Oncotype DX® Colon Cancer Assay
Article source: Oncotypedx
Test available from: Oncotypedx

The Oncotype DX® Colon Cancer Assay quantifies recurrence risk in stage II and stage III colon cancer, beyond traditional qualitative measures. This enables an individualized approach to treatment planning. The Oncotype DX test measures a group of cancer genes in the tumor, providing a quantitative Recurrence Score® result beyond traditional measures so physicians and patients can have a more complete discussion of recurrence risk.

The Oncotype DX® Recurrence Score® result, when combined with mismatch repair status and T-stage, provides an individualized, quantitative and reproducible assessment of recurrence risk to help guide treatment decision-making for patients with stage II and stage III colon cancer.

Chemotherapy worsens outcomes in Stage II colon cancer patients.

This study followed 453 stage II colon cancer patients over a two year period following diagnosis. The study authors concluded:

In this study, stage II colon cancer patients who received chemotherapy treatment were more likely to have poor quality of life, recurrence, and all-cause mortality after 24 months compared to those who did not receive chemotherapy.

Watch-and-Wait Appears Safe and Feasible for Some Patients with Rectal Cancer

This 2020 study followed 95 rectal cancer patients who had a complete response to standard treatment – neoadjuvant chemoradiation, surgery, and adjuvant chemotherapy (nCRT ). It says there is evidence that surgery can be deferred in patients with complete response to nCRT, a strategy termed “watch-and-wait”.

Of the 95 patients, 53 patients underwent “watch-and-wait” and 42 patients had surgery. Median follow-up was 35 months.

The 3-year overall survival in the surgery group was 100% vs 88% in the “watch-and-wait” group,
rectal cancer-specific survival was 100% in the surgery group vs 95% in the “watch-and-wait” group,
and freedom from non-regrowth recurrence was 92% in the surgery group vs 85% in the “watch-and-wait” group.

The study concluded: “watch-and-wait” in lieu of surgery appears to be a safe and feasible treatment approach for patients achieving complete response to standard treatment.

Radically change your diet
This American Cancer Society study found that Colorectal cancer patients who improve their diet and lifestyle survive longer with a 42% reduced risk of death than those who do not make the changes.

Hyperthermia
This Study says: Significant improvement in clinical outcome has been demonstrated for tumours of the head and neck, breast, brain, bladder, cervix, rectum, lung, oesophagus, vulva and vagina, and also for melanoma. Additional hyperthermia resulted in remarkably higher (complete) response rates, accompanied by improved local tumour control rates, better palliative effects and/or better overall survival rates.

Avemar
This study reporting on 170 patients with colorectal cancer says the results showed significantly enhanced survival and reduced metastases formation in the Avemar treated group even though the prognostic factors of the patients were worse in this arm.

Anvirzel (Oleander extract)
This 2014 study presented case reports of 9 metastatic cancer patients who received the extract Nerium oleander. Cases included 4 colon cancer patients, 3 pancreatic cancer patients (1 neuroendocrine and 2 adenocarcinoma), 1 renal cell carcinoma and 1 lung cancer patient…The renal cell patient experienced tumor regression for 12 months with the extract alone; the 3 pancreatic cancer patients and a colon cancer patient experienced disease stabilization. Survival times were extended for all patients with survival times ranging from 32 months to 11 years for these patients with metastatic disease.

Artemesinin
This study involving 23 patients tested the anti-Colorectal Cancer properties of oral artesunate (a derivative of Artemisinin). Patients planned for curative surgery were randomised to receive either 14 daily doses of oral artesunate or placebo. During a median follow up of 42 months, there were 6 recurrences in the placebo group and 1 recurrence in an artesunate recipient. The survival beyond 2 years in the artesunate group is estimated at 91% whilst surviving the first recurrence in the placebo group is only 57%. Laboratory studies show that Artemisinin can target cancer stem cells.

Tree nuts (almonds, walnuts, pistachios, cashews etc)
This prospective, observational study of 826 eligible patients with stage III colon cancer concluded:

Diets with a higher consumption of nuts may be associated with a significantly reduced incidence of cancer recurrence and death in patients with stage III colon cancer.

Anti-parasite drug, nitazoxanide (NTZ)
Source: Labiotech.eu

A group from the University of Bergen have been testing hundreds of drugs to see how they affect cancer cells. They have now found a drug taken to treat intestinal parasites, Giardia and tapeworms, which acts as a tailored medicine against prostate and colon cancer. A widely used anti-parasite drug, nitazoxanide (NTZ), is able to break down a protein called beta-catenin, which is found at high levels in prostate and colon cancer cells and supports their growth and survival. This opens up the possibility of repurposing the drug for the treatment of these cancers.

Vitamins C and K3
This study
concluded Vitamins C and K3 have significant antiproliferative and apoptotic (cell death) effects when used in combination. This combination enhances the efficacy of gemcitabine against bladder cancer in humans.

Probiotics (Bifidobacteria)
This study concluded: Overall, considering the effects on both the cancer and normal cell lines, Bifidobacteria cocktail is the most efficient treatment, compared to other bacterial combinations used in this study. This potential probiotic has considerable “protective” anti-cancer properties comparable to the already in use drugs cetuximab and trastuzumab and is able to concomitantly down regulate EGFRHER-2 and PTGS-2 (COX-2) onco-markers and significantly ameliorate disease activity index, restore colon length, inhibit the increase in tumor incidence and prevent the progress of tumors to higher stages and grades.

In general, this potential probiotic could be considered as a suitable nutritional supplement to be used along with the drugs cetuximab and trastuzumab to treat and prevent CRC [colorectal cancer].

Chaga Mushrooms
In some studies, Chaga demonstrates selective apoptosis in tumor cells with no effects on healthy cells. Chaga extract has inhibitory and proapoptotic effects against colon cancer.

Mistletoe (Iscador)
Many studies involve using Mistletoe as adjuvant therapy in patients with cancer. One retrospective cohort study done in Europe between 1993 and 2000 looked at the use of a mistletoe extract (Iscador) as long-term adjuvant therapy in 800 patients treated with chemotherapy and/or radiation therapy for colorectal cancer that had not spread. The study found that patients treated with Iscador had fewer adverse events, better symptom relief, and improved disease-free survival compared to patients who did not receive Iscador as adjuvant therapy.

Ipilimumab
According to the National Cancer Institute, Ipilimumab is approved to treat:

Colorectal cancer in adults and children 12 years and older.
It works by helping the body to slow or stop the growth of cancer cells.

Ipilimumab

Taurolidine
An anti-biotic that is being studied in the treatment of cancer. It promotes apoptosis by inducing various apoptotic factors and suppresses the production of vascular endothelial growth factor (VEGF), a protein that plays an important role in angiogenesis.

Furthermore, taurolidine seems to reduce established lung metastases in in vivo model. Taurolidine may offer additional therapeutic options in patients with colon adenocarcinoma.
See Taurolidine

Ukrain
This study, published in the European journal of Cancer states:
In a randomised study 108 patients with advanced colorectal cancer, average 61.2 years, were included. 54 patients were treated with Ukrain as monotherapy and 54 with 5-fluororacil. The therapy results (clinical, haematological, immunological, biochemical) show that Ukrain has favourable properties in the treatment of colorectal cancer and clearly show advantages in contrary to 5-fluorouracil. Stability of the disease was reached in 88.8% and only 27.7% in the control group. The pretreatment with Ukrain facilitated the operability of the patients. The malignotoxic action of Ukrain in the clinic is confirmed by the results of pathomorphosis that gives more possibilities in operative treatment and increases the survival rate. Ukrain is a new effective drug in the therapy of colorectal cancer.

Paw Paw  Cell-Reg (PawPaw extract)
This study of 94 patients says: James Forsythe, M.D., Director of the Cancer Screening and Treatment Center of Nevada, in Reno, agreed to recruit test subjects for us among his stage 4 cancer patients. Dr. Forsythe found that the paw paw capsules, named Paw Paw Cell-Reg, when given one capsule qid, stabilized a number of patients with advanced breast, lung, prostate, lymphatic, and colorectal cancers…The product was effective whether used alone or as an adjuvant with other treatments including IGF-I and insulin-potentiation. Evidence of effectiveness included reductions in the blood levels of tumor antigens, measurable decreases in tumor sizesinhibition of further metastases, weight gain, increased mobility, enhanced energy, and increased duration of survival.

Lactoferrin
This study says:
A double-blinded parallel randomized controlled clinical trial was conducted on two groups of colorectal cancer patients to study the therapeutic benefit of orally administered bovine lactoferrin (bLF)…Test group (15 patients) received oral bLF 250 mg/day beside chemotherapy for three months. Control group (15 patients) received chemotherapy only… Although, there was a significant effect of oral bLF (250 mg/day) that indicated a significant improvement in mean percent of change of all parameters 3 months after treatment, there was no significant difference between results of patients in the test group and patients in the control group after treatment. This result suggests that oral bLF has significant therapeutic effect on colorectal cancer patients.


Bergamot juice extract

This study says: In this study we demonstrate that Citrus bergamia juice extracts (BJe) reduces CRC [colorectal cancer] cell growth by multiple mechanisms…high concentrations of BJe induce oxidative stress causing DNA damage. Our study highlights the role of BJe as modulator of cell apoptosis in CRC cells and strengthens our previous hypothesis that the flavonoid fraction of bergamot juice may play a role as anti-cancer drug.
