5 cm for cases with dysplasia on preoperative biopsy.
Visible lesions are always sampled for both cases. Study outcomes were defined similar to a previous study. The time of last surveillance colonoscopy without any AN detected or colectomy performed for any indication was chosen as the time point at which data was censored. The secondary outcome was the risk of progression to AN depending on the location of dysplasia proximal vs. LGD was considered proximal if it occurred proximal to the splenic flexure.
Descriptive statistics were computed for all factors. These include medians, interquartile range IQR , range or mean and standard deviation for quantitative variables and frequencies and percentages for categorical factors. Normally distributed continuous variables were analyzed by using a t test, and continuous variables that were not normally distributed were analyzed by using the nonparametric Wilcoxon rank sum test.
Comparisons between categorical variables were performed by Pearson's chi-square test. In order to determine if the diagnosis of AN tended to occur at a certain time following the diagnosis of LGD, the occurrences of AN for time intervals of 2 years were estimated in the presence of colectomy as a competing risk. The log-rank test was used to compare the Kaplan—Meier curves.
Censoring was performed at the time of proctocolectomy, or death. The basic demographic and clinical information is summarized in Table 1. There were no statistically significant differences in the clinical parameters except for 5-ASA use in the proximal and distal locations of dysplasia Tables 1 and 2. Also, only 3 patients were on biologics in our cohort; 2 in the distal and 1 in the proximal colon. Of the patients, 65 patients had raised LGD morphology, while the remaining 37 had flat morphology.
The initial location of dysplasia was in the proximal colon in 47 and distal colon in 55 patients. Of the patients with LGD, 5 4. In the entire cohort, 26 patients had recurrence of LGD at least once during follow-up. Of the 5 patients who progressed to AN, in 4 patients, the initial dysplasia was located in the distal colon at colonoscopy. Of these 4 patients, 3 progressed to AN in the distal colon all HGD: 2 flat and 1 raised and 1 patient had AN cancer in the proximal colon.
For the other patient who developed AN, the initial dysplasia was in the proximal colon and AN cancer also occurred in the proximal colon. In 2 of the 5 patients, AN was noted in colectomy after surgery while in 3 patients AN was noted on colonoscopies after a median follow-up time of 27 months. Another patient underwent surgery for HGD detected in the proximal colon 27 months after the initial LGD diagnosis and the examination of surgical specimen confirmed carcinoma in the proximal colon.
The third patient had AN detected on colonoscopy 60 months after initial diagnosis of LGD and was followed for 18 months with the disappearance of HGD on subsequent surveillance colonoscopic biopsies. The cancer staging was T2N1M0 in both the patients with cancer. Two of the 65 3.
Patients with distal colonic flat dysplasia had the highest rate for AN, which was 3. During this time, regular surveillance colonoscopy was performed, with a mean of 5. The risk for AN per person-years for each 2-year time-intervals from the diagnosis of LGD is summarized in Table 3.
A total of 19 patients underwent colectomy for dysplasia or dysplasia and steroid dependent disease, while one patient underwent colectomy for medically refractory disease. The patient who underwent colectomy for medically refractory disease did not have AN.
Of the 15 patients who had flat LGD distal colon and steroid-dependent disease, 1 patient had AN in the distal colon in colectomy, 8 did not have any evidence of LGD, while 6 patients had LGD in the colectomy specimen. Table 4 details the results of univariate analysis. Location of dysplasia in the colon was not associated with the risk of progression to AN with a hazard ratio HR of [3. Patients with LGD with flat morphology in the distal colon were however more likely to progress [ HR 3.
Multivariable testing could not be performed because of the limited number of patients. This is because of the fact that the natural history and progression of LGD to AN are variable in studies published thus far. All the previous studies included at least in part, patients who underwent surveillance colonoscopies before the implementation of the ACG surveillance guidelines which recommend obtaining 4-quadrant biopsies every 10 cm throughout the colon.
The association of type flat vs. The results of the analysis suggested that the rate of progression of LGD to AN was low and that this risk increased with time.
Dysplasia in the distal colon with a flat morphology was more likely to progress to AN. Even in the earlier studies, the incidence of CRC decreased over time. Our study demonstrates that in UC patients with raised LGD, as described in this study, after complete endoscopic removal surveillance colonoscopy can be a consideration. Differences in the biology for dysplasia in the proximal and distal colon may explain the rapid progression of distal LGD to AN.
While current ACG guidelines prompt consideration of surgery in patients with flat LGD to prevent progression to a higher grade of neoplasia 19 these recommendations remain relatively unclear. The rate of progression of LGD to AN was low in our study and for patients who underwent colectomy for LGD, 8 patients did not have any dysplasia in the colectomy specimen.
Two patients had LGD in the proximal and distal colon and the other patient had only in the distal colon. These findings suggest that the management of flat LGD needs to be individualized and other factors need to be incorporated into the decision-making. Thus, flat LGD in the distal colon in the presence of other risk factors may support surgery rather than surveillance.
On the other hand, in the absence of other risk factors especially when flat LGD is located in the proximal colon, colonoscopic surveillance may be considered.
It is also important to emphasize to the patient that surgery is the treatment modality that can eliminate the risk of cancer whereas colonoscopic surveillance requires frequent procedures, and hence compliance and motivation, with an ongoing risk for development of AN.
Further, when there are additional reasons for surgery, i. The particular strength of this study is the inclusion of data for a large number of patients with UC with LGD who underwent surveillance.
There are, however, certain limitations. With the low number of observed events of progression, univariable associations were difficult to detect, and estimated hazard ratios exhibited wide confidence intervals.
With the number of variables included in the univariable analyses, there is also a possibility that some of the significant associations may have occurred by chance.
Similarly, it is possible that we lacked the power to detect a statistical significance for other associations. The study population was recruited from a tertiary care center, and may hence have led to a referral bias.
Thus, there is a potential for incomplete follow-up as many patients may undergo subsequent follow-up locally after initial evaluation and the possibility that the referral was made for the dysplasia. In order to minimize these potential problems, we included only patients who had a continued follow-up at our institution with at least 2 or more surveillance colonoscopy examinations, excluding patients who were lost to follow-up or were referred with a diagnosis of dysplasia.
The median number of colonoscopies in our cohort of patients was 5, which suggests that patients were followed-up regularly at our institution. The retrospective nature of this study could additionally influence the results.
