“I have been advised by my physician that I must undergo a course of chemotherapy on my esophagus. This advice seems persuasive to me. I regret having had to cancel so many engagements at such short notice,” Hitchens said.

He is well-known for his prolific consumption of alcohol and cigarettes. It was reported that the chain-smoking Hitchens gave up smoking cigarettes in 2008, though a profile piece in the Washington Post earlier this month showed that he was still indulging in the habit. In 2003 he famously quipped that his daily intake of alcohol was enough “to kill or stun the average mule.”

Hitchens, once a darling of the left, famously underwent an ideological shift in recent years, especially after 9/11, that saw him support the Iraq war and lose the support of many of his former admirers.

Hitchens became an American citizen in 2007. He currently lives in Washington, D.C., with his wife Carol.

Funny lady Jennifer Saunders, most famous perhaps for her role as PR agent Edina Monsoon in ‘Absolutely Fabulous’ and for her comedy routines with partner Dawn French in ‘French & Saunders’, has been fighting breast cancer for the past eight months, it is being reported.

According to reports, Jennifer underwent a lumpectomy, chemotherapy and radiotherapy. A friend told the Daily Mail: “Jennifer’s treatment finished in June. She is very thankful that she has been given the all-clear and is feeling in very good spirits.”

News of the comedienne’s battle with breast cancer came as a shock to many as the news was only reported after Jennifer was seen public wearing a wig and a bandana. After speculation began to grow, Jennifer’s spokesperson confirmed the news. Jennifer does not, reportedly, want to discuss her battle with breast cancer in any public form.

Other celebrities who have been diagnosed with breast cancer include Christina Applegate, Kylie Minogue , Maura Tierney, ‘Sex and the City’ actress Cynthia Nixon and Sheryl Crow.

The drug is the first conjugated monoclonal antibody to be reviewed by the FDA and has realistic chances to be approved in some breast cancer patients by the regulator given the medicine’s strong trial results, analysts said.

T-DM1, which was developed by Roche’s unit Genentech and Immunogen Inc.,works differently from traditional cancer treatments as the medicine links a monoclonal antibody and a cytotoxic. This makes sure that only cancerous cells are destroyed, unlike in chemotherapy that also kills healthy cells.

Roche said that it has submitted a biologics licence application for the treatment of people with advanced HER2-positive breast cancer who have previously received multiple HER2-targeted medicines and chemotherapies.

The submission is based on phase II data which showed T-DM1 shrank tumours in one-third of women who had received on average seven prior medicines for advanced HER2-positive breast cancer. Roche is continuing with T-DM1 trials.

Base on the study, the research found that people with BMI 18.5 kg/m2 and above there was a continuous and positive association between high BMI and all-cancer mortality. Compared with persons with a normal weight, the relative risk for cancer-related mortality was 1.06 (95% confidence interval [CI], 1.00 – 1.12) for those who were overweight and 1.21 (95% CI, 1.09 – 1.36) among obese persons.

In addition, the positive association reported between BMI and all-cancer mortality was particularly pronounced breast cancer (in women 60 years or older), colon cancer, ovarian cancer, prostate cancer, cervical cancer, and leukemia.

Although the mean BMI values have increased in many North American and European populations during the past 30 years, those for Asian populations have generally lagged behind, explains Dr. Renehan.

“However, with a large denominator for all-site cancers in the Asia-Pacific region (6.2 million vs 3.4 million for Europe and 1.6 million for North America), the population impact number (ie, numbers of cases attributable to excess bodyweight) might be substantial,” he writes.

Higher Risk for Mortality

In this study, Christine L. Parr, PhD, from the Institute of Basic Medical Sciences at the University of Oslo, Norway, and colleagues evaluated the association of BMI with cancer mortality (overall and for 20 cancer sites) in diverse populations from Asia and from Australia and New Zealand, within the Asia-Pacific Cohort Studies Collaboration (APCSC). The APCSC is a large, collaborative data-pooling project that involves data from more than 600,000 participants in the Asia-Pacific region.

The pooled data came from 39 cohorts, with a total of 424,519 people. Of this group, 326,387 (77%) were from Asian cohorts and 175,364 (41%) were women. The mean age was 48 years, and median follow-up was 4 years.

During the follow-up period, there were 7211 cancer-related deaths, of which 4130 (57%) occurred in the Asian cohorts. The authors noted that overall, the most common cancer site was lung (20%, n = 1478), followed by stomach (12%, n = 855), liver (11%, n = 774), and large intestine (9%, n = 668).

Participants with less than 3 years of follow-up were excluded, leaving a total of 4872 cancer deaths in 401,215 individuals. After adjustment for age and smoking status, the researchers noted an increased risk for mortality in both the underweight (BMI, <18.5 kg/m²; hazard ratio, 1.13; 95% CI, 1.00 – 1.28) and obese (BMI, ?30 kg/m²; hazard ratio, 1.11; 95% CI, 1.00 – 1.23) categories compared with the normal-weight control participants (BMI, 18.5 – 24.9 kg/m²).

When looking at all cancer sites, the increased risk for death in mortality risk in obese (BMI, ?30 kg/m²) persons compared with those of normal weight (BMI, 18.5 – 24.9 kg/m²) was 1.21 (95% CI, 1.09 – 1.36), excluding lung and upper aerodigestive tract cancers. For specific cancer sites, it was:

• 1.50 (95% CI, 1.13 – 1.99) for colon,
• 1.68 (95% CI, 1.06 – 2.67) for rectum,
• 1.63 (95% CI, 1.13 – 2.35) for breast in women 60 years or older,
• 2.62 (95% CI, 1.57 – 4.37) for ovary,
• 4.21 (95% CI, 1.89 – 9.39) for cervix,
• 1.45 (95% CI, 0.97 – 2.19) for prostate, and
• 1.66 (95% CI, 1.03 – 2.68) for leukemia at 3 years after left censoring (exclusion of study participants with follow-up time less than a certain duration).

The authors did not observe any clear associations between BMI and other types of cancer, including that of the esophagus, stomach, liver, pancreas, melanoma (skin), bladder, kidney, uterus, brain and nervous system, lymphoma, myeloma, or all hematological cancers combined.

Preventive Strategies Needed

The authors note that many countries of the Asia-Pacific region are showing a sharp rise in the numbers of overweight and obese individuals, primarily as a result of a shift from traditional to more Western lifestyles. “Effective strategies to prevent the increasing proportions of overweight and obese people in Asian populations need to be developed and assessed to reduce the burden of cancer that can be expected if the obesity epidemic continues,” they write.

“However, this study does not show a higher relative risk for cancer mortality in Asian populations compared with Western populations for the same level of BMI, as has been suggested for diabetes and cardiovascular disease,” they conclude.

This treatment may be used to kill any cancer cells that remain in the chest wall, breast, or underarm area after breast cancer surgery. The treatment may also be needed after mastectomy in patients with either a cancer larger than 5 cm in size, or when cancer is found in the lymph nodes.

There are two types of breast cancer radiation therapy:

Accelerated breast irradiation

Newer approaches now being studied give radiation over an even shorter period of time. In one approach, larger doses of radiation are given each day, but the course of radiation is shortened to only 5 days. In another approach, known as intraoperative radiation therapy (IORT), a single large dose of radiation is given in the operating room right after lumpectomy.

Other forms of accelerated radiation are described below in the section on brachytherapy. It is hoped that these newer approaches may prove to be at least equal to the current, standard breast irradiation, but few studies have been done comparing these new methods directly to standard radiation therapy.

It is not known if the newer methods will still be as good as standard radiation after many years. For this reason, many doctors still consider them to be experimental at this time. Women who are interested in these approaches may want to ask their doctor about taking part in clinical trials of accelerated breast irradiation now going on.

External beam radiation

This is the most common type of radiation therapy for women with breast cancer. The radiation is focused from a machine outside the body on the area affected by the cancer. The extent of radiation depends on whether a lumpectomy or mastectomy was done and whether or not lymph nodes are involved. If a lumpectomy was done, the entire breast gets radiation, and an extra boost of radiation is given to the area in the breast where the cancer was removed to prevent it from coming back in that area.

Depending on the size and extent of the cancer, radiation may include the chest wall and underarm area as well. In some cases, the area treated may also include supraclavicular lymph nodes (nodes above the collarbone) and internal mammary lymph nodes (nodes beneath the breast bone in the center of the chest).

When given after surgery, external radiation therapy is usually not started until the tissues have been able to heal, often a month or longer. If chemotherapy is to be given as well, radiation therapy is usually delayed until chemotherapy is complete.

Before your treatments start, the radiation team will take careful measurements to determine the correct angles for aiming the radiation beams and the proper dose of radiation. They will make some ink marks or small tattoos on your skin that they will use later as a guide to focus the radiation on the right area. You may want to talk to your health care team to find out if these marks will be permanent.

Lotions, powders, deodorants, and antiperspirants can interfere with external beam radiation therapy, so your health care team may tell you not to use them until treatments are complete. External radiation therapy is much like getting an x-ray, but the radiation is more intense. The procedure itself is painless. Each treatment lasts only a few minutes, although the setup time usually takes longer.

If your breast cancer recurrence is found only in the area of the breast where your original cancer was removed and/or it’s been a long time since you were first treated, then it can often be successfully treated.

There is some uncertainty about whether having a local recurrence affects your overall prognosis. The doctor thinks that local recurrence does increase the risk of the cancer spreading elsewhere. Some others believe that a local recurrence does not in itself mean that that the cancer is more likely to spread in the future. Research is ongoing to try to answers this question and to pinpoint who may be at most risk.

People who have a regional recurrence are thought to have an increased risk of cancer cells spreading to other areas of the body. Treatments such as chemotherapy and hormone therapy are given because they work throughout the whole body.

Breast cancer can recur in the following ways

• Regional recurrence occurs in the lymph nodes near the affected breast. These “regional” lymph nodes include nodes found under the arm and in the chest wall, such as those under the breastbone or under the pectoral muscle at the front of the chest. With regional recurrence, the cancer grows from cells that were present but undetectable at the time of the original surgery
• Local recurrence occurs in the breast where the cancer first started, or in the skin and nearby tissues where the tumor used to be. This type of recurrence can happen even if you’ve had a mastectomy. In the soft tissues of the chest, cancer can grow from breast cancer cells close to the skin or behind the breast area, against the muscle of the chest wall. This type of local recurrence is called a chest wall recurrence
• Metastatic breast cancer recurrence occurs in other parts of the body, such as in the lungs, liver, bone, or brain

Treatment of breast cancer recurrence

The type of treatment for local breast cancer recurrences depends on the woman’s initial treatment. Since radiation therapy cannot be delivered twice to the same area. If she had a lumpectomy, local recurrence is usually treated with mastectomy. If the initial treatment was mastectomy, recurrence near the mastectomy site is treated by removing the tumor whenever possible, usually followed by radiation therapy.

In either case, hormone therapy and/or chemotherapy may be used after surgery and/or radiation therapy. If breast cancer is found in the other breast, it may be a new tumor unrelated to the first breast cancer. Treatment would include a lumpectomy or mastectomy and, sometimes, systemic therapy.

Women with distant recurrence involving organs such as the lungs, brain, bones, or other organs, are treated with systemic therapy using chemotherapy, hormonal therapy, or both. Radiation therapy or surgery also may be recommended to relieve certain symptoms.
