Even though a malignant tumor during pregnancy is very rare it occurs in 0.02-0.1%. With the tendency in society to postpone childbirth to an older age, there will be more cancers diagnosed during pregnancy. The coincidence of malignant disease with pregnancy leads to an enormous emotional burden to the patient, the couple and the medical staff. Surgery for malignant tumors during pregnancy seems to be save. Radiotherapy on the other hand should be avoided. Chemotherapy is regarded to be save during the second and third trimester but it should not be applied during the first trimester because of its teratogenic effects. The most frequent malignant disorders during pregnancy are
cervical cancer
, breast cancer, melanoma and
Hodgkin lymphoma
. We discuss possible treatment options for breast cancer and gynecological tumors during pregnancy. Ovarian Cancer is a rare event during pregnancy. Because of frequent prenatal visits most of them are diagnosed at an early stage, with good prognosis. In case of advanced stage of ovarian cancer chemotherapy besides surgery is necessary. The former usually is preferred as monotherapy during pregnancy. To treat breast cancer during pregnancy a mastectomy with axillary lymphonodectomy is necessary to avoid radiotherapy. Indications for chemotherapy are the same as for not pregnant patients. Usually AC with and without 5-FU is used. For invasive cervical cancer surgery or radiotherapy +/- chemotherapy is indicated after induced abortion or cesarean section. Early termination of pregnancy is of no survival benefit to the mother in case of breast cancer and ovarian cancer. In these cases systemic therapy during pregnancy and delivery at 34 weeks is recommended.

In the United States, oral cancer accounts for more deaths annually than
cervical cancer
, leukemias, or
Hodgkin's lymphoma
. Studies have shown that aberrations of chromosome 18q develop with tumor progression and are associated with significantly decreased survival in head and neck cancer patients. The G-protein-coupled receptor, galanin receptor 1 (GALR1), maps to this region of chromosome 18q. Although the role of GALR1 has been well characterized in neuronal cells, little is known regarding this receptor in non-neuronal cells. In this study, the expression, mitogenic function, and signaling mechanism of GALR1 are investigated in normal and malignant oral epithelial cells. mRNA expression was determined via reverse transcriptase-PCR. Protein quantification was done via immunoblot analysis and enzyme-linked immunosorbent assay. For functional and signaling studies, an inhibitory antibody was generated to the N-terminal ligand binding domain of GALR1. GALR1 protein and mRNA expression and GAL secretion were detected at variable levels in immortalized human oral keratinocytes and human oropharyngeal squamous cell carcinoma cell lines. Upon competitive inhibition of GALR1, proliferation was up-regulated in immortalized and malignant keratinocytes. Furthermore, studies with the inhibitory antibody and U0126, the MAPK inhibitor, show that GALR1 inhibits proliferation in immortalized and malignant keratinocytes by inactivating the MAPK pathway. GALR1s inhibitory effects on proliferation in epithelial cells raises the possibility that inactivation or disregulation of this receptor can lead to uncontrolled proliferation and neoplastic transformation.

With fewer patients now succumbing to infectious complications of AIDS, other HIV-related morbidities such as malignancies have become increasingly important. Apart from Kaposi's sarcoma, non-Hodgkin's lymphoma, and
cervical cancer
, which are considered as AIDS-defining, several additional cancers, referred to as non-AIDS-defining cancers, are also statistically increased in HIV-infected persons. These include
Hodgkin's disease
, anal carcinoma, lung cancer, nonmelanomatous skin cancer, and testicular germ cell tumors, among others. However, the types of cancer observed at an increased frequency and the relative risks reported vary widely among studies. Although immunosuppression is consistently associated with an increased risk of AIDS-related malignancies, the role of immunosuppression in the pathogenesis of non-AIDS- defining cancers is controversial. Although data regarding the optimal management of these cancers are lacking, current studies suggest that patients with HIV-associated malignancies should be treated with similar approaches to those of their counterparts in the general population.

The survival of persons with AIDS (PWA) has recently improved because of better antiretroviral therapies. Similarly, the prognosis of cancer has also improved. To determine if survival in PWA with cancer has also improved, we compared cancer survival in adults with and without AIDS using data from New York City from 1980 through 2000. Analyses were made for AIDS-related cancers (Kaposi sarcoma, non-
Hodgkin lymphoma
[NHL], and
cervical cancer
) and for 8 non-AIDS-related cancers (lung, larynx, colorectum, anus,
Hodgkin lymphoma
, breast, prostate, and testis). Death hazard ratios compared survival in PWA with cancer with that in cancer patients without AIDS, adjusted for age, sex, race, and calendar-time of cancer occurrence. The 24-month survival rate of PWA with cancer (9015 AIDS cancers and 929 non-AIDS-related cancers of 8 types) improved significantly for most cancer types. By 1996 through 2000, the 24-month survival rate in PWA was 58% for Kaposi sarcoma, 41% for peripheral NHL, 29% for central nervous system NHL, and 64% for
cervical cancer
. For non-AIDS-related cancers, survival of PWA was lowest for lung cancer (10%) but was >50% for most other cancer types. In 1996 through 2000, significant differences in survival between cancer patients with and without AIDS still remained for
Hodgkin lymphoma
and lung, larynx, and prostate cancers. We conclude that recent improvements in AIDS and cancer care have greatly narrowed the gap in survival between cancer patients with and without AIDS. Clinicians should be encouraged by the improving prognosis and be diligent about detecting and treating cancer in PWA.

The role of 2-[fluorine 18]fluoro-2-deoxy-D-glucose (FDG) positron emission tomography (PET) in combination with computed tomography (CT) in the evaluation of pelvic malignancies has been rapidly growing in recent years. FDG PET has proved to be valuable in the evaluation of a variety of pelvic malignancies, including colorectal cancer, uterine
cervical cancer
, ovarian cancer, endometrial cancer, and non-
Hodgkin lymphoma
. However, a number of pitfalls are commonly encountered at FDG PET, including normal physiologic activity in bowel, ovaries, endometrium, and blood vessels and focal retained activity in ureters, bladder diverticula, pelvic kidneys, and urinary diversions. The use of an in-line FDG PET-CT system, with special attention given to proper patient preparation and scanning protocol, often provides valuable information to help localize and define disease and avoid potential diagnostic pitfalls.

The Hmong represent a unique new Southeast Asian immigrant group to the U.S. Approximately 169,000 Hmong reside in the U.S., primarily in California, Minnesota, and Wisconsin. Previous studies of cancer in this population have indicated that Hmong experience an elevated risk of gastric, hepatic, cervical, and nasopharyngeal cancers and experience a reduced risk of breast, prostate, lung, and colorectal cancers. Approximately 65,000 Hmong live in California, where there has been a population-based cancer registry since 1988, and the authors used these data to calculate age-adjusted cancer incidence rates and to examine disease stage and tumor grade at diagnosis. Changes in rates during the period studied also were evaluated. These rates and proportions were compared with rates among the non-Hispanic white (NHW) and Asian/Pacific Islander (API) populations of California. Between 1988 and 2000, a total of 749 Hmong in California were diagnosed with invasive cancer, and the age-adjusted rate of cancer for the Hmong was 284 per 100,000 population, compared with 362.6 and 478 per 100,000 in the API and NHW populations, respectively. The age-adjusted incidence rates of cancer in the Hmong were elevated for hepatic, gastric, cervical, and nasopharyngeal cancers and for leukemia and non-
Hodgkin lymphoma
(NHL). Rates were lower in the Hmong for colorectal, lung, breast, and prostate cancers. For gastric cancer and lung cancer, age-adjusted rates increased between 1988 and 2000 in the Hmong, although breast cancer incidence declined.
Cervical cancer
incidence increased, rates of NHL were declining, and rates for colorectal cancer remained steady between 1988 and 2000. The Hmong experienced later disease stage at diagnosis than other API and generally poorer grade of disease at diagnosis. Hmong experienced lower overall invasive cancer incidence rates than API or NHW populations in California. However, they experienced higher rates of hepatic, gastric, cervical, and nasopharyngeal cancers; and, for most types of cancer, they were diagnosed in a later disease stage.

U.S. studies have reported an increased risk of esophageal and some other cancers in dry cleaners exposed to tetrachloroethylene. We investigated whether the U.S. findings could be reproduced in the Nordic countries using a series of case-control studies nested in cohorts of laundry and dry-cleaning workers identified from the 1970 censuses in Denmark, Norway, Sweden, and Finland. Dry-cleaning work in the Nordic countries during the period when tetrachloroethylene was the dominant solvent was not associated with an increased risk of esophageal cancer [rate ratio (RR) = 0.76; 95% confidence interval (CI), 0.34-1.69], but our study was hampered by some unclassifiable cases. The risks of cancer of the gastric cardia, liver, pancreas, and kidney and non-
Hodgkin lymphoma
were not significantly increased. Assistants in dry-cleaning shops had a borderline significant excess risk of
cervical cancer
not found in women directly involved in dry cleaning. We found an excess risk of bladder cancer (RR = 1.44; 95% CI, 1.07-1.93) not associated with length of employment. The finding of no excess risk of esophageal cancer in Nordic dry cleaners differs from U.S. findings. Chance, differences in level of exposure to tetrachloroethylene, and confounding may explain the findings. The overall evidence on bladder cancer in dry cleaners is equivocal.

Condylomata acuminata have been shown to increase the risk of anogenital cancers. However, previous studies have been of limited sample size and/or short follow-up duration, which prevent precise estimates of long-term excess risk, especially for specific cancer sites. We estimated the risk of specific cancers in a large cohort of hospitalized patients with condylomata acuminata, as recorded in the Swedish Inpatient Register between 1965 and 1999. Altogether, 10,971 patients (1,685 men and 9,286 women) were followed through 1999 for a median of 13 years. The standardized incidence ratio (SIR)--the ratio of the observed number of cancers to the number expected on the basis of the incidence in the Swedish population at large--was used as a measure of relative risk. After excluding the first-year of follow-up, we observed 43 cases of anogenital cancer in women, and 7 cases in men. Risks were elevated for cancers of the vulva (N = 13, SIR = 10.2, 95% confidence interval (CI) = 5.4-17.4), vagina (N = 4, SIR = 12.0, 95% CI = 3.3-30.7) and penis (N = 5, SIR = 21.9, 95% CI = 7.1-51.2). There was a moderate excess risk of
cervical cancer
in situ (N = 259, SIR = 1.9, 95% CI = 1.7-2.1), but not invasive cervical cancer. Excess risks of esophageal, buccal cavity, nonmelanoma skin, lung and bladder cancers, and
Hodgkin
and non-
Hodgkin lymphoma
, were also observed in both men and women. In conclusion, condylomata acuminata are strongly associated with increased risk of cancers of the vulva, vagina, penis and anus, as well as some nonanogenital malignancies, but not invasive cervical cancer.

A large body of epidemiologic evidence exists for exploring causal associations between cancer and trichloroethylene (TCE) exposure. The U.S. Environmental Protection Agency 2001 draft TCE health risk assessment concluded that epidemiologic studies, on the whole, support associations between TCE exposure and excess risk of kidney cancer, liver cancer, and lymphomas, and, to a lesser extent,
cervical cancer
and prostate cancer. As part of a mini-monograph on key issues in the health risk assessment of TCE, this article reviews recently published scientific literature examining cancer and TCE exposure and identifies four issues that are key to interpreting the larger body of epidemiologic evidence: a) relative sensitivity of cancer incidence and mortality data ; b) different classifications of lymphomas, including non-
Hodgkin lymphoma
; c) differences in data and methods for assigning TCE exposure status ; and d) different methods employed for causal inferences, including statistical or meta-analysis approaches. The recent epidemiologic studies substantially expand the epidemiologic database, with seven new studies available on kidney cancer and somewhat fewer studies available that examine possible associations at other sites. Overall, recently published studies appear to provide further support for the kidney, liver, and lymphatic systems as targets of TCE toxicity, suggesting, as do previous studies, modestly elevated (typically 1.5-2.0) site-specific relative risks, given exposure conditions in these studies. However, a number of challenging issues need to be considered before drawing causal conclusions about TCE exposure and cancer from these data.
